dissenting.
I must respectfully dissent because of my belief that: (1) by its opinion in this case the majority has seriously undermined the long-established rule that the opinion of an expert witness must be based upon facts in evidence; (2) the majority has also approved a practice which will make it much more difficult for juries to properly evaluate opinions expressed by partisan expert witnesses; and (3) references by the majority to Rules 56 (2) and 56 (3) of the proposed Uniform Rules of Evidence are not only unnecessary, but may further confuse the law on this subject, in the absence of some explanation.
The majority, recognizes that “[T]he rule is ordinarily stated that an expert witness’s opinion must be based upon facts in evidence.”① According to the majority, “[T]his statement of the rule is too broad, *600as is demonstrated by State Highway Comm. v. Arnold, 218 Or 43, 341 P2d 1089, 343 P2d 1113 (1959),” but “it is not necessary for-us to explore tbe boundaries of the rnle because all of the material facts relied upon by defendant’s witness were in evidence in this case, * *
In State Highway Com. v. Arnold et al, 218 Or 43, 66-69, 341 P2d 1089, 343 P2d 1113 (1959), this court recognized an exception to the general rnle in eases involving expert opinions relating to the .value, of land to the extent that the foundation for the opinion of an expert witness on land value may be based in part upon hearsay relating to comparable sales, when such hearsay evidence is of a type customarily and reasonably relied-upon by such expert witnesses in such eases. In that case, however, the hearsay statements were in the record and this court made it clear that it intended to retain the rule that expert opinions must be based on facts in evidence.②
*601In James v. Falk, 226 Or 535, 541, 360 P2d 546 (1961), this court recognized a further exception for the “omission of immaterial facts.” With those two exceptions, however, this eonrt has continued to recognize the rule that the opinion of an expert witness must be based upon facts in evidence.③
This case does, not fall within either of those exceptions or qualifications. Neither does the majority urge any further exception to that rule. Instead, 'the majority questions the validity of the rule itself.
In this ease, the opinion of defendant’s' expert witness -was admitted by bim to be based upon those “key” items; (1) a written' report by plaintiffs’ expert *602witness; (2) a “brochure” describing- the chemical formula of the spray; and (3) photographs of bean plants. Those three items were included in a file delivered to defendant’s expert by defendant’s attorney. Defendant’s expert had that file, including these items, before him at the time of his testimony. Thus, all three of these “key” items could easily have been offered in evidence by defendant’s counsel, assuming that they were what they purported to be and could be identified as such.
Plaintiffs’ attorney made timely and proper objections to the opinion of defendant’s expert on the ground that it was based upon facts not in evidence. Despite those objections, defendant’s counsel never offered the written report in evidence. Through another witness he offered in evidence a “sample label,” which was never shown to be the “brochure” in the file used by defendant’s expert witness. The photographs of bean plants, although obviously relied upon by defendant’s witness on the assumption that they were photographs of the allegedly damaged bean plants in plaintiffs’ field, were never shown to be photographs of those bean plants, but were only identified by one of the Paeschke brothers, not an expert, as photographs of bean plants which “looked like” the bean plants which he saw in plaintiffs’ field.
1. The failure to offer in evidence the written report relied upon by defendant’s expert witness.
The majority would excuse defendant’s failure to offer in evidence the written report by Mr. Harrison, plaintiffs’ expert, as relied upon by defendant’s expert witness, Dr. Freed, upon the ground that “Mr. Harrison testified to the same facts and explanation that was contained in his report” as shown by a comparison of *603the written report (which was never introduced in evidence), with “excerpts from Mr. Harrison’s testimony.”
In my view, this not only misconceives, hut would largely defeat, the fundamental purpose of the rule that the opinion of an expert witness must ordinarily be based on facts in evidence. The reason for that rule is that in the absence of the facts on which the expert has based his opinion there is no way by which the validity of the opinion can be determined by the jury.
Thus, as stated in Devine v. Southern Pacific Co., 207 Or 261, 273, 295 P2d 201 (1956):
“An expert must state his opinion upon facts presented in the record, for the reason that a jury must determine the weight to be given the opinion, and, without knowledge of what facts the expert accepts as true, an evaluation of his opinion is impossible. Henderson v. U.P.R.R. Co., supra; Lippold v. Kidd, 126 Or 160, 269 P 210, 59 ALR 875.”
See also 2 Wipmore on Evidence (3d ed 1940) 792-793, § 672.
In my view, we should not approve a practice under which an attorney can (1) offer the testimony of an expert witness who has examined a report prepared by the expert witness for the opposing party and provided to him by the attorney; (2) ask his expert witness to express an opinion based upon his examination of that report; and then, (3) despite objection for lack of a proper foundation for that opinion, fail to offer in evidence the written report on which his expert witness relied. The fact that the expert witness for the opposing party has given testimony which may include, among other things, the same material as set forth in his report does not, in my opinion, provide a good or sufficient excuse for fading to offer the written report *604in evidence, at least if it was available for that purpose, as in this case.
The reason is that the jury, in undertaking to determine the validity of the opinion of defendant’s expert witness is entitled to have before it the document on which he relied as the basis for that opinion, at least if it is available for that purpose. In this day of increasing reliance upon the use of expert witnesses, some of whom are partisan advocates, it becomes in.creasingly important that juries be given better, not poorer, means by which to determine the credibility of expert witnesses.
For these reasons the jury should not be required to remember (if it can) and to then winnow through the voluminous testimony by persons who prepared such documents. To impose such a burden upon the jury in a case such as this, in which that testimony was lengthy and the credibility of the expert witness is crucial to the outcome of the case, is not realistic and would hinder, rather than help, the jury in the discharge of this most important function. For a recent discussion of. this problem, see Comment: Opinion Testimony of Expert Witnesses: Oregon’s New Rule, 52 Or L Rev 443, 453 (1973).
Neither is it realistic nor fair to require the trial court or this court to undertake the burden of examining all of the often voluminous testimony of the opposing expert witness so as to determine whether that testimony has covered all of the significant points in- his previous -written report, on v/hich defendant’s expert relied as the. basis for his- testimony.
At least this is true when, as in this ease,- these problems could have been so easily avoided simply by offering the written report- in evidence, as required *605by application of the nsnal practice to the effect that one who offers the opinion of an expert witness has the burden to see that the facts on which his witness bases his opinion are offered in evidence.④
For these reasons I would hold that the opinion testimony of defendant’s expert witness should have been excluded upon the ground that the written report of Dr. Harrison, upon which he relied as one of the three “key” items as the basis for Ms opinion, was not offered in evidence.
2. The failure to offer in evidence the “brochure” in the file used by defendant’s witness.
Dr. Freed testified that the second “key” item on which he relied as the basis for Ms opinion was a “circular or brochure” which was also included in a file supplied to him for examination by defendant’s attorney and which he had before him at the time of Ms testimony.
When Dr. Freed then undertook to state Ms opinion plaintiff objected upon the ground, among others, that this “brochure” was not in evidence. Dr. Freed was on the witness stand at that time, with the file in his possession, and it would have been a simple matter for defendant to then offer the “circular or brochure” in that file used by Dr. Freed and have Dr. Freed identify it as the “circular or brochure” on which he relied. Defendant did nót do so.
Subsequently, during the testimony of another witness, Ottó Paeschke, who was apparently one of the owners of defendant Paescb_ke Farms, was asked to *606identify what he referred to as “a specimen label of a can of spray like which I used,” saying that the labels on the cans actually used “have been took to the dump.” That document was printed on both sides, but only the “specimen label” side was offered in evidence, counsel stating that the other side was “not relevant.”
There was no testimony that this document came from the file which Dr. Freed had examined or that this “specimen label” was the same as the “circular or brochure” referred to by Dr. Freed as one of the three “key” items relied upon by him as the basis for his opinion.
Defendant’s counsel says in his brief that these two are the same. Plaintiffs’ counsel, however, does not concede that they are the same and points out that there is no such testimony in the record.
I cannot understand why defendant’s counsel did not offer such testimony, when it would have been so simple for him to do so, if such were the fact. Because, however, there is nothing in the record to show that the “specimen label” subsequently identified by Mr. Paeschke was the same as the “circular or brochure” relied upon by Dr. Freed as one of the three “key” items in arriving at his opinion, it follows, in my opinion, and for this additional reason, that the opinion of Dr. Freed was improperly received because it was based in part upon facts not shown to be in evidence.
3. The photographs of bean plants, although offered in evidence, were not sufficiently identified.
Upon reading the testimony of defendant’s expert in this case it seems obvious that when he was sent the file which included these photographs, among other things, and also when he gave his testimony in this case, *607he assumed that they were photographs of the actual bean plants in plaintiffs’ field and at various locations as shown on accompanying maps, which were not received in evidence.
As previously noted, his testimony was received on the condition that defendant was subsequently able to “get the photographs in evidence.” The witness who later identified the photographs, however, could not say whether or not they were photographs of the bean plants in plaintiffs’ field, but only that “the condition in the pictures is the same condition as I saw in my examination of the field.” Accordingly, defendant’s offer of the photographs was not on the basis that they had been sufficiently identified as photographs of the bean plants in plaintiffs’ field, but that “they show damage like that observed in the field.”
The majority says, without citation of authority, that these photographs were admissible without further identification because they “constituted demonstrative evidence.”
In Parker v. Smith Lumber Co., 70 Or 41, 47, 138 P 1061 (1914), this court stated the following rule:
“* * * Photographs stand on the same footing as diagrams, maps, plans, etc., and, when relevant to describe a person, aplace, or a thing, photographs are admissible for the purpose of applying the evidence in a cause, and assisting the court or the jury to understand the facts. The photographs must be shown by extrinsic evidence to be true and faithful representations of the place or subject as it existed at the time involved in the controversy.
“The photographs, however, need not be verified by the oath of the photographer who took them. The foundation for their introduction may be laid by the evidence of anyone who can testify as to their correctness as a representation or likeness,' •
*608“Whether a photograph is sufficiently verified or not is to be determined by the trial court, in the exercise of a sound discretion: * * (Emphasis added)
To the same effect, see State v. Gibbons, 228 Or 238, 243, 364 P2d 611 (1961).
This court has not previously had occasion to consider whether the failure to identify a photograph as one taken of the identical place, thing or subject in issue in a particular ease will require exclusion of the photograph in a case such as this, or whether, in such a case, testimony that what is shown in the photograph is “like” the place, thing or subject in issue is sufficient.
The answer to this question would appear to depend upon the purpose for which a photograph is offered or received in evidence. A photograph may be offered as a photograph of a particular person, place or object involved in the particular case. In such a case, the photograph, in order to have probative value so as to be relevant, must be a photograph of the particular person, place or object involved in that case.
In order to sufficiently identify and authenticate a photograph so as to make it admissible in evidence for such a purpose it is necessary to first establish: (1) that it is a photograph of a person, place or object that is relevant to the issues of the case and (2) that it is a true representation of that person, place or object. See 2 Scott, Photographic Evidence (2d ed 1969) 314, 334, 352, §§ 1022, 1023, 1026; Jones on Evidence ,(6th ed 1972) 345, 354, $§ 17.:49, 17:51; and 3 Wharton’s Criminal Evidence (13th ed 1973) 279, 637. See also McCormick on-Evidence. (2d ed 1972) .531; § 214; 3 Wigmore on Evidence. (Chadbonrii rev 1970) 256, § 798; 7 Wigmore on Evidence. (3d. ed 1940) *609564, 569, §§ 2129, 2130; Paradis, The Celluloid Witness, 37 Colo L Rev 235, 239 (1965); Note, 1957 Wis L Rev 494, 495; and 1 Will L J 596, 601 (1961).⑤
When a photograph is offered or received for such a purpose, as held in Sisk v. State, 232 Md 155, 158, 192 A2d 108, 110 (1963):
“* * * [T]he rule that the admissibility of photographs is ordinarily left to the discretion of the trial court does not come into play until there is competent extrinsic evidence showing the photograph to be a true representation of the scene or object which it purports to represent at the time when the appearance of such scene or object is relevant to the inquiry in connection with which the photograph is offered. * *
See also 2 Scott, supra, 317, 358-359, §§ 1022,1027.⑥
On the other hand, a photograph of a person, place or object may have probative value so as to be relevant, depending upon the issues in a particular case, even though it is not a photograph of a person, *610place or object, involved in that particular case. Thus, photographs of railroad cars or machines substantially similar or identical to the ones involved in an accident and photographs of a posed or reconstructed.scene of a crime are often admissible. See cases cited in 2 Scott, supra, 623-633, § 1145 n.84. Of course, as stated in 2 Scott, supra, 314, § 1022 :
“* * * [I]f the physical objects pictured are not themselves relevant, reducing them to photographic form does not make them so.”
When, however, photographs are offered for “illustrative purposes,” as in this case, there are still requirements which must be satisfied. Thus, as stated in 2 Scott, supra, 632, § 1145:
“Sometimes it is not possible to photograph the identical object involved in a legal controversy and in such circumstances the question arises as to whether photographs of similar objects may be introduced in evidence. The inability to photograph an object may arise when it is in the possession of the other party or when it has been lost or destroyed. By the weight of authority photographs of objects similar or identical to the objects involved in a case are admissible in evidence when properly verified. Proper foundation should be laid by showing (1) that it is impossible to obtain by reasonable effort a photograph of the object involved in the case, (2) that the object represented is an exact duplicate as to dimensions, etc., (3) that no material changes have been made which may affect the value of the photograph as evidence, and (4) that the photograph otherwise represents the true situation.
"See also Wychgel v. States Steamship Go., 135 Or 475, 489-90, 296 P 863 (1931).
These requirements were'not satisfied in this.case. *611It follows, in my opinion, that these photographs were not properly received in evidence.
4. The references to Buies 56 (2) and (3) of the Uniform Buies of Evidence.
It is ohvions from the length of time that has elapsed since the hearing of arguments in this case, as well as from the fact and nature of this dissenting opinion, that this ease has been the subject of prolonged consideration by this court on the matter of expert opinion testimony.
The majority concludes its opinion by the making of reference to Rules 56 (2) and (3) of the proposed Uniform Rules of Evidence. Although these references by the majority to those rules are now set forth in a footnote, they are wholly unnecessary to the opinion and, in my view, may further confuse the law on this subject in the absence of some explanation.
Those proposed rules, and, in particular, the provisions of Rule 56 (2), are inconsistent with the previously established law of Oregon that the opinion of an expert witness must ordinarily be based on facts in evidence — a rule which is not questioned by either party to this case.⑦
The majority, however, has made it clear that it does not intend by its opinion in this case to overrule or modify that long-established rule in Oregon. Thus, the majority has not adopted Rules 56 (2) and (3). Nevertheless, I believe it to be unfortunate that the majority, while making such a statement, should nevertheless proceed to make what thus becomes a wholly unnecessary reference to those rules. But for that *612statement by the majority, the references by it.to those proposed rules might well be subject to possible misunderstanding in such a manner as to cause further confusion on this subject.⑧
For all of these reasons, I must respectfully dissent.
McAllister, J., joins in this dissent.Decisions by this court recognizing that rule include the following:

To the same effect, see: Peterson v. Schlottman, 237 Or 484, 487, 392 P2d 262 (1964); James v. Falk, 226 Or 535, 541, 360 P2d 546 (1961); Stuhr v. Barkwill, 215 Or 285, 289, 332 P2d 603 (1959); Carruthers v. Phillips, 169 Or 636, 645, 131 P2d 193 (1942); Mount v. Riechers, 140 Or 267, 274, 13 P2d 335 (1932); Lippold v. Kidd, 126 Or 160, 168, 269 P 210 (1928); Gillilan v. Portland Crematorium Assn., 120 Or 286, 296, 249. P 627 (1927); State v. Willson, 116 Or 615, 619, 241 P 843 (1926); State v. Simonis, 39 Or 111, 116-118, 65 P 595 (1901).
Thus, in State Highway Com. v. Arnold et al, 218 Or 43, 341 P2d 1089, 343 P2d 1113 (1959), we said, at 69:
“We have held that an expert cannot-give an opinion unless *601the facts upon which his opinion is based are disclosed by his or other witnesses’ testimony. Henderson v. U.P.R.R. Co., supra. We regard this as a salutary principle because it permits, the jury to judge the weakness or strength of the premises upon which the witness bases his conclusion. We regard this principle as applicable in cases in which the witness is called upon to testify as to value. We wish to make it clear that what we have stated here concerning the admissibility of testimony of expert witnesses as to value is not intended to modify in any way the rules previously announced by this court relating to the testimony of experts called to testify in other types of cases such a,s in Tuite v. Union Pacific States, et al, supra; Henderson v. U.P.R.R. Co., supra, and Lippold v. Kidd, 126 Or 160, 269 P 210, 59 ALR 875. Those cases did not involve the testimony of expert witnesses testifying as to value, and the rules stated with respect to the testimony of the type of witness involved in those cases are in no way modified by this opinion.”
Thus, in Peterson v. Schlottman, 237 Or 484, 487, 392 P2d 262 (1964), we held that “the riile is-well established, that the facts assumed in a hypothetical question must be supported by evidence in the case.”'
And in Highway Commission v. Fisch-Or, 241 Or 412, 399 P2d 1011, 406 P2d 539 (1965), we held that the hearsay evidence which may be considered by an expert witness on the value of land in a condemnation case is admissiblé only for the limited purpose of “showing' the basis of, and to explain, the expert’s opinion of the value of the property in question,” and not as substantive evidence of value. •
If portions of such a report are not inadmissible, and were not relied upon by defendant’s expert, any such portions can be deleted and the remainder of the report received in evidence.
For these same reasons courts have held that a photograph of a physical object cannot properly be received in evidence for such a purpose in the absence of preliminary proof that it is a picture of the object involved in the particular case. Hupfer v. National Distilling Co., 114 Wis 279, 90 NW 191, 193-94 (1902); Annot., 9 ALR2d 899 (1950); Hammond Packing Co. v. Dickey, 183 F 977, 978 (8th Cir 1911); Semet v. Andorra Nurseries, Inc., 421 Pa 484, 219 A2d 357, 359-60 (1966); Hadges v. New York Rapid Transit Corporation, 259 App Div 154, 18 NYS2d 304, 305 (1940); and Meadows & Walker Drilling Co. v. Phillips Petroleum Co., 417 F2d 378, 381 (5th Cir 1969). See also State v. Tatum, 58 Wash 2d 73, 360 P2d 754, 756 (1961). Cf. State v. Gibbons, 228 Or 238, 243, 364 P2d 611 (1961); Jones v. Sinsheimer, 107 Or 491, 498, 214 P 375 (1923); and Natwick v. Moyer, 177 Or 486, 493-94, 163 P2d 936 (1945).
Defendant cites Burnham v. Eshleman, 257 Or 400, 479 P2d 501 (1971), and State v. Gibbons, 228 Or 238, 364 P2d 611 (1961). We have examined those cases and find that they, do not hold to the contrary because in neither of those cases was there any question but that the photographs were pictures of the persons, objects or scenes involved in those cases.
