I'm having the exact same problem. I hope someone is able to help solve the issue. I was just looking at the 3 pictures I have open and the 3 you have open, and I can't but help wonder if the probem is because it appears there are 2 with the same exposure. I thought it was suppose to be +.03, 0 and -.03 but when I look at the images on the bottom, it says EV 0.00, EV 0.00 and EV - 0.03. Any ideas?
Just to verify.
You tested on CS5 32 bit and it worked OK?
I am having a similar problem with the same step in the "Adobe Photoshop CS5 Classroom in a Book" using the images provided with Lesson 05 on the CD. I am running a fully updated, CS5 Extended on a Windows 7 64 bit machine. My instructor has followed the same steps on her 64 bit without any issues but another class mate has the exact same results as I with Photoshop 5.5. In my instance, when looking at the bottom of the Merge screen the EV values are photo #1 EV 0.00, #2 EV 0.00, and #3 EV -0.03 I am a beginner to Photoshop but from the assignment instructions it appears that the values should each be different. Please see my screenshot.
Do you also have CS5 Extended 32 bit?
If so, is the merge correct with 32 bit?
As I originally posted .. I only see the problem in my CS5 64 bit.
The CS5 32 bit merges ok.
I'm having the same problem. Has anyone figured this out?
Hello, are the merge to HDR settings strictly the same between 32 and 64 bits?
How are images opened, from Bridge, or Photoshop? Maybe the default settings of Camera Raw are not the same in their 32 Bits (Bridge) and 64 Bits (ACR hosted in Photoshop) versions?
The thing that i notice is the images are virtually the same. Meaning all three look like virtually the same exposure.
To get an idea of how hdr works, you need images with more deviation in the exposures.
Try the images in your cs5 sample>merge to hdr folder and see how they work and if you see any differences between doing them in the cs5 32 bit version versus the 64 bit version.
"To get an idea of how hdr works, you need images with more deviation in the exposures."
Where did you find this information?
How much deviation is not enough?
With the deviations in the files supplied with the Classroom in a Book lessons all worked OK with CS5 32 bit. But failed with CS5 64 bit.
The Adobe sample files you mentioned do work using CS5 32 and 64 bit.
However, that does not answer my original question.
Well there could be something wrong with the sample files included in the Clasroom in a Book for photoshop cs5 and maybe the reason nobody has verified your results and offered a solution, is that we don't have those particular files.
If we could get hold of the three .dng files from the book, maybe someone could see how they work on their end.
These three files / sizes .. is it possible to zip them up and send them?
You can use something like YouSendit or Acrobat.com and then post a link to the zipped folder here on the forum.
Never done it prior but will give it a try.
With Acrobat dot com I could send a (free trial) 33MB zip file but it has to go to an e-mail address ...
Send it to yourself and post the URL here.
"Send it to yourself and post the URL here." ...
I could send it to myself but I do not know where the URL is that needs copying ...
I got the zip file on YouSendIt ( free lite 14 day trial version).
Now I have to figure out how you can retrieve it!
They must have sent you an eMail with the link in it, no?
YouSendIt may have changed; in the past they were free indefinitely for files up to 100MB.
I signed up for the "lite" version and I think the max upload file size is 50MB for each upload for 14 days.
I sent the invitation to share the folder I have to my own 2nd e-mail account.
I will try to find the URL you mentioned.
The way it is designed .. I should be inviting peole to share the folder .. not like a link that anyone can use .. but I have not gotten into this real deep yet.
I will see what I can do here.
I got the link you asked for:
** Note: I used 7ZIP to zip the 3 files. Let me know if you guys got the download ok?
Note: The link you sent will expire : February 23, 2012. Some spam filters may block the email you just sent. If your recipient has trouble viewing your file(s), try sending with your own email client instead.
Thanks for the examples.
So far i don't see the same thing in the 64 bit version of cs5 on vista, but to me it just looks like all the files are the same and someone just set the exposure in camera raw and then saved three separate dng files.
If you open all three files into camera raw, select the Select all button and then choose camera raw defaults from the side menu in the basic tab, all three look like exactly the same exposure.
If you open all three files from camera raw into photoshop and look at the file info>camera data, the data looks exactly the same.
Though that really doesn't explain what your seeing though.
"info>camera data, the data looks exactly the same."
Would that be the same as the three data (screenshot) text files I posted above (Jan 24th) ... those show 3 different exposures.?
No that data shows the camera raw settings used in the file.
The camera data tab in file info shows the settings used on the camera.
If they are indeed three separate photos, i would think the info under the camera data tab would show some difference in the exposure, f stop or something.
(i'm still looking for issue you showed in the hdr dialog of cs5 64 bit)
What happens in the 64 bit version if you uncheck the auto align box?
If that makes a difference, then it's probably because the images are cropped in acr.
(the dng file settings) (open one of the images and under the crop tool select Clear Crop)
Anyway, unless i'm missing something, it seems those images serve no purpose in learning hdr.
I was able to complete the assignment properly ONLY after opening in 32 bit. Even with my instructors assistance, there was no way to Merge to HDR Pro following the instructions while in 64 bit version of Adobe CS5.
I have had the same problem under CS5, so I bought the new CS6-version of Photoshop. ==> no difference! I get the same x64 results as in the very first posts. I do not have a 32-bit version installed, so I cannot verify the 32-bit results. The exposure values given under "Camera RAW" in Bridge of the three sample pictures are -0.75 - 0 - +0.75, so a merging should be possible. My system: Win 7 x64 Ultimate. Could it be a problem of the video card or video card manufacturer? Mine is a Nvidia Quadro FX5800 with two 30" monitors.
... 1 hour later: I have tried the HDR merging with a photo-sequence I took myself. The 3 pichtures had an aperture spread of ±2. Here the merging succeded. From this behaviour I conclude, that, since the 32-Bit sw-version seems to work without problems, that the x64 algorithm has a bug and does not compensate possible saturation effect in the resulting image correctly.
For me the problem seems solved, we just have to wait for a corrected x64 HDR-math in one of the next updates.
Thanks for feedback.
I have CS6 for 1 week now (64/32 bit) and really like it.
I have only admired the new interface and tested "text" modes/features and verified no errors loading CS6/working with images/various file types.
In next days I will do some HDR testing with the sample files from Classroom in a Book using CS6 and also test using my own images from my new Canon G12.
Has anyone tried this on an installation of Adobe Photoshop CS5 or CS5.1, with an older version of Adobe Camera RAW installed?
I had this issue reported to me by a faculty member who is attempting to teach this lesson in one of our Mac Labs. She has taught this lesson in the past without issue, but, recently reported this issue. We recently upgraded our photography lab's equipment, which included new iMacs, and updates to software installed in the lab, including the CS5.5 Design Premium suite. I'm able to replicate the issue on all the computers in the photo lab, with the same issue as others described above. I then went to try to replicate the issue on my personal computer with CS5.5 installed, and, surprisingly, the HDR merge worked successfully. The only signifigant difference on that computer was that it was running Adobe Camera RAW 6.6, rather than the current 6.7. I then went ahead and updated the Camera RAW on that computer up to version on 6.7, and the problem doing the merge with these specific files returned as it had in the photo lab.
So perhaps this is a combination of 64bit and Camera RAW 6.7? I can't get the 32bit workaround to work on the Mac's I'm testing. Any suggestions would be appreciated.
I got my 64 bit to finally work by going to EDIT_PREFERENCES_PERFORMANCE then the AVANCED SETTNGS button and de-selecting "UseOpenCL". I noticed this was greyed out in the 32 bit so de-selected itin 64bit and it works fine. I have an ATI AMD 5700 series card. I do not know if this will work for anyone else.
"I got my 64 bit to finally work" .....
Which 64 bit product?
I tried "EDIT_PREFERENCES_PERFORMANCE then the AVANCED SETTNGS button and de-selecting "UseOpenCL"." in my CS6 64bit.
I rebooted the PC to ensure a clean test.
But this did not work for me. Same problem with CS6-64 and the HDR files.
Are you sure you last tested in CS6 64 bit? Check about Photoshop (Help menu) and verify 64 bit.
My 32 bit CS6 is the only one doing it corectly.
33 posts in this thread over a period of 9 months and two major versions, describing a reproducible bug using widely available data...
How is it no Adobe staff has seen fit to respond?
I tested it several times now, in fact prior to posting htis reply I will try again. Also, just in case, I first installed the latest drivers for my card, they came out 8.15.2012. Again, beng somewhat less than a novice, I have no idea what I am doing, this just happened to work for me.
OK, PS 64 bit is doing its thing with the three files....oh no....I did this about 7 or eight times last night (my wife was ticked tht I was still on here) and it worked. Now it is not. I am back at a complete loss. 32 bit is still fine. I tried openeing 32 bit and 64 bit, it only lets you have one open. I went back to 64, no success. Sorry for the premature happiness/hopefullness.
This sucks. I will try and speak with someone at ATI/AMD on Monday. Adobe tech has now twice responded htat it is a Card and/or driver issue. I am ALMOST tempted to purchase a brand new card to try that, but the one I have is approved.
WIN7 64 bit
PS CS6 extended 64bit
ATI RADEON HD 5700 sries
AMD Radeon Graphics processor (0x6888)
Approx total memory 745 MB
It is so easy to start CS6-32 bit by accident for the test.
So, next time you start CS6, go first to Help / About Photoshop ... and verify it is 64 bit.
Then proceed doing the HDR test.
Yes, I made sure each time, plus the segregated start menu differentiates the two quite a bit. However, so pointless now. Did you post what your graphics card is? I have to go back through, I remeber someone saying NVIDIA.
Nvidia, GTX 550Ti 1GB
Have you talked to them at all? I have to leave to help a friend move. Bye
10:58 AM - just got back, PS is absolutely in 64 bit mode, it worked again. I will not post anymore about it not working, working, not working, etc. I will post once I can communicate with ATI.
It just seems if it is a card or driver I should have the problem every time?
