Please provide information about the Action performed in the batch.

In addition to Sharon's question, can you also (briefly) tell us what kind of retouching or effects you are having the Action/Batch perform? It's possible you're running into tool or effect changes between the 2 versions.

When you upgraded to CS6, did you rebuild the action? Or did you just load your CS5 action into the new program? What you may have to do is rewrite your action in CS6.

Although the changes are minor, there are usually programming refinements and performance updates for adjustments (and similar effects) between versions of the programs. From what I have seen, the Levels adjustments have had slight changes and seem to be more sensitive than the CS5 version.

Are you using the same source image file that has not been adjusted? On the same Machine and environment. Perhaps you can post your results of CS5 and CS6.  Make two copies of the source image file and post these three files source image file results of cs5 on copy 1 and the results if CS6 on copy 2. If posible post a link to the action set and name the action in the set.

yes, I did rebuild the action. The action is changed according to the needs of the image.  But, it happens every time (the over lightening or darkening)

You need to use the exact same action on both versions of Photoshop and also make sure the default settings for Auto Levels are set the same for these are changeable and  Auto Level was enhances in CS6 and there is a new Adobe Photoshop default

Using Ps CS6 (13.0) on OS X 10.6.8

OK, I recorded Image>Adjustments>Levels... Auto followed by changing high input to 155.

I didn't go as far as doing a batch because I can confirm that replaying the Action gave a different result than the manual operation which was recorded by the Action.

I repeated the test by recording the Action again with another image. Again, the result was a difference between manual operation and Action playback.

See screenshot of the Action and the difference between the result of manual operation and Action playback, amplified for clarity by an exposure of +10. Other images and adjustments may give a far greater difference, of course.

Adobe added a new Algorithm to Auto Levels in CS6 and made it the default for Autolevels. "Enhance Brightness and Contrast" is the new algorithm and default each image will be processed differently then the older  algorithms options which are still available and can be set as the default. "Enhanced Monochromatic Contrast", "Enhance Per Channel Contrast" and "Find Dark and Light Colors"

Did you try setting CS6 Autolevels default to auto options to the CS5 default setings not use the CS6 default Here is what I see in CS5

JJ, I used CS6 entirely to compare manual operation versus Action playback. I recorded the Action in CS6 and played it in CS6, so the result should have been exactly the same as doing the adjustment manually. However, there was a repeatable difference with both of the two test runs involving different images.

After having made the default change JJ suggested above, I could not get a difference between manual and automatic operation in Photoshop CS6, nor between Photoshop CS5 and CS6, with the test images I tried.

Would you be willing to post a small version of (or part of) one of your images, Dan?

Thanks, at least I'm not totally crazy, just a little.

I bet you were totally sane until using CS6

We have a problem.

This post concerns Ps CS6 (13.0) on OS X 10.6.8 only. It has nothing to do with CS5.1 or any other version of Ps except CS6.

CS6 Action playback with Levels does not reliably produce the same result as the manual operation that was recorded.

The original image "Original_IMG_0737.jpg" has no embedded profile, so I set Working Space to sRGB then opened the image and assigned sRGB to it.

I set the default for Levels Auto to the same as that which Noel used - "Enhance Per Channel Contrast" - then confirmed that the default was maintained.

Test 1: Levels Auto and no further adjustment of controls. Manual op and Action playback produced identical result. A repeat of the test gave the same match of manual and playback.

Test 2: Levels Auto and input high control changed to 210. Manual op and Action playback were different. A repeat of the test gave the same mismatch of manual and playback.

I set the default for Levels Auto to "Enhance Brightness and Contrast" then confirmed that the default was maintained.

Test 3: Levels Auto and no further adjustment of controls. Manual op and Action playback produced identical result. A repeat of the test gave the same match of manual and playback.

Test 4: Levels Auto and input high control changed to 145. Manual op and Action playback were different. A repeat of the test gave the same mismatch of manual and playback.

-------

Action playback in tests 2 and 4, where Auto was followed by a change to the input high control, was identical in test 2 and almost identical in test 4 to the manual result which is obtained when Auto mode is "Enhance Monochromatic Contrast" and input high control is changed.

For some reason, an Action containing a Levels Auto and change of input high control produces a result that's either identical to, or very close to, Levels Auto mode "Enhance Monochromatic Contrast" and the changed control, regardless of the actual Levels default Auto mode.

Three images follow.

1. Manually operated Levels Auto "Enhance Brightness and Contrast" and input high 145

2. Playback of Action containing Levels Auto "Enhance Brightness and Contrast" and input high 145

3. Manually operated Levels Auto "Enhance Monochromatic Contrast" and input high 145

The second image should have matched the first, but it is far closer to the third.
