I have a work-related problem in Photoshop that I -really- need some help on!

I have been tasked with a great number of files of photos that need to be converted through Photoshop. The photos (and there are several thousand of them) all have a common problem, that being that they are in a vertical format which needs to be converted to a horizontal one, and they are all substantially underexposed.

Here’s what I have been doing to rectify this problem.

I load the files into Photoshop. I then open 20 or so photos at a time. As each photo appears, I click on Images, Rotate 90 degrees CCW. After this is done, I go back to Images, Brighten/Contrast, and then adjust the photo accordingly. As each photo has been underexposed by the same amount, I usually go to the limit on both the brightness and the contrast.

Needless to say, this is a tedious procedure, and each 150 or so photos takes me three hours or so.

Here’s my question…..

Is there any way to convert the files I have uploaded in batches? In other words, for each group I choose, I would like to rotate all of them 90 degrees counterclockwise, and, of course, I’d also like to do the same for the brightness/contrast part as well.

Is this possible? Any help on this would be much appreciated.

Tx….Dan

Absolutely. Create an action that does what you want, then run it in batch mode. Batch mode can be cranky, so you may want to split your images into folders of 100 or so images each, and do each folder separately. Or let it grind away on them all, and see what happens.

Be sure to keep a copy of your originals (!).

If you have to do the same thing to all of them, do it once, record it as an action, make a droplet and then drop the files onto the droplet on your desktop.

After this is done, I go back to Images, Brighten/Contrast, and then adjust the photo accordingly.

Others have already explained how to create an action that does what you need.

However, I strongly urge you, if you care about the photos, to stop using Brightness/Contrast and learn to use Levels or Curves instead.

The Brightness/Contrast command is only intended ofr novices, and it degrades the quality of your pictures. It is a "linear" command, which means that it reduces image quality by clipping detail from the hilights and/or shadow of the image.

Levels and Curves are both "nonlinear" commands; they can do the same thing as Brightness/Contrast, but without degrading the quality of the image by clipping detail.

If the image is simply underexposed, Levels may be all you need to fix it, and learning to use the Levels command is not as difficult as learning to use the Curves command. In fact, Auto Levels may fix the images better and faster than Brightness/Contrast, and you need not learn the intricities of Levels at all!

Look, a little Tough Love here. When you pay a fortune for the state-of-the-art photo-imaging program, would you not think that it can automate such a simple, ordinary friggin task as that? Others will answer, but the word here PRESS HELP AUTOMATE. Intuitive enough, moneybags?

That’s a great site for non-artistic folks to master bevel and emboss. Too bad that all you can do, Mike.

If you decide you want to tweak the brightness or levels for each pic while batching the rest, you can put in a pause, with a preset adjustment, then as you OK it, the batch will continue…
