first select the photos you want to adjust and save them to a new folder. Then open PhotoShop. JUST DO IT!

Then open one of those images, and create a new action set, and start recording.

Go to Image>Adjust>Auto Levels. Then turn off the recording, and undo the effect you just did on the photo. Now turn the recording back on, and close the image when it asks to save hit yes.

Now then go to File>Automate>Batch> and select your source and destination foleders (which is the one you just made) then select the new action you just created, and run it.

Seriously the whole process should take less than a minute to set up.

Or hit me up, and I'll do it for you at cost.
