hello

can you tell me please how to perfom a task in batch in many image files, without having to open each in photoshop?

I want to 'auto-contrast' the images

2. how does this function performs? I mean what does photoshop do in the image? also, can I set parameters for this function? and adjust it to my needs?

3. if I do this functions many times to a file, it will change it every time?

thanks
