Crop fixed size in pixels not possible in PS?
I am having a hard time finding out if this is possible. I have always cropped in photoshop freely but now I need that all the images have the same crop 1500x1500 pixels a fixed crop window where I can move this crop around the image (the images are 7500 x 6000 or bigger) . Whatever I do if I enter does dimensions it does not matter if in ratio or WxHxResolution I always get an aspect ratio size. That means those 1500x1500px are not locked. If I type it on ratio it fills the canvas to crop a 1x1 aspect ratio (the whole canvas that is much larger than those 1500 x1500 px I want. I don't want to drag it smaller or bigger I just want a fixed crop of 1500x1500px inside the image.
If I do WxHxResolution I also don't get what I want. I get a final image of 1500x1500 image of whatever crop I do. Much worse as it does interpolation.
So does this simple option is not available in photoshop ?
