Got a quick Photoshop question to do with cropping photos.
I've searched and searched for this but can't find any info: is there a
way to make Photoshop maintain a fixed aspect ratio with the crop tool,
but keep the original PPI? Basically I want to crop 6x4 images (and
other sizes) out of larger photos, but I don't want Photoshop
upsampling/downsampling them - I just want it to crop out the pixels I
Failing that, how do you do your cropping? Allow Photoshop to
upsample/downsample to 300 PPI?
