I have a set of photos on my PC, around 100, and I am going to go through them and crop them to fit onto 6x4 prints which I'll order online. The pictures are for the most part different resolutions. My question is, how can I figure out how to crop it down to the perfect size? If I use the crop tool in photoshop and set the width to 6inches and the height to 4inches, is that enough? This was my original plan. Then, I saw that 1600x1200 photos would need to be cropped too. One of my digital camera's takes pictures at 1600x1200, so I thought this would be the standard size of 6x4 prints - but it looks like even those should be cropped according to the crop tool on photoshop, which when set to 6x4 takes a 1600x1200 photo down to 1600x1067. Is this correct? This may sound kind of confusing, but I hope someone can help me. I just want to know how to crop my photos properly in order to get good looking prints - is the photoshop crop tool okay? I don't want to spend time cropping them, have them printed and end up with crappy stretched photos.
