Let's start with an image. This one is, as you can see, 2882x1921 pixels. [Editor's Note: Click images to see larger versions.] It happens to be set at 240 dpi, but that is irrelevant.


Click for full size



Now select the marquee tool. In the tool options choose "Fixed Aspect Ratio." Say we want to target an 8x10 print; we then choose an aspect ratio of 5 wide by 4 tall (could just as well be 10 x 8, 20 x 16, or whatever multiple you like best).


Click for full size



Now select the crop you want. The marquee will constrain you to choose something that will fit in the 8x10 print.


Click for full size



Once you are satisfied with your selection, go to the Image menu and choose "Crop."


Click for full size



This is your cropped image, and this is how your 8x10 print will look like.


Click for full size



Lastly, you need to resize it for printing. Go to the image menu and choose image size. Uncheck the "Resample image box." Then, in the document size portion of the dialog, choose inches as your unit of measurement. Set the width to 10 inches; the height will automatically change to 8. The dpi will also change to reflect the pixel density. In this case, the resolution ended up being nearly 230 dpi, which is plenty good for printing.


Click for full size



Say you had attempted to print your image as a humongous 40x32 poster. In that case, the resolution would have dropped to 55 dpi, which would have looked pretty awful when observed at close distance.


Click for full size



If you use 120 dpi as a safe boundary, you can print your 6 megapixel images up to 20x30, provided they are in focus and properly sharpened.

This new FAQ question will encompass the DIY camera fixes that are available to end users.

Beware, not all of these things are condoned by camera manufacturers, and some may actually void your warranty.

That said, there are many things that you can fix/do yourself that might save a trip to the service center. There are also some things that may enhance your equipment's current abilities.

How to fix a loose hotshoe on Canon dSLR's.
•Firmware/software support:
Canon
Canon 300D firmware hack (enables more features)
Nikon
Konica-Minolta

•Dirty sensor on your dSLR? Use the Copperhill sensor cleaning method.

Winter-proof your camera.

•Homemade shutter release cables:
Canon 300D
Another for the 300D and Pentax *ist-D/DS/DL
Extension for 20D cable release
•Make your very own macro ring light!

Fix back/front focus issues with your 300D/350/20D. Not for the faint of heart.

I am sure that there are many, many things that I haven't thought to put here. If you have any corrections, or would like to add something, post it in the thread or just send me a PM!
