using the tool you see in the pic below,
to get there:
photoshop
Rectangular Marquee Tool (M)
up the top, pull down the "Style" drop-down menu (should be on "Normal" as default)
put it on "Fixed Aspect Ratio"
and punch in "1.25" and "2" for portrait - or "2" and "1.25" for landscape layout.
then as you select, it'll hold it in 8x10 ratio. perfect!
i skim read the other suggestions - and doing those is a pain in the arse.. you'd haveto guess what size to resize to, and it complicates things alot
also, let the photo place resize them, they might have a better process to stop the image becoming jaggered and stuff..
aslong as it is in the 8x10 ratio (which you just did) it doesn't matter if it's 10,000 resolution, just tell them or write on the form that only resizing is needed - although thery should understand as they open it.
good luck - did i help?
Just curious, how is the marquee tool easier for cropping than just using the crop tool? To make an 8x10 using the crop tool, you just type 8 and 10 for the width and height, mark the crop area and then double click it. It doesn't get any easier than that.
It's also easier to resize your selected area with the crop tool, rather than re-selecting over and over with the marquee tool until you get the starting point and size correct.
I tend to leave the resolution alone, and just make sure I send the lab the correct aspect ratio to match the print. I've done up to 12x18 this way with good results.
