I have an image(raw file) of my son I want to crop and then print off at a larger size 20x30 inches or thereabouts.

Using the crop tool in CS4 I select the dimensions and crop the size I want. I've entered the dimensions in tool bar. For some reason when I bring the ruler up using 'R' the ruler is showing in cm's when I have selected a crop size in inches. How do I change this?

Also I want to see how my image will look at roughly that dimension. How do I zoom in and know what it will look like a 30x20?

I do the 30x20 crop and I have no idea if the quality will be acceptable?

Any tips gratefully recieved :)

Also when you guys do a crop and blow up do you usually get a cheap smaller print as a test first to check the exposure/brightness looks fine before spalshing on a larger image?
 
Thanks Paul :)

Any ideas on how you then know if the crop and expand to 30x20 will look acceptable. Anyway to preview this on screen before you buy?
 
Hi. If you don't have sufficient pixels to print at 20 x 30 inches at, say, 200 ppi (i.e. 4000 x 6000 pixels) there are only 2 options: upsize using the resample in the image>image size dialog or some other software specific to resampling. The more you have to upsample, the riskier the quality will be. Adding pixels that weren't there to start with means Photoshop makes a 'best guess'. Your best bet is to check the 100% view to see if there are any problems. If it looks OK then its probably going to be fine printed. The thing with a 20x30 in is that you don't tend to look at it as closely as a, say, 7x5 in, so a drop in quality may be acceptable.

Click to expand...

You could crop a 10x8 portion of the image out and print it on your photo printer if you have one to see how it will stand up to large printing.

Now this is not scientific but as a general rule that works for ME (notice the disclaimer) if a image looks good noise and sharpness wise at 50% veiwing on screen then it will generaly make a decent print.
 
Just press ctrl+r to get the rulers up then right click on the ruler to set cm, mm, inches etc.
When the image is open, to view print size after you have cropped to the size you want, press Z and at the top on the tool bar click on 'print size' this will zoom in or out to the actual size that the image will print at.
 
What size is the file? Example 3000 x 2000? If we know the size we would have an idea if it will look good at 20x30...
