When do you decide on a print size? For example, I have a shot that needs 8x10 to get the best "look" and crop. However, we all know that 8x10 does not reduce correctly to 4x6. I like to print on 4x6 for proofs.

Can anyone give me some advice or your production..printing workflow?

Thanks,

Most basic image editting programs will have a cropping tool.
When you crop a 4x6 to an 8x10, you will just chop off part of the longer edge of the 4x6.

Hmmm yes I've seen this delema (sp?). So If my original is an 8x10, then I will never get a "perfect" copy on a 4x6? So what is the most popular "size" to start off with when beginning your editing?

Thanks,

What does your camera produce? My Rebel does 4x6 ration (8x12 if you prefer).

For a wedding I shot I did all 4x6 proofs. The 8x10s i printed I simply cropped myself, carefully,so that i could choose what got cut off. Fortunately i left enough room for that when I took them. (portrait orientation - leave more headroom, landscape leave more side room - gotta plan ahead).

I know one photog that simple crops everything to 4x5, and has a pro lab that prints her proofs in that size. 8x10s are then easy.

Should we talk 5x7? No, I think not.

Becareful in PS - the crop tool will resample if you let it. You may not want this. What i have done is to make up 4x6, 6x4, 5x7, 7x5, 8x10, and 10x8 as well as 'free crop' with NO DPI settings as my crop tool defaults/presets. You can then resize quickly without resampling.

I have had no problems printing 8x10 at 200DPI, even resampling up from a crop. (via walmart and winkflash.com, they both use fujifilm printing).

Well most cameras' sensors are designed for a 2:3 aspect ratio (4x6). If you know that you want to make an 8x10, 5x7, or different aspect ratio, you should shoot "loose" on the subject so that you can crop it later.

I think that medium format cameras, have aspect ratios of 4:5, which is an 8x10.

When I open an unedited image from my D70 in PS it sizes the image to
10.027 x 6.667. What can I do with such a size? Since it is not a "common" paper size, will I always have to "crop off" something in order to get to 4x6 or 8x10?

Please excuse the Newbe...

Mine does that too. The size of the picture is 2000x3008 px. The extra 8 pixels throws off the 4x6 ratio. Usually I crop all my pictures at 300 ppi for printing. I've heard that all the extra pixels aren't used by the printer.

Does anyone else know why the sensor captures pictures 8 px longer?
