File format help

[webmonkeyuk]

Doing alittle project for work and ive come across 2 questions im not sure about,

Q- In what format would you save the following and why?

b) A finished photographic image intended for use on the Web.

c) A finished image for commercial printing.

I think you would use a jpeg for the web? something to do with the low file size? but im not sure what and why for C)

Any ideas chaps

By comercial printing do you mean getting a digitial photo printed by somewhere like photobox.co.uk or are you a giving the images to a client for some sort of design?
If it's the latter you should save the file in a .tiff at a minimum of 300dpi. Might also want to convert it to CMYK.
If it's for digital photo processing/printing then I'm not 100% as I've not used Photobox before but I'm sure there will be a guide on the website.

erm sorry should have said im not actually producing any images its just a writen project that im doing and those were the question im not sure about

OK, here's how I do it.

Everything is shot in RAW for maximum flexibility in post processing. Initial conversion is to TIFF as is all post processing - simply because it's an uncompressed format so no compression artifacts.

For web publishing I use JPEG, and small resolutions (600 x 400 px max). There are two reasons for this, 1) file size is low keeping download times down & 2) small image size limits potential for theft as it's too small to use for anything other than the web.

For commercial printing it depends on what the printer can cope with. Ideally TIFF if possible to keep the image uncompressed but for the likes of Photobox it needs to be JPG so I save a single copy at the maximum quality setting from the original TIFF.
