photography question

it s not the filesize you should look at but the DPI = dots per inch. this is the resolution of the image. for high quality printing 300 or more DPI is usual (that's for books, magazines, etc.). on home printers 150 or 200 DPI will do.

btw, for printing use TIFF or high quality JPG files

yeah .. first off the size of the file is not relevant :)

jpeg is dynamic compression ^^

TIFF is the standard as it's non destructive. (even if using zip or tgz internal compression)

like dtr says, check the dpi ..

with the dpi, the size of the destination format you can calculate the needed pixel resolution :)

That really depends on how 'pro' your printer is. I'd use 300 as a minimum standard on any printer, even for cd booklets.

yes, you should allways use 300 dpi...

and indeed save the final version as tiff

But tiff can be really prohibitive in size for one image. Really depends what the main usage is.

Yah. I got a 200MB per page press folder for JMF, a PDF one, and a jpeg. When I print the jpeg or the tifff, difference is minimal. It really depends on the printer, the file, etc.; But in most cases high qsuality jpeg will do the trick. There's a reason why it's the standard format...

Now, if you go to a real printer and need A2 or A1, ok...but he's talking about an A4 print...

ok guys, if you want to continue the discussion without me, go ahead... I kinda heard what I neede to hear...

and found some sort of graphic about it: see the bottom of this page
