Printing

[Fast Glass]

So does that mean a 350 dpi image of 3,500x3,500 pixels would print 35"x35".

3500 pixels / 35" = 100 dpi. Sooo, I guess you can't print at 35" and 350 dpi.[]


Resolution divided by print size equalls dots per inch.

Are pixels and dots the same thing?

Yes. One pixel equals one dot, but your printer will print at whatever print resolution you set. Lets say 1400 dpi like on my R1900, the print may only be 100 dpi but the printer will interpolate it to 1400 dpi. There is only 100 dpi of dietail, but it will be much smoother and wont be asjaggedand pixelated.

On my monitor many of my images still look good at full size (1:1, or Ctrl Alt 0 in PS). What would full size be in printing terms?

You just do the math in reverse, most moniters are between 80 to 100 dpi. Lets say 100 dpi. Take 3500 pixels and divide by 100 dpi, thatequalls 35".


If you ask Daniel Browning what's the ideal resolution he'll tell you 1200 MP or so![:O]


BTW, 3500 pixels at 2 to 3 aspect ratio is about 8 MP, using a rebel XT,30D or the like?[8-|]


Hope this helps,
