This is an embarrassing question but I have to ask it anyway…
How many DPI is best for image reuse?
iStock says that the optimal image is 5 x 7 x 300dpi but at the same time they say that bigger is better. When I convert my older images that were not shot in RAW to 300 DPI and look at them ‘print size’ in CS2, they are actually much smaller than they were before at 72. But is the quality better?
But if an image is originally 72 DPI or 240DPI, is it still an advantage to convert it to 300? Do we gain anything?
When I have my camera set to RAW the resolution is 240 DPI. When I set it to “large” I get 72 DPI when I open the images in photoshop.
In CS2, ‘New document preset resolutions’ is set to:
Print resolution: 300dpi
Screen resolution 72 dpi
Finally: My RAW converters let me select any DPI for processing (workflow options in CS2), but how many DPI is the image actually as recorded by the image sensor?
So what’s the proper settings? What’s best for stock photo sites?
I’m sure I’m missing the obvious…
