One more thing, please (and you all are being of great help over the last weeks; so thank you):
I work for offset printing (quality magazines, record sleeves, etc), so my images must be 300 dpi as some of you must well know.
Starting with a DP1M or DP2M file, exporting with SPP with the highest (16?) bits as a TIFF.
The result I think is a TIFF/180dpi image with 26x17 inches (66x44cm). 180dpi aren´t enough for me.
With Photoshop open there and resize WITHOUT interpolation for 300 dpi what are the final dimensions? Inches and centimeters.
I only have one Sigma RAW file to make this test. So to confirm my results...
Digital files don't have a dpi. They may have an ASSIGNED dpi, and that is arbitrary and can be whatever you set it to. If you want one million dpi - no problem. but the resulting size will be very small.
Digital files are unitless pixel-size - what you need is dimensions in pixels x pixels. Then divide by dpi, and you get size in inch.
If the DP1M, you have 4704x3136 normally active pixels. Divide by your wanted dpi, get size in inch.
4704/300 = 17.7inches
3136/300 = 10.4inches
Thank you for the clarification.
I knew this but could not dress it in words as good as you did.
When I meant that I would get back to Luis with the output size I meant the nominal output size at 300 dpi, given the pixel dimensions. Roughly A3 in print.
