Hi everyone,
I have now made 1000's of images and I am really looking forward to printing. I am one of those people who want to understand things technically before I jump in and I am afraid I am stuck on a number of technical issues as far as printing is concerned. This will be very dry so fair warning!
I want to print at 300dpi. I have scanned 35mm film at the highest resolution for my scanner before its optics cannot give better results. This is 3600dpi for the 35mm, giving an image that is 300dpi at slightly smaller than a3 size. I would like to print my best images at a3.
This is my question;
If I upsize my images to a3 without upsampling, the DPI will drop below 300, probably to around 270 or 280. Can a printer actually physically print in a sliding scale of DPI and just print at 270 DPI giving a print of good quality that does not require upsampling (and the subsequent loss of quality that interpolation will cause?)
Or
(as I suspect) will the printer/printing software resample image to 300 dpi (and probably to a worse job of it than I would do myself in photoshop?)
I will happilly accept slightly below 300dpi if it means not having to upsample my images. However, if upsampling is going to happen in the background, I would rather do it myself and prepare images specially for printing.
I have been trying to find the answer to this question online and among my technically adept photography colleagues and I haven't been able to get to the bottom of it. I hope there are some techy printer folks out there who know the amswer to this!
