Re: [Help] Increase DPI ? I hope my reply isn't too far off the mark

you'll notice on the 14th line UP from the bottom
Quality Levels ....... Normal, Fine, Superfine
I do believe that THIS is the setting you are looking for .. you just need to find it in your menus ....
but that's not to imply that what everybody has to say about RAW and PRINTING isn't accurate  .. but if you shoot JPEG you may want to look for this menu item .. it will probably be with your image size (2048x1536, for example)
I have a Canon A75 (3.2 MP) .. and "Superfine" seems to be 180 dpi .. not terribly happy about that .. but it IS just a point and shoot camera |

Vallejo, CA | DPI doesn't matter at capture, it's the number of pixels that matters.
Take my camera, the Minolta Maxxum 7D. It is a 6 megapixel camera (3008x2000).
When I shoot JPEG the image size is the following:
3008x2000 at 72 DPI with a print size of 41.8 x 27.8
When I shoot RAW the image size is:
3008x2000 at 240 DPI with a print size of 12.5 x 8.3
All that matters is how many pixels you have, that's your "bucket" of data. So, let's make the bucket of data a bucket of paint. You can either paint a very large wall with very little paint coverage (less DPI) or a smaller wall with very dense paint coverage (more DPI).
On digital cameras (even DSLRs), the superfine/fine/standard modes set the level of compression (and in some models the image size, in others image size may be separate as on mine I can choose size and quality), and some cameras may increase the DPI, but that does not matter, again, all that matters is the number of pixels you capture.
Now,there is of course a caveat to this. A lot of printers won't print over the DPI that they are rated at and just discard the extra data. So if you're going to print something at 4 inches by 6 inches at 300 DPI that is when you either want to crop it to that size by using the crop tool set to proper values or then you do a resample/resizing of the image to bring it to what you need.
For example, going back to my camera at 3008 x 2000 pixels to print a 4x6@300 DPI I need a 1200x1800 image so what I do is use the crop tool set to 4 inches by 6 inches (or 6 inches by 4 inches if it's a landscape oriented photo) and 300 DPI. Then I crop the image and when I'm done it's perfectly sized at 4" x 6" @ 300 DPI.
To reiterate, DPI does not matter until you are printing all that matters is the number of pixels you have and from there you can calculate your print sizes at various DPI settings.

Some assembly required, your mileage may vary, no pixels were harmed in the writing of this post. Brain cells, though, are a different matter. You want fries with that? |
