I am entering my oil on canvas painting into a competition. A friend photographed it for me but has cropped too much from the bottom. It needs to be 800 DPI at least and very clear and a good colour match to the original. Entries close at 5pm on Sunday 27th August. So this is urgent.

No offers were made on this task.

Cheryl, is the art to be judged only on screen, or will the judges (or you) be printing it for judging?
Which camera is going to shoot 800dpi lol. DSLR are 300dpi
Vincent, you don't know what you're talking about. You need to do more study on DPI.
No correct Vincent, the dpi depends on the size of the camera sensor and the size of the canvas. A 24 Megapixel camera can shoot a 19 x 12.5 cm canvas in 800 dpi.
That's right Peter. For some reason, even seasoned photographers seem to think that DPI is fixed, yet it is a totally arbitrary measure based on resolution and size of print.

If this artwork is to be judged on screen only, DPI is completely and utterly irrelevant.
Hi Cheryl, what are the dimensions of you painting?
For argument sake, if it would be A4 format which is 20 x 30 cm = 8 x 12 inch you would expect a 61 Megapixel camera, correct.
Cheryl, what is the size of the canvas?

Apart from the bottom cropping, was your friend's result satisfactory? Can your friend not try to photograph it again?
