Digital camera dpi

Hello all,

I have a question regarding the quality of a digital picture. If I take a picture in 2048 x 1536, when I open in Photoshop it says 72 dpi. This is my question:

I want to take this picture and use it in a graphic ad that is going to be printed in a final output of 300 dpi. Do I need to change the resolution to 300 dpi? Will this be a true 300dpi image?

Thanks in advance.

Yes, I do this all the time in my business. All you need to do is change the resolution under image-->image size. Your image size now is about 28" x 21" at 72dpi. When you change the resolution to 300dpi your image will be a standard 5" x 7" photo. Now the image will print out great assuming you don't want to make it bigger then a 5" x 7".

If you want it bigger your quality of the final product will degrade rapidly and not print well. The best thing to do is to take another picture, of whatever it is, at a higher camera image quality setting (more pixels) or get a print made of the picture then scan it at a high resolution (i.e. 1200dpi but this all depends on how big you want it).

Hope that helps,
Cuda
