I just don't understand that my digital camera that I set high which that is 5.0 and the result is 144dpi. I need to made 300 dpi, what is the suggust or is that way of digital camera like that? I am processing to learn and complete the project I am working on. I just have to accept that low dpi but want to know for the next time .

You usually can't change the dpi in your camera settings, but you can change in with your image editing software. Do you use photoshop? If so, just open your image, go to Image > Image Size. Uncheck Resample Image (so that it retains the same number of pixels). Enter 300 for the resolution value. Click ok.

Thanks that what I think the same but wasn't sure about this.

Thank for many!

I just join this and forum looks exciting and hope I can learn something to share and even I learn something to share with you guy!
