i want to post a picture on the internet, what should the Pixel resolution be.?

Question

I looking to buy a digital camera

Answer 1

Depends. If you want the size to be exactly the same and with the best resolution ..save the picture as a .tiff with a 600 DPI resolution. Generally such a high resolution is not required unless you are publishing your work. For the Internet a resolution as low as 150 DPI will serve most purpose. Check out the resolution on the computer at 100% magnification before you submit. Hope this helps. If you are looking to buy a digital camera, and use it for day to day snapshots. 3.3 MP is enough. Anything greater than that will be excellent, but will take more storage space.

These maths games are fun, but Deb's numbers are way off.
For a computer monitor, you only need 72 dpi. For making prints, you'd want 300 dpi. That's a fantastic difference in resolution.
And for the internet, smaller is better. A 600x800 pixel image is all you need to fill the better part of the screen. That works out to just half a megapixel.
I normally shoot pictures at best image quality for making great quality prints. Then, for my web gallery, I resize these shots to 600x800 pixels AND reduce the image quality. The end result is that an original 5MB jpg file (from a 10 megapixel camera) shrinks to just 200kb or so.
Any camera you buy - even an ancient model with just 3 megapixels - has more than enough power for internet pictures. You have nothing to worry about.

if you have photoshop go to image size and go to the pixels and make it 800 on the long side and then go to resolution and set it to 72, that is what i have always been told to use for web images
