dpi

Prenderb

I'm a bit thick. I've been this way for a while now. Sometimes it results in me doing something then being sure I've done it wrong. Like uploading photos in jpg format off the camera at an image size of about 4-5mb - then noticing that they should be in 300dpi size.

If I've uploaded a file that big, is it big enough? Or is there a bit of post-camera processing I should do? I'm not doing it tonight for 'tis bedtime, but could do something tomorrow - I have the GIMP.

Thanks for your help -

a bit of a noob when it comes to this.

for computer screen viewing 72 dpi is grand, for print, high as possible, 300 is perfect

Thanks,, I meant to ask is an image 300dpi because it's 4mb or do I have to make it that way?

Open to correction, but dpi is the print resolution - so if you want to print a 6x4" image it must be at least (6*300)x(4*300) pixels.

i.e. 1800x1200 pixels.

Setting the dpi adjusts the on screen rulers, and print previews and stuff, to translate pixels to inches.

Resizing your picture, and colour depth and image complexity affect image size (in bytes), 'dpi' doesn't.

I suppose the question is - big enough for what?
