 Post subject: DPI
PostPosted: Mon Aug 20, 2007 12:50 am 
I was wondering how to lower my DPI on my computer because some of my pictures, although they are perfectly clear, have become somewhat grainy. I have Windows XP.

Are you talking about your screen resolution?

I really am not all that sure but when I had posted a picture on my flickr account and it was a little bit grainy my friend said to lower my DPI.

I'm still not sure what you mean, sorry. Could you post a link to the picture that looks "grainy"?

Hi Nathan,

Since you mentioned somewhere in your Flickr profile your're anti-photoshop, well there's only one way that I know of since I'm do a lot of Graphic Desgin and Digtal Darkroom work.

1. Open the image in Photoshop
2. Go to the top toolbar and hit: Image
3. Go to resize and select Image Size (NOT CANVAS SIZE)
4. Type 72 under the Document Size divider

P.S. Check to see if the side drop-down box say pixels/inch not pixels/cm

Really Nathan: You should put the pic (plus a crop of that grainy part) up on flickr and give us a chance to see what we're talking about here.
Hopefully the pic has all EXIF-data intact, then we have all we need to know.
Plroblem is (or may be): if you have manipulated the original with software, that might be the reason for the degradation (perhaps you did it inadvertently) and it might be that the EXIF-data are corrupted. Th major question then is: Do you have the unmanipulated original file as it came directly out of your cam? Then place that too on flickr...
-----------
B.t.w.: interesting thread! It's more "on-topic" than others in this section :wink:
