| Ok guys..this is the process I go through. I take the original shot at at a vga size. that means 640 x 460. I crop, edit, to my usual gimp editing and after I am done, I convert to jpeg if I have to, and then I save it to my harddrive. Usually my photos are anywhere from 30kb to 80kb. Now after I upload to DPC...I get some fuzz, only in certain photos, like 2 out of every 10 uploaded. Are my photos too compressed? |

Why on earth are you taking your photos a vgs size? You really should be taking them full sized and then resizing as needed.

Yes, by taking photos with a 640x460 size you are making your 5mp camera into a 0.3mp one.
Start large 5mp, crop then re size down to 640x460.
If you tried printing a 640x460 vga size pic it would be very small.

I would suggest taking the original shot as large as you can. Do all of your color adjustments, and what not first. Only when it looks the way you want it to, should you crop/minimize the size of the shot. Save the original in a 16-bit tif file for printing later on, before you crop/minimize.
AFTER THAT, use the USM (unsharp mask) to sharpen the image.
Convert to 8-bit jpg for upload to DPC.
Hope that helps.

VGA is 640 x 480, right?
If your images are from 30 - 80k, depending on the colour and detail, that could be 'way too compressed'. When I get a 30k image (not often), it's usually something without much detail against a plain background. |

Yes they are. What's happening is that you are shooting the original image with a 640 x 480 size limit. After you crop, you are losing however many pixels you have cut out.
As a general practice, you should make the originals in the largest format your camera will allow, in your case, a 5mp TIFF. Once you have processed the shot, then you can save for the web, at 640 x 480, and 150kb. I'm not familiar with the Gimp, so maybe someone else can help you with the resizing steps.
Good luck, and keep up the good work.

Another suggestion, zigzag: click on LEARN at the top right of this page, then select TUTORIALS from the drop-down menu and take a look the tutorial, "Using Photoshop to Prepare Photos for DPC Challenges" by EddyG. I found it very helpful.
(Edit to add): Sorry, I see that Scott beat me to the punch.

If you're producing the sometimes funny and always original photographs under the conditions you subscribe, well, all I can say, is once you get the digital technical stuff out of the way, uh, folks, stand back!
(That "Kill Bill" scene made me LOL, er,how you say? ROFLM*O) |

| the only reason why I take my photos in vga size is so I can cram up as many of them in my camera as possible. I can always resize them to 5.0 later on. But from now on, I will resize them first before processing them for dpc...thanks to you all..I learned so much in 2 months from everyone's helpful comments. |

Resizing or resampling after you take the photo isn't the same as taking the photo at full resolution in the first place. That just doesn't work. To get fine detail in your images you need to take the photo at a large resolution and then make it smaller afterwards, not the other way around.

You beat me to it Jimmy ;-)
If you take an image at 640x480 then no amount of upsizing will recapture the detail you have lost. You are doing yourself no favours by killing the detail. Buy a bigger mem stick or have some spare ones in your bag.
But shoot at full resolution.

Yes, take your original shot in the largest (best) mode. That probably means upgrading to more memory for the camera, but if you're truly wanting the best image when re-sized, don't throw away pixels before you start.

| I did not know that. I thought resizing is the same regardless of the mode its shot originally. I do have a 256mb memory stick, so I might as well make use of the space. I just guess Im gonnoa go back and retake some of my favorite photos |
