I got a comment on my "Something New" photo mentioning the "Jaggies" on the scissors.
I didnt notice these before but now I do.
I was just wondering how to get rid of these without spot editing, and why they are on this photo, but none others I have taken. |

| It's usually an unfortunate consequence of re-sampling the image to DPC specs, and loss of data due to JPEG compression. Sharp lines, especially on the diagonal, are usually the most affected elments. |

Thanks.
Is there any way you know of to avoid this? |

I think that depends greatly on your software. I use Photoshop 6, and RATHER than "Save As" and let Photoshop do its normal JPG compression, I do "Save for Web". This lets you see the original and the compressed JPG at the same time with the ability to adjust compression rate, and other things. I have has pretty good luck in that I can maintain close to 100% accuracy (to the eye) at between 100 and 200K, which is perfect for DPC.
Hey konador, Are you familiar with the director Jean-Pierre Jeunet? Your haircut photo reminds me of a freeze frame for almost any of his films. I got a kick out of it for this reason. If you don't know him already, you should check him out on imdb.

I did some research because I'd forgotten the program name, but I found it. If you're not using photoshop, or if you have a version that doesn't include the "Save for Web" option, SmartSaver Pro does the same thing.

| Thanks alot dawn! I'll download the programme now. Also, I have'nt heard of Jeunet, (only film of his I've seen is Alien Resurrection, and didn't really take note of his name) but I'll take a look now. |

Hey, you're right! I've seen all Jeunet's films. I was wondering why I liked that photo so much :).
It was a good shot konador. |

PS6 "Save As" DOES allow you to change the compression rate, showing you the final file size as you make the adjustment - so you can choose the best compression to make the 150k cut-off
