Hi, Im new to NPN and tried to post my first pictures. I did have a hard time with resizing my pictures. How do I resize a 3888x2592, 17.3 MB picture to the size to be posted in the galleries.I also use the Marc Adamus Sharpening technique sometimes. Do I use this technique before before I resize or after? The way I resize for flickr is that I resize first to a 7.5X5 but my file is still fairly big, then I use the Marc Adamus Technique, where I double the size from what its going to be. ( usually I resize it to 700 pixels length wise, so I double it to 1400, sharpen it and bring it back to 700. This works fine for flickr but not for PNP, if I do it that way my files are still to big to upload to PNP.I finally ended up resizing in photoshop's "Save for Web". I'm I making any sense? .Thank you for your time.

And right at the top is an interesting thread on this.
All the best Danny.

I wrote an article on this but I don't know if Jim E. is going to publish it. Here's DeWitt's Quick & Dirty Guide to Marc's technique in cookbook form. Your mileage may vary. All commands are from Photoshop CS3
1. Convert to sRGB (Edit > Convert Profile)
2. Crop appropriately
3. Set white point and black point (Image > Adjustments > Levels)
4. Optionally, use Curves to fine tune the blacks, whites and greys (Image > Adjustments > Curves)
5. If necessary, delicate changes with Brightness and Contrast (Image > Adjustments > Brightness)
6. Bump the Saturation a bit to compensate for sRGB's palette by +5 - +10 (Image > Adjustments > Saturation)
7. Adjust image size to 1.333 times the final posting size (1200 pixels for NPN) (Image > Image Size)
8. If there are sharpness issues, optionally apply Sharpen (Filter > Sharpen)
9. Adjust image size to the target 720 pixels (Image > Image Size)
10. Apply Smart Sharpen (Filter > Smart Sharpen)
11. Fade the luminosity (Edit > Fade Smart Sharpen > Luminosity)
12. If there are serious noise issues, apply your noise filter (i.e., Noise Ninja)
For bonus points, you apply these adjustments in Layers, giving you greater flexibility. But it's not mandatory. This is admittedly simplistic, and derivative to several folks' published work here, but it's what I use.
Thank you so much for that step by step, Jim. I've taken it and printed it to keep for the next image I post. I'm not a Photoshop newbie but it's a faster way than I've been using and gives great results.

Hey Jim, resend that article! Somewhere along transitioning between PCs I seem to have lost it (your article, that is...).

Thanks everyone for the quick response, Jim I tried your way but my files are still over 200kb
I think I'm still doing something wrong.
Ah. The 13th step. Steps 1-12 get you to the right physical dimensions and a [possibly] nicer looking shot. If you want to post the photo at NPN, as opposed to linking the photo to a site you host, then
13. Save for the Web, using the slider to get the shot under 200 KB (File > Save for Web > JPEG). If the level of detail in your shot is high, you may have to go into the 60% range to meet the 200 KB limit.
