Since I got the D300, I have not been posting as much on here....and the simple reason is that I am having a very hard time getting a 65mb file down to under 200kb and still look good.....

so I am looking for any help or ways to save the file so that it will come in at under 200....

Right now I do all my processing work and then click save as, jpg, and then it brings up a slider......and on most of my images I am having to go all the way down to 4 or 5 and at that it looks like crap.......

thanks

Re-Sizing & Sharpening for Web

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.
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.

Danny, my brain hurts just reading what you wrote....but thanks for your efforts....

My PS skills are very limited.....and I do understand about the resize, sharpen, and resize again for the web presentation......and even at 60% the images look like crap and too compressed.....

at least for me they do.....

That's weird, Darren, I've worked one gig files that had a quality of 85 to get them under 200kb in Save for Web.
I size mine first so the longest size is 720.
My recent post started out at 485 megs, was 1.57 meg when shrunk to web size and the to get it under 200Kb I had to move the slider to only 87%.

Darren, Open in 16-bit PhotoPro RGB colorspace. Resize by 50%. Apply Sharpen 2 times. Convert to sRGB at this time. Resize to 720 on largest end. Use "Save for Web" to get under the total BS 200Kb web size limitation (this is 2008, not 2001 isn't it?). Aren't 1TB HD's now under 200.00 ?

Anyway, this works for me - even on multiple images stitched to make 1gig files, the end results are not too compressed looking generally.
