Why do my photos look good in PS, but look oversharpened on DPC? I'm going to e-mail my Macro IV entry to work and try submitting from there, and see if it makes a difference. The same thing happened to my Hummingbird entry in the Balance challenge.

Are you viewing at 100% zoom in Photoshop?

It will not make a diffrance!

How are you saveing the file - as close to 150kb?

Are you working in sRGB in PS?

Not sure that's his problem. From the looks of his hummingbird photo, it appears he's got the radius of the Unsharp Mask filter far too high given the size of his image.

It would certainly help to know what settings are typically used when this problem shows up.

I usually just crop and then reduce the size to 640X480 and then do Auto Level, Auto Contrast, and Curves. I generally don't play with the other options. Yes, I always check the photo at full size to see how it will look. Thanks.

It's better to work on the full-size. Only after you finished you resample to 640 and as the last step you sharpen. 0.3 radius @100-150% with 0 to 2 treshold does the trick most of the times.

IMHO auto-anything is autocrap.

Do you apply sharpening to the final 640x480 image, and if so, with what settings?

I always reccommend viewing your finalized entry file with Internet Explorer, or other web browser, before you upload it to dpc. That way you get a chance to see it as the voters will (most of whom will be using IE) but still can go back into your editing program if you see something you don't like, such as apparent oversharpening.

Do you always sharpen your images - I just posted my entry to everyday objects with out sharpening it. I thought it look good as it was.

Excellent discussion. This information should help me - I couldn't figure out why my pic looks so different when I view it at home vs. on DPC. Also, needed the technical help (i.e. auto-anything is auto-crap and when and to what level a pic should be sharpened, etc.

Thanks

Don't forget the tutorial on sharpening right here on dpchallenge.

The type of display you're using to view may also make a difference. Everything tends to look extra crisp and sharp on an LCD monitor as opposed to a CRT (tube-type monitor) -- especially if that CRT is aging, out of alignment, convergence is off, etc.

I noticed that with one of my photos... Looked fine on my main computer (older CRT), but at work (LCD) WOW were those some sharp lines.

It looks better on my work PC. I also edited the original here at work and resubmitted. My home PC might just be getting worn out. Hell, I'm still on dial-up. Thanks.

I´ve had pretty good results latly bye sharpening full size images (~3000x2000 pix) 100-250%, rad. ~2 and threshold ~1. Small images (~640x480) 50-100%, rad. ~1 and thershold 0-1.

It wouldn't be AOL would it? AOL, and some other providers, do image compression to deliver faster content to browsers, especially over dialup. This can seriously impact how a photo looks. That could be the difference between home and work as well.

There was a forum the other day on this - I don't know how to make a direct link, but it's titled "Web browser and photo results!" and under "Photography Discussion". One of the posts had instructions for how you can turn the "feature" off.

Yep. I have AOL. I'll look up that thread up. Thank-you.
