Nice shot but something is missing and I can't exactly put my finger on it. Maybe there is a loss of sharpness because of the small size on the blog. Those branches should be really sharp but I can't tell from a small print size. Colors look a bit muted but can be adjusted. Did the scene look like the photo?

Martin, did you click on the thumbnail to see the larger sized picture? Yes, the colors were muted that day, so I chose not to further enhance. In fact, I was considering converting this shot to black & white.

Interesting. I think something is missing too! Perhaps the lack of a strong center of interest?? WT

Thinking back to the moment, I think I was going for the look of the layers between the bare tree branches, the green trees, then the peak in the background. --WT

Did you sharpen the photo before uploading it?

yes, I did. I could spend more time to do it better, but I decided not to. Part of the problem is the noise from the high ISO that I used. --WT

Noise? High ISO? How bad was the light? Or did you resort to the high ISO because of the slow lens? You should be able to still get a sharp photo at 1/60 of a sec. unless the wind is moving the branches.

All of the above. Light was dim, late winter day in Yosemite valley, plus slow lens, handheld. Actually, the original picture is pretty sharp. I can get make a sharper image from the original if I ever needed to. --WT

I thought the original would be sharp. I think the problem is the image the way it is presented in its form on the internet is not doing it justice. Much of the fine detail is lost. Maybe the image can be enhanced to show the detail a bit more but it would take a little work. I'm not sure if you realize that there is a quality (sharpness) loss when an image in digitally downsampled. There is also another degradation of the image when the JPEG file format is used due to compression.

I wouldn't worry about it as the image still looks good on the internet but in print form look even better.

Yes, of course. I don't worry too much about sharpness when I downsized and compress my 6MP images to show on the Internet. I played with different unsharp mask settings this morning on this image, and I was able to significantly improve the downsized image even at the 760 pixels max that I set for it. I didn't bother to upload another version, however. I was mainly interested in aesthetic impressions in this case anyway.

Thanks,

Warren
