  • The one on the right is much worse: David
  • I'm hardly an expert in these matters, but Machu Picchu is fairly small and a single day should be sufficient. Start early. We got in line for the bus at 6 am, and there was already a line about 6 ...
  • I thought I remembered how to display a difference between 2 images in PSE, but no. However, one thing that struck me about the DPR compression is it's asymmetry. Red is strongly compressed: Green ...
  • Pbase still saves and allows downloads of the original file: Other image-sharing sites may also - I don't use any other than Pbase. David
  • Ted- Do you compare by visual inspection, subtracting one image from another, or do you use some other method? David
  • It looks like DPR is doing some compression. I downloaded the file to see: You can see that the uploaded file was 27.3 MB and the downloaded one was 8 MB. At 400%, the differences are evident, but ...
  • We saw a demonstration how the local weavers made the red dye from insects. Pretty amazing. David
  • Hi Mike- There's been some grousing in the past about big files - apparently everyone does not have 100 MBPS download speeds. :-) Here's the flower blanket at full rez (27 MB) David
  • Created photo thread Machu Picchu and Cusco
    This was not primarily a photo-trip, but I brought along my DP2M. These are all half-size images. Above Cusco, which was the capital of the Inca Empire Small settlement along the river fog starting ...
  • put the original on some share point, and post the photo here. I looked at this problem some time ago, and the degradation was very minimal. You had to carefully examine the before and after to see ...
  • I'm sorry Ted, I don't see the point. These two examples are the same image; the second has increased micro-contrast. You've up-rezzed a (presumably) full size Merrill image to 6653 x 4435 and ...
  • I don't want to overwhelm you with a lot of technical jargon, but you have a fantastic camera for flower close-ups and you will eventually want to learn all of this. This next image is 2 images ...
  • I'm not sure what question you are asking. At f/1.8 or f/2, a flower closeup will show only a portion of the flower in focus, so what you posted seems exactly as expected. (All your posted images ...
  • Three-shot, hand-held, half-size. Taken from partway up Mt. Dana. On the right, Saddlebag Lake. Moving left, the high point is Mt. Conness, which has a huge summit plateau and then a narrow (and ...
  • Nice shots. I like 'dust blowing in the wind' best. (There is a dust spot right next to the Moon.) I like the purple one, too. David
  • Created discussion thread Yosemite - it's not all smoke-shrouded
    I was up in northern Yosemite for 2 days. In the afternoon, it got pretty smokey from the fires further south, but mornings were clear: Somebody put in a lot of effort to build these cairns every ...
  • I, too, don't quite understand what you are asking. I agree with all the suggestions that gordonpritchard made. You can manually develop a single image (say the underexposed one) to lift the ...
  • Nice sharp image. But it looks a bit blue... David
  • I processed your originals in PhotoMatix in both 'natural' (not natural at all) mode: And 'photographic mode': I didn't get that cloud band you saw. However, the near vegetation (in the corners) ...
  • Again, I think that the 2X extender does not gain you any resolution, and the slower f/13 required makes for a noisier image. Here's a comparison of your result (1200 mm f/13, 1/100th sec) on left, ...
