math guy's recent activity

  • At first I didn't see the chain/wire in this one, and I thought "Wow, now that's a strong dude!" After I looked more closely, I thought "Wow, that's a well-timed shot!"
  • Now that's a great baby announcement. Very well done. Congratulations!
  • Replied in Winter Storm
    Nice set there. "Winter Road" is my favorite all-around, but I do like the texture of the falling snow in "On Lookout." I'm in central PA, and the storm is just now coming in. Unfortunately, the ...
  • Replied in Cole Run Falls
    It's funny that you posted this shot when you did. I live a few hours away, and just last Friday someone was telling me about these falls. Nice shot!
  • I don't mind at all, and I think you're right about the crops. To be honest, I took those over four years ago and had pretty much forgotten about them. Glad you asked about them to prompt me to ...
  • I dug some out an put 'em in an album in my gallery here: http://www.dpreview.com/galleries/5916423393/albums/lake-placid-murals Some of these are panoramas, and I didn't really shoot them well ...
  • Love the colors! Reminds of Lake Placid in central Florida, which has over 40 murals on buildings all across town.
  • Yeah, this is the time of year I miss it down there. I moved away from Alabama a while back because I didn't like 90-degree temps for 5 or 6 months a year. The older I get, though, the less I like ...
  • I really like number 5 -- excellent composition!
  • Beautiful series! I especially like the reflection in the shot of Pemaquid. That's my favorite lighthouse along the Maine coastline.
  • Wow -- that last one is a great shot!!
  • I agree with the recommendation of the 55-300. Eventually you'll probably want to upgrade to an f/2.8 zoom to get better subject separation. But that will run in the neighborhood of $700+. The ...
  • You've already gotten some good advice. I'll just add a few things. I shoot with a K-x also, and I've noticed that if the batteries are getting low it has a tendency to mis-meter. So the first ...
  • I'm glad you brought it up, though, as I had not previously noticed that the K-3 and K-S1 sensors were smaller. Besides, I think folks here know you well enough to know you aren't trying to stir up ...
  • Hi, Robert. Good to hear from you. I do understand the basic idea of pixel density and that more doesn't always mean better. But there is a sense in which megapixels affect the way the image ...
  • Yeah, that's pretty much what I was trying to convey. I wasn't really trying to make any claims about one sensor being superior to another, but I think that must be the way it came across to some ...
  • Only by about 1.5% (366.6 sq mm vs. 372.09 sq mm) -- not a significant difference in my opinion. But admittedly, I don't understand the science of camera sensors as well as a lot of others on this ...
  • It's just a visual comparison of how different megapixel sensors compare. Because the stated sizes of cameras' megapixels are areas (the product of two dimensions), it's not always easy to picture ...
  • Created discussions K-S1 resolution comparisons
    Here are some visual comparisons of the max resolution of the new K-S1 to those of recent Pentax DSLRs (going back to K-7). The K-S1 is the green one in all images. 5472 x 3648 vs. 6016 x 4000 5472 ...
  • Really like that church shot!
