  • Thanks Ed. An added word on documenting vs going only for the striking photo: 1) it means I have an excuse to be out at the cliffs even on days when the light and perhaps the weather are awful--a ...
  • Hi Bassy, I missed that image when it was posted. Nice closeup. That bird looks quite different from what I see of peregrine falcons on the Oregon coast. Our juveniles tend to have blue eye-rings ...
  • Created discussions SX50: a tale of 3 peregrines
    When I first started photographing peregrines last year I was struck by their beauty and grace and I was trying to capture that. The sequence below shows how circumstances also moved me to turn my ...
  • Lyle, baby, you haven't a clue how to distinguish credible sources of information from bogus sources of bullpucky.
  • Who the heck says Lyle has one remaining neuron? Proof please. So far the evidence is against neurons there. Don
  • Wow, Murry! Quite nice colors and you're spot on about the light. It's not the only thing in photography but it is ahead of whatever is in second place. Happy shooting, Don
  • Hi Ed, Nice fall set! Thanks for sharing. Happy shooting, Don
  • Hi Ed, In many things in life folks make up their minds based on initial impressions and then backfill the logic. That can create some dissonance that gets in the way. Initial impressions caused a ...
  • Hi Chris, If I understand, your evaluation at 50% pixel magnification gives you two confounding issues combined: 1) the two images are compared at different image magnification (that is, you are ...
  • Replied in SX50 or SX60?
    Hi Jack, Your points and those from Steen Bay below are shared by me. I am turning my attention more toward whether the supposedly enhanced AF and IS are improvements that work well in practice. ...
  • Replied in SX50 or SX60?
    Hi Augustin, Thank you for pointing out pretty much exactly what I've been writing about: the rush to compare without the attention to detail in the comparison images. A quick look at the full ...
  • Hi Henry, Some good observations: I think you're saying that there may be a manufacturing/QC curve happening in addition to a learning curve for the photographer. I think we see the latter a lot ...
  • At the same magnification? How do you know? Did you do the real test of looking at the same image size for each image compared? Fairly? With what for your interpolation? Or, did you just take the ...
  • Now we're going off a bit. A very good picture from an SX60 may be as good as a very good photo from an SX50. I would say that the jury is still out because almost no one (am I alone here??) has ...
  • Hi Dennis, Great point! For me, waiting for interesting action can be many minutes to an hour. Then it's so annoying to think the bird has started and to trigger a burst only to have the ...
  • Replied in SX50 or SX60?
    Yup, that's what they all say--without regard to the idea that they're making the comparisons at different image magnifications because it is just so simple to make them at "100%." Happy shooting, Don
  • And I bet you've not found a properly designed comparison that shows both images at the same image zoom. That includes some way of controlling for interpolation artifacts when scaling to be at the ...
  • Replied in SX50 or SX60?
    The SX60 image is 33% more pixels than the SX50. This means that the image is 1.15 X larger on a side than the SX50. This means that you would either have to compare the SX50 image scaled ...
  • Thanks for your kind comments Ed, Darla, Mario, John and Augustin. Unfortunately, that may be my last shot of the Yaquina Head Light for a few months because they've started a big project of ...
  • Lee Jay, Possibly. I read his complaint as thinking that only Auto mode was available and that Auto mode would pick ISO 400-500. I've done hundreds of HQBurst mode bursts with the SX50 and it is ...
