About me:

I want to understand the in-depth fundamentals to inform my ability to make engaging images.

GeorgianBay1939's recent activity

  • Snip I have a variant of PD which inhibits my mobilty.  I also have been fighting Ca for 10 years with 15 operations.  I am good til my next "inspection" on 2017.05.30.  So I walk with a ski pole ...
  • It may be strange but it is also a lot of fun. We all have different life experiences and (hopefully) are still learning (and changing). So we all have different views of scenes, which change with ...
  • As a ex-downhill skier and recent photographer of snow , I much prefer your image.   The  flying snow, especially around the uphill pole plant and ski tips,  gives the whole image some dynamic ...
  • While I agree with the comments in your first paragraph, it seems that the Heliskier Dan  hasn't had sufficient experience with shooting snow in flat light to demonstrate the capabilities of the ...
  • RR22:
    I am usually interested in seeing how much headroom* I have in the histogram or the zebra stripes when in the Liveview EVF, (or blinkies when chimping.)
    informed by an in-camera JPEG.
    So I...

  • EE22: good examples of exposing for snow structure/texture. Why does Dan's imagery have almost no snow texture, albeit in flat light. I could understand if he were shooting jpegs, depending on a...

  • Yeah, I am not a commercial photographer so for a decade I've been playing with photography only for the fun of it. I get my jollies by using the camera as a tool to learn more about my visual ...
  • That is a great thread.  I remember it quite well, but not well enough to "operationalize" it.  I will go through it again.... after I process a big bunch of raw files that I shot today, the first ...
  • SNIP Flattery will not work with him or with me!   But a good try though. I enjoyed several of your images, including the above, with the subject probably enjoying a last drag on the cig before ...
  • Ok, thanks.  I think that I have it now. That is reassuring.  Are those rules in the ISO standard? What are the main factors driving Auto -ISO?    For example my rules for setting ISO when shooting ...
  • The above contains many of your images in response to joger's request to you: " I agree with the lenses - for the rest I am lost - please post some of your best images and give me an idea which ...
  • Thanks. Can you give us the link to bobn2's notes that you summarize above. I don't think that I understand your last two sentences above. If I ETTR using the histo and blinkies, I use spot ...
  • Again, you are doing your side-step dance. Did you find the comparison between Fred's and Mike's potato fields useful in understanding exposure in Silberstein's "light-darts" exposition?   That is ...
  • I honestly don't know. We might be right!  I've been called worse. I usually shoot raw ETTR using zebras (set at 105%), with a bracket of -2/3, 0, +2/3, spot metered with AELock, at base ISO if ...
  • SNIP Be careful with this: Be careful that you do not get side tracked by many  articles in popular magazines, the internet and by 'experts' who will try to convince you that Exposure (photography) ...
  • I think we are comparing two identical scenes. If the scenes are different then both the exposure, H(t) and the total light, Q(v) can be different. If FingerPainter said "For a given exposure, in a ...
  • I agree with you. I had jumped from Exposure, H(v) (in lumen-sec per square meter) to Luminous Energy, Q(v) (in lumen-sec) " collected ". I should have used the term "at the sensor" or "incident on ...
  • Yes. This student says, "The total amount of light energy, Q(v), in lumen-seconds, collected by a sensor of effective area, A, for a time, t, is given by the product of [Exposure, (H(v) in Lux-sec ...
  • Uh, oh! Does this mean that he doesn't yet get it. Where does "on a point on the surface" come from? Can you give me a reference? Or are you just being "mathematical" here? This is the conventional ...
  • Yes, it is. It is exactly what is said here without the use of the words "time integration": In photography , exposure is the amount of light per unit area (the image plane illuminance times the ...
