• Yes, See http://www.dpreview.com/forums/post/57226633 , Where I make a comment about Alex Cooke. Better than most.  Still gives a misleading view of ISO as analog gain, but he is not alone.  It ...
• 4 vertices, 6 edges and 4 triangular faces. If we put f/, SS, ISO, L on vertices, A, B, C, D any triplet will define a triangular face and 3 edges. Triangle ABC = Brightness Triangle ABD = Exposure ...
• Replied in Yikes!!!
P is too advanced for me.   This is the Mode that I use:
• Replied in Yikes!!!
Hi Jeff! Gollywop is right. I need to be more explicit when I try to demonstrate the ridiculousness of the situation by posting extreme examples of crap . :-) It is a form of argument similar to re ...
• FINALLY, EFB!!!!! A solution to all of this hectoring : http://www.photographyforblogs.com/exposure-for-beginners/ " – the aperture is the size of the window, or the gap between the curtains – the ...
• We get a lot of snow each winter.  Sometimes (sunrise and sunset) light reflecting off of the snow in the forest can be quite nice.  I've been lucky to get quite a few over each winter.  I also ...
• VERY nicely stated. You are obviously one of those rare teacher/artists who brings learners to the concept, applies it, then shows its limits and MOVES ON to the next steps in the journey. You do a ...
• Of course not. But it is still taught in photo 101 to unsuspecting students.   And it forms the fundamental for lots of folks who do not discriminate between brightness and Exposure (photography). No.
• Interesting verb. Here's one from my blog taken a couple of weeks ago: Winter sunset in Shawanaga Reserve, Ontario (Sunset 21:58 GMT, 15 minutes later than above) View: original size Interesting ...
• Yes. That is the case as it should be. Take the case of "initially appears to bright" as often happens when putting more light on the sensor than indicated by meter. In other words you have ...
• I don't use it either. When I am shooting A(perture) priority, I'll often shoot at acceptable SS and use post processing to brighten images. I guess that is one of the advantages of shooting raw. ...
• Thank you. Yes.  And so is context. For a beginner, coming into this hobby is heavily challenged by the misuse of terminology.  The experienced photographer knows when the author writes "aperture" ...
• Replied in Sunny 16!
I think that the interchangeable use of brightness and exposure is the source of a lot of confusion and error. Exposure vs Brightening is a good thing to read.
• Thank you! Although that is well outside of my limited knowledge. The concept of reciprocity seems embedded in the definition of EV .  I suspect that other factors affect digital systems when ...
• Nice!
• I do not see how Exposure (photography) can be varied in post processing.  Choosing EV (f/, ss) determines Exposure for a given scene Luminance, L.  Maintaining constant Exposure by keeping the ...
• I've used Lightroom (now 5.6) for about 7-8 years  (Panny Micro 4/3 and FZ1000), on a high end (2.7 GHz Intel i7; 16 GB 1600 MHz DDR3; 750 GB SSD) MacBookPro with 24" (Dell 2410 Monitor) and like it. ...
• You?  Or "some"?  Intellectual dishonesty brings out the best in me. That is the second time you've used that phrase.  Come on, a bit of creativity please. Why in the heck would you ask that? Yeah ...
• Who? You?   :-D ___________________________ Nobody seems to be engaging with the relationship between the ET and the Exposure Metering Equation, indicating that: Everyone's asleep. or It's trivial. or
• Ah, don't be afraid.  I just adjust my level to that of the conversation. By the way, if you are going to use big words like supercilious you should learn to use them properly.   You could use that ...
