  • Thanks for the video. However, you said that you were going to cover effective reciprocal, but I didn't see it. What I'm assuming it means, and have often wondered and seen conflicting opinions on, is as follows: if I'm shooting with a 250mm lens with a camera with a crop factor of 1.6, then the effective reciprocal rule is actually 1/400 (250 x 1.6). Also, I'm assuming that means it will be a good shot for a STILL subject. Meaning, if I'm taking a picture of a male athlete in motion (lets assume 1/500 on average), I would need to add my baseline of 1/400 + the fast moving subject (1/500) and would require a shutter speed of 1/900 for a sharp photo. Do I have that right? thanks in advance for an answer.

  • I find this video isn't noob friendly at all and assumes you already know a bit about cameras. You jump straight into talking about focal lengths, shutter speeds, etc, etc. but what does all that mean to someone like me who knows absolutely nothing about photography terminology? If this is photography 101 shouldn't you start off with those simple basics??

  • shooting wildlife in low light, shutter speed suffers with low ISO. I shoot a canon 7d with L glass. Ex; an osprey flying by, the sun is still shining on the ground but VERY low, I'm in the shade. On manual, ISO up to 800, exposure is almost black. Go to shutter priority and drop the aperture and still almost black. The camera wants me to increase the ISO. I cannot get a high enough shutter speed without putting the ISO on auto, when I do It jumps right to 2500-3200. I'm getting a ton of noise. With this quality of gear I expect more, how do I get it? thanks in advance.

  • Thanks for sharing this excellent tutorial of photography technique! I've always heard of the "1/shutter speed" guideline, but I didn't know that there was a technical term for it. Also, the "Reciprocal Rule" term can be intuitively confused with "Exposure Reciprocity," which sounds similar…. but obviously very different.
