I think we're both right - aren't we? Going up each stop of the f/stop scale the light is halved going down the scale it's two-fold. But I do think most people with a camera don't know the derivation of f/stop = lens focal length vs aperture area. But most know the relationship between f/stop, shutter and ISO/ASA.Fortune Cookie wrote:
I think anyone who is serious about photography understands that -- and that a one-stop difference, whether achieved by changing the aperture or by changing the shutter speed -- is a two-fold change in the amount of light reaching the exposure surface.
I packed it in about then too. I spent two evening with much needed bonding with my camera. For a SONY product there are some oversights. No remote max time exposure 30 sec. (RX-100i). I really should have worked with the 4AM green sky In Rockport - instead of moving to Bearskin I headed to Gloucester and the green sky had faded.Cape Ann Web wrote:
I was at Old Garden Beach. The aurora forecasts were showing continued weakening, so I packed it in around midnight. Another miss, lol.
On the evening news, I saw a series of 7 images of the eclipse that NASA released that included the ISS photobomb. I wish I could find that one.Da Man wrote:
