P, A, S, or M - the fundamental choice. For years, I have been a A kind of guy, perhaps because I come from a Leica background where the camera has no way to set the aperture. So with the Leica M8.2, I would choose an ISO, usually 200 for outdoors and 800 for indoors, and I would choose an aperture for best compromise in DOF and camera-selected shutter speed. So I did the same with my A7ii for many months. Always raw + jpg. But a post by Lucille a few weeks ago turned me upside down. She mentioned that she likes Sony jpg ( all of her images on this site up to that time were camera-generated jpg ) and she always shoots full manual. So before my trip to Alaska I decided to change things up for me a little. I switched to extrafine jpg instead of raw + jpg, and I switched to M. But I decided to let the camera choose ISO, within my predefined limits. From a few months of experience, I knew that I am happy with images from ISO 100 to 3200. So I let Sony, the sensor experts, choose my ISO with Auto ISO. Then, for each shot, I choose shutter speed to keep motion blur under control and aperture for DOF and lens drawing considerations. I keep my eye on the ISO indicator to make sure it is not blinking. Then just focus, frame and release shutter. I have been pleased with the results. There are more keepers. What mode do you use? Why? What results do you get?
