Great to see some more positive feedback on the camera since the updates!
What resolution/mode are people finding best for general point and shoot? Auto or 3:4 (if so, with or without 108MP)?
Also, hoping for a bit of advice on the best ratio and mode to use in the following scenarios:
- Under artificial light indoors
- In low light
- Capturing movement without it being one big blurry mess (I tried taking a few of my dogs whilst they were running in the park and couldn't get any focus or features at all)
I don't use Samsung, so can't speak to any of their auto modes and other algorithmic tricks (I prefer manual mode regardless). In general, I would stick with the pixel binned 12MP resolution at 4:3 on the main sensor.
More pixels doesn't always mean better quality, and can hurt quality with such extreme counts. On my LG V60, the binned 16MP images are great, but the 64MP non-binned images are a noisy mess. Binned images effectively give each pixel 9x the amount of light gathering area (your camera uses a 3x3 arrangement), which translates to better low light performance and less noise. The native resolution is a 4:3 ratio, so I would stick with it. If you choose anything else, the software is automatically cropping the native resolution to match. I would rather capture everything the sensor can, then crop if necessary during editing. This gives you more flexibility both in actually capturing fast action in the first place, and then how to adjust composition with cropping.
I would stick to those options across the board, in all situations. There may be times you'll want to stray from that, such as needing the wide angle in a tight location or the 108MP option for capturing Bigfoot at a distance, but those will be the exception and not the rule for most people. If you actually need to switch it up, by all means do so. It's just been my experience that the secondary cameras tend to have worse optics that translates into low quality images, or the manufacturer is only prolonging the spec war that has little to do with reality.
For capturing your dogs, that would need great lighting to start with. If the sun is obscured or low in the sky, you'll have to start ramping up the ISO to maintain a workable shutter speed. Auto mode may not adjust this properly (remember, it was programmed by some random person you've never met, much less one that knows what you are trying to accomplish), and you would either need to use something like a sports mode or use manual mode. The problem is on such small sensors, ISO noise becomes problematic quickly. That means in less than ideal lighting, ramping the ISO up can easily cause you to lose the fine details like fur textures. Unfortunately this is needed to freeze the action while still being properly exposed.
Something else you could try is setting ISO a little lower but keeping the desired exposure time, which purposely creates a slightly dark image. Then edit that with a decent program to increase the exposure levels. It may not be the best option, but can work in a pinch if you already have a high ISO but it's still not bright enough.
