I have a question about Polarr - from my reading it cannot handle RAW or DNG files, unlike Snapseed - is that correct?
So I gather you are shooting jpgs with your Sony RX10iv? Is that what you are referring as " letting the camera do everything it does well, so that your are free to see and compose the images"?
How does the Sony camera perform for birds in flight for you? I notice that many of your bird images are perched.
I don't have much success with mine for bifs. But shooting hand held 600mm is always tough no matter what tool you use. Maybe a gimbel mount might help me some.
My wife and I both own and occasionally use our Sony RX10iv's, but in our hands we still use larger, heavier, more cumbersome tools most of the time. At my age, I sure would like to use lighter tools, if I could.
The high frame rate of the RX10iv is amazing - I was able to shoot panos of the Blue Angels in flight with it
In brighter light, the Sony RX10iv can produce stellar images. How do you find it does in low light, before sunrise, say or 15-20 minutes after sunset?
