There isn't really a substitute for trying it and seeing for yourself. "Dusk" can be anywhere from near golden hour conditions when Auto will do great to almost dark where a night time mode will do better. The exact settings and conditions can vary greatly from phone to phone and day to day. If the image is coming out dark or noisy, try switching to a ...


To fix this, you need to decompose your image to RGB channels separately. R and G channels are vertically shifted from B channel by 5 pixels each. You need to align these channels vertically. For example I have shifted red channel 10 pixels and green channel 5 pixels from the blue channel. Here is the result with comparison : Shifted one Corrected one ...


Corrections on your assumptions: the A6000 and NX300 have a larger APS-C sensor. The crop factor for 1" (aka CX format) is roughly 2.7x, while APS-C is 1.5x. 4/3" (or four-thirds) is 2x. And the lens on the RX-100 is actually 8.8-25.7mm f/1.8-2.8 lens, but the 2.7x "crop factor" gives it the "film equivalence" of a 24-70 lens--which only means the angle ...


Those sensors are not nearly the same size: RX100 sensor measures 13.2 X 8.8mm. A6000 sensor measures 23.5 X 15.6mm That's 116.16^2 mm versus 366.6^2 mm. Just over three RX100 sensors can fit on the A6000 sensor! The difference is very substantial depending upon your use and shooting environment.


You can obtain lossless optimization (based on optimizing the Huffman tables). The utility jpegoptim provides this algorithm. Install it with (on debian): apt-get install jpegoptim To run a simulation (no action mode): jpegoptim -n -p dsc07844.jpg returns: dsc07844.jpg 3872x2592 24bit Exif [OK] 3057132 --> 2518805 bytes (17.61%), optimized. To ...
