I've been a software developer for a lot longer than I'm willing to admit. My current interests are C++ and Python on Windows, but I've been known to dabble in Linux and I try to be language agnostic when I can.

comment Is the anti alias filter really a blurring filter?
@joojaa the answer is complex. As noted by this answer, only half of the problem is the anti-aliasing filter, the other is the Bayer filter demosaicing. The anti-alias will send some of the information that should have gone into one color pixel into a different color pixel instead. Modern demosaic filters are not simple beasts, and I doubt their response can be modeled consistently.

comment Is the anti alias filter really a blurring filter?
@RogerKrueger you can theoretically get full resolution if the input is monochrome, the output doesn't matter. I think many modern de-Bayering filters attempt to approach this ideal, but I don't know how close they come.

comment How can I compare 'super-zoom' lenses to make up my mind which one I should buy?
Beware that there are different aspects to image quality, there's no easy way to rank lenses unequivocally. And there are other things to consider, such as speed (F-stops), range, and close focus abilities.

comment What is the 'Golden Ratio' and why is it better than the 'Rule of Thirds?'
@Julian 1/1.61 is approximately 0.62, which is the proportion given in the answer.

comment Does the right calibration temperature for my monitor depend on season?
The appropriate white point is based on the color of the light in the room where you'll be viewing the picture, not on any conditions where the picture was taken.

comment Does the right calibration temperature for my monitor depend on season?
@mattdm there's no seasonal effect. The time of day might matter, but not the time of year.

comment How do I fix a dog's wrong colored eyes in flash photos?
Older versions of Paint Shop Pro were unique in having red-eye removal that works on pet eyes.

comment Should I be shooting in RAW even though I'm a beginner that doesn't know how to retouch photos yet?
@Designer023 thinking before each shot does give you better outcomes, but only if you have enough experience to do the right kind of thinking. See the story at the beginning of blog.codinghorror.com/quantity-always-trumps-quality

comment Should I use JPG or TIFF for high-quality prints?
Your sample link didn't work for me. And is the damage you see in JPEG caused by artifacts, or is it just due to being an 8-bit format?

Don't forget the polarizing filter.
