comment Lightroom - Vivid faces effect
It's [colloquially] called the "Dave Hill Effect", or at least it used to be, and you achieve it in the studio, not in Lightroom. See this question for more info: photo.stackexchange.com/questions/4710/…

comment How can I further decrease the exposure in a studio environment?
Twice the distance is 1/4 of the light, which makes this a very effective method to reduce the light level.

comment Does the size of blower matter to clean the sensor of the camera?
It's not the size of the blower, it's what you do with it that counts.

Put the camera on a self timer and leave the room ;)

comment How weatherproof is an average modern lens?
@MichaelClark A better way to phrase the question might be: "How weatherproof are modern lenses like the Panasonic 14-140mm?"

comment How can I target a specific size in megabytes when saving a JPEG in Photoshop?
@PhilipKendall If you read the whole answer it's clear ths is referring to minimum filesizes as being a meaningless measure.

comment How can I target a specific size in megabytes when saving a JPEG in Photoshop?
Great answer overall, but to be pedantic the statement "There is no way you could produce a 20mb file from eg. a plain white image, no matter the dimensions" is not true. JPEG divides the image up into 8x8 or (16x16) blocks for compression. It has to store some data per block even if there's no detail. The maximum dimensions supported by the JPEG format are 2^16 - 1. Creating a 65535 x 65535 plain white image in Photoshop and saving as a JPEG resulted in a 272MB file. You could go even larger using the progressive option, but I didn't have enough memory available to perform that operation!

comment Why doesn't a drastic change in aperture seem to have an effect on this city skyline photo?
Note that the calculator you've linked to by default gives values for what appears to be in focus when viewing a small print. If you view the image at 100% on a computer screen the depth that appears to be in focus will be much smaller.

comment What kind of lens is typically used for these type of night street shots?
Those shots would look very different with a telephoto lens, there wouldn't be nearly as much content in the background, to get that specific look you need a wide-ish ultrafast lens and a full frame DSLR (or larger format).

comment How would an experienced photographer have taken this shot of a man selling old stuff in a city market?
A "pro" is someone for whom photography is their primary source of income...

comment What kind of lens is typically used for these type of night street shots?
@juztroublez it would only be "equal" in terms of angle of view, not in other factors, such as depth of field or background blur. See this question: photo.stackexchange.com/questions/22671/…

Almost certainly not a zoom, given the depth of field, I think you're looking at a 50mm f/1.4 here.
