comment Is the Carl Zeiss 16-80mm good enough for night shots?
A77i is goodish at ISO 800 , bearable at 1600 and usable at 2400 or 3200 if you value a usable image over noise. ie 800 would be daytime max if you cared somewhat. More at night may be OK. f/1.8 is reasonably useful in a city with shop lights, good street lighting etc if you take great care. f/2.8 about as good (1.8/2.8)^2 =~ 1/3 the light. f/3.5 = 4x less light than f/1.8 = 2 stops is getting reasonably marginal.Camera can be braced and you can Ninja breathe but aany subject movement may reduce photos to more art-statements than records. Above that anything can work sometimes.

comment How does a 16-300mm f/3.5-6.3 lens differ from a 50mm f/1.8?
... Now try this with the 16-300mm lens set to 50mm at largest aperture (smallest f number) you can achieve at that focal length (may be 3.5, maybe slightly higher). Compare results. | Keep them both - both have uses which will make you very pleased that you own them.

Adding to the rest: To achieve the same quality of image (various measures that you can achieve with the f/1.8g prime lens with a zoom/telephoto lens you would have to pay many times more. The prime will give you a peek into image quality levels unachievable with the other lens. Try taking a portrait at f/1.8, not too close to subject, background some distance behind subject - maybe bushes etc. Focus carefully on area of face of most interest. Try focus on eyes to start. Look at result on a screen at 100% so you can see fine detail. How sharp is hair etc at focus point and elsewhere? ....

comment Sony A7s ii possible overvoltage
It won't address your current problem sadly, and you essentially now know this, but it's still worth noting. | When using equipment of high value with an external power supply it should NEVER be possible to "accidentally" supply excessive voltage or to connect the supply incorrectly. Ideally protective circuits should be used to ensure that an out of spec power supply will not cause problems. || If you are lucky you may have damaged only the voltage conversion and power supply circuitry in the camera but it is by no means certain that this is the case.

comment How can I automatically apply smart cropping to hundreds of coin photos?
It's interesting to see here and in other groups that old hand and/or admins choose to downvote for reasons which seem (to me) to be well outside the downvoting guidelines. On past occasions such actions have been specifically "frowned on" by admins but now seem relatively common.

@dpollitt Vanishingly few downvotes can be explained by looking at the edit history and there is no reason that people would expect that this would be a standard way of telling why downvoting had occurred. I'm well aware that people are not obliged to make it known why they downvoted but it is far more useful (and relaxing :-) ) when people do.

comment How do I shoot a self-portrait with a clear white background at home?
As inkista says, much brighter light on a white background BUT you can use an editor to replace a colour within a certain range with another colour. If the chosen background colour range does not occur anywhere in the desired image then the background can be replaced at will.

comment How can I use Photoshop's filter to remove motion blur without getting a doubled-image effect?
I'm trying to understand your question. IF the large image is the unprocessed original and the small image is sharpened outp[ut then the result is unsurprising as the double effect is in the large image, which I understand you to say is the original. || My question was: If the large image is the original, when you sharpen the whole image, do you get a multiple image anywhere except in the "text" at the top? If so, can you give an example?

.... (4) If the backdrop is over another surface with a small gap between the two you may get shadow and/or projection of the front layer on the rear. || Examination of the majority of the image suggests that the effect is pronounced with the top text and much less so for the poeple. With the people it is far harder to tell due to shape/contrast/edges etc. | How does the rest of the image seen when "sharpened".

comment How can I use Photoshop's filter to remove motion blur without getting a doubled-image effect?
This can happen for several reasons. (1) THere really were two images - a possibility here as the effect is FAR less obvious further down and may be due there to other factors. (2) Flash and background lighting give different images - if the camera was stationary over much of the exposure but moving or had moved when the flash fired you may get two exposures. This is especially common when flash is used but background light can supply much of the exposure. If there is a "party strobe" working this can contribute. {3) Similar to 2. but STiLL-move-STILL exposure..... -> contd ...

Thelink above is to an image which has two overlapping exposures in it - is that the result AFTER deblurring? If so, can you post the original before deblurring. mIf the link IS to a pre deblurring version then there are two distinct images there.

comment Is there a Lightroom feature for ranking images collaboratively?
You could use something as mundane as Facebook. A private album can allow access only to desired people. "Likes" could be used (only 1 per photo) and/or the comments added could contain rankings and/or comments. There are probably API interfaces available that allow these to be read under program control.

comment Why do the same poses seem stupid on my pictures, but good from pro photographers?
I came across the (to me) most unnatural looking pose in a photo today. wrt your question I followed the link to this Pinterest page containing many professionally and strangely posed people - bicycle theme. Some somewhat NSFW - in some cases (eg I'd be happy to have my wife see this screen open on my PC, but she may or may not ask why). The point is - looking at photos like this may persuade you that professional poses can look rather silly if you stop and think about them and/or that yours probably look similar - for better or worse.

Related: .... Two people together are more likely to agree to be photographed than one person by themself. If one is reticent you can often "instruct" th other person to persuade them to have a joint photo. | Interestingly, in some situations a stranger is willing to allow a dual "selfie" but not an individual shot.
