comment Incorrect exposed images when shooting sports
@Caleb - sometimes the action is pretty fast and clouds can move fast too - I missed shots because of moving clouds

comment Can a 2 mp camera produce a 2 mb sized file?
@MichaelClark - I very much doubt the asker old cellphone produces raw files, the only files you can get out of the phone are processed image files, so I think this answer is right

comment When should I consider an image sharp?
@mattdm - the question was about checking for degraded sharpness relative to when the equipment was new - this is a valid concern since things can get knocked out of calibration, I answered with some easy (except for the ruler, that I now deleted) tests the asker can run to see if the equipment really is damaged or if it's only fear and uncertainty, I really don't think I did anything bad (it's better then telling him "everything is fine, you are crazy"). I don't want to add to the "fear and uncertainty", I'll add a disclaimer at the top saying the equipment is probably fine

comment When should I consider an image sharp?
@mattdm - this is not a question about compering cameras, it's about quality degradation in the same camera - and sharpness is easiest to see in 100%, I agree about the 45deg ruler being hard to get right, I'll update the answer

comment Is there a way to delay shutter release when using a remote shutter, possibly with the aid of Magic Lantern?
The 550D has in-camera options for 2 seconds and 10 seconds delays, when you use a wired remote the camera will used those settings. I don't know about the IR remote or Magic Lantern

comment Does focus breathing make a lens slower when close focusing?
Rule of thumb: when in macro mode everything behaves differently

comment Is in-camera HDR and panorama better than post?
@feetwet - the current generation of inertia-sensor-based stitching is pretty mediocre (at least based on everything I downloaded to my phone) while the current generation of content-based stitching is amazingly good - I don't see any reason to care about the missing inertia data for at least a few years.

comment Solutions to Multiple 70D Connected to a single computer?
can't find anything that supports wifi, digiCamControl (digicamcontrol.com) and Breeze systems DSLR Remote Pro Multi-Camera (breezesys.com/MultiCamera/index.htm) both offer multiple camera controls but not wifi (according to the web site, never used any of them)

comment Should I expect better results from more expensive variable ND filters?
Why don't you get a fixed ND filter? a fixed ND filter will have less effect on the image because there's less glass and no polarization - and for the amount of money you are spending on a variable ND filter you should be able to get a set of reasonable quality fixed ND filters at different strengths

comment Desk pictures lighting setup
Can you tell us what equipment/budget you have? the answer for a system camera with $1000+ worth of flashes will be quite different than the answer for a point and shoot with only natural light

comment How do I get a consistent White Balance when shooting different color products?
@Rmano - well, "indecent light" does seem to belong in a different kind of web site

comment How to do jewellery photography with a telephoto lens?
@PhilipKendall - sorry, I'm not an expert in all the 18-55 versions, I was going by reputation and my own faulty memory, I fixed the answer.

comment Do Left and Right matter in how the photo is perceived?
@RussellMcMahon - you made me laugh - but I'm going to answer your comment seriously - I wrote only about LTR language audience, I suspect (but don't have anything to back it up so I didn't write it) that the reverse isn't true for RTL/vertical languages - but if it does - you can have the subject look slightly down/up or look/move toward one top/bottom corners

comment Do Left and Right matter in how the photo is perceived?
@mattdm - there is good research that show people scan pictures in reading direction but I can't find any credible scientific study about the feeling difference of LTR vs. RTL images

comment Why shutter is not closed by-default on mirrorless cameras as it's closed on film ones?
@BrianFunt - the sensor can't stop recording, light sensitive electronics remain light sensitive even when it's inconvenient, "electronic shutter" is implemented by reading the data while the sensor keeps recording, you either get low resolution (when reading the entire sensor at once) or strange artifacts with fast moving subjects (when reading line-by-line), your typical compact point-and-shoot is both low-res (compared to DSLR/mirrorless) and not typically used for high-speed subjects, high-end point and shoots usually have mechanical shutters

comment Why shutter is not closed by-default on mirrorless cameras as it's closed on film ones?
@BrianFunt - the shutter need to close when you finish taking a picture, when the shutter closes no more light is hitting the sensor so the camera can spend some time reading the data off the sensor without new light changing the data while it is being read

comment What is the best paint to use to make backdrops for studio photography with blown out white backgrounds, and dark black backgrounds
@yoshiserry in the past I've successfully used one $70 Chinese speedlight and a cream-ish off-white wall to create a white background image. the more expensive lights are better but you don't need that much light unless you need to overpower the sun or have a huge area to light. in a studio, photographing one or two people, a 3 or 4 speedlight kit will give you all the power you really need and a good 500 watt set (preferably with adjustable power) will give you all the extra power, speed and flexibility you will ever want.

comment Can using a reflector or external flash soften harsh natural light, or just fill in shadows?
@Morpho - this is not a problem, you can control the power and softness of the light by moving the reflector closer of farther from the model and by using a bigger or smaller reflector, it's all controllable and you should play around until you get the look you want - and you probably don't want balance, balanced light is boring, interesting light has direction and shadows and often color - and if you do want balance you don't do it in direct sunlight, you find some shade.

comment What are meaningful deciding factors when deciding between Canon 5D mark III vs mark II?
@Morpho - (cont from prev comment) ... the phase detect auto focus in the 5Dmk3 with a new lens is both fast and accurate, it focuses as well as contrast detection or very careful manual focus (the focusing mistake is too small to detect) - now the 5Dmk3 does not miss focus because of the camera technology limitations, but, this only translates to better images if: 1. you had a focusing problem to begin with (if you don't shoot with shallow DOF the old system is accurate enough), 2. you have good technique (photographer mistakes cause much larger error than camera mistakes)

comment What are meaningful deciding factors when deciding between Canon 5D mark III vs mark II?
@Morpho - phase detect auto focus systems are designed to be fast at the cost of being less accurate, the camera focuses at some range around the object the focus point is on and not exactly on that object, normally you don't notice it because it's close enough and less then your DOF - but if you have a very shallow DOF you can see your picture isn't properly focused (you tried to focus on the eye but it missed and either the tip of the nose or the ear is in sharpest focus) ...
