comment Why do some umbrellas have black cover instead of silver?
the cover indeed is on the convex side. What I meant is that when using umbrella in reflective mode, part of the light bounces right away on first hitting the white material on concave side, but almost half goes through and is possibly lost. Using a silver cover on the convex side, facing the white fabric would catch this light and bounce it back to the translucent white, where it would shine trhough back to the concave side, adding up to the light that bounced directly, saving you almost a stop of light from your source.

comment If I swallowed my SD Card would it be readable when it emerged?
I've seen a lot of suggestions about micro sd cards. Why not having a big piece of chewing gum and sticking the microSD in there. IF you swallowed it, it would lessen chances of sticking in throat and would reduce exposure to acid, but you may manage to escape without having to "wait", specially if you do the swap with a card full of "innocent" picts.

comment What kind of earplugs are best for concert photography?
I have successfully used a pair of earplugs from my phone to protect my hearing while usind a reallly noisy grinder (I know it's not the same) in a confined comfined workspace. They were not plugged to the phone nor a music player. They were in ear type, of the kind that are "noise blocking" with a mushrom-like rubber fitting. I'm not suggesting these for long term use, but they can serve in an emergency if you have them in hand.

comment How to record the viewfinder while shooting?
I performed the experiment using an Olympus XZ-1 on the viewfinder of a Canon 50D. The Olympus could get an understandable image but it was not wide enough to cover the full viewfinder's image plus the exposure meter and the outer indicators. Also tried with a cell phone's camera, but it had an even narrower angle of view.

comment Why don't most cameras store filenames based on date and time?
The Brand Olympus has a simple system: it usually starts its names with a 'P' or '_'(don't remember what means but it's related to colorspace), then a digit for the month: 1,2,3,4,5,6,7,8,9,A,B,C, two digits for the day and four other digits for correlative. Thus, file PC083651 was shot on December 8th. It is indeed VERY useful and at least I have never had a problem. It's only odd if you shot during Dec 31 midnight, because "older" file suddenly gets on top of the alphabetically ordered list. Maybe they have a patent and it keeps the rest from doing it.

comment Program to remove thin strip from inner part of image
This particular task is actually performable even in Windows' Paint. It has selection and move tools.

comment How do I fix a dog's wrong colored eyes in flash photos?
Giving a twist to your idea: A flashgun that has slave mode (the kind that "detects" the firing of any other flash) can be triggered without a transmitter, you just have to use a small cardboard or small mirror to redirect camera's flash towards the flashgun. This trick is extremely helpful if your camera does not have a hotshoe, like a P&S for example.

comment How do I fix a dog's wrong colored eyes in flash photos?
It doesn't work because of the logic of the feature. In Humans it works because camera's beam or pre-flash causes our natural reflexes to contract the pupil, hence reducing the efect of flash reflection. Animals have different sensitivities to light and different pupil sizes/shapes. A camera's red eye reduction may not be strong enough to stimulate an animal's pupil contraction reflex. I have seen that cats are barely anoyed at night if I suddenly turn on a car's headlamp in front of them, they can easily stare at it, while I can't, until afer a while...

comment Is it possible to obtain portraits free of charge in exchange for letting the photograper use the photos for his/her book?
Interesting concept. A short explanation on this site plus the reference to the external source would have made such a better answer.

comment Is it possible to obtain portraits free of charge in exchange for letting the photograper use the photos for his/her book?
Even though the question as it is now is a bit difficult to read and understand properly, It has led me to a concept I did not now before, so I think it is a good question in that aspect. The downvoters should have stated why they didn't like the question. Agreed the question needs to be edited.

comment How to capture fog movement?
Are you sure the only thing moving in your pictures is the fog? What do you want to achieve? droplet trails?

comment Why does my memory only sometimes show my images?
AS you mention an iPad: IOS and its relatives have a funny way of deleting files, they are not deleted but moved to a "hidden" directory, but other devices just recognize those as valid files, so they don't display the expected free space. If you have a windows computer, configure it to show hidden files and you'll be able to see all the card's contents. Make a safe copy and then format the card either on that computer or in your camera. Every time you "empty" your card with mac's software, format it in your camera.

comment How can I make my own film scanner using a DSLR camera?
I have tried some of these. Computer monitor is bad idea if you put the film too close to the screen, pixels will show up, and at macro setigns, they are pretty big. Flash on the other hand, can be WAY too bright if used directly. For both you'll need light modifiers (difusers or reducers, depending wich one you use)

comment White balance adjustment using gray card
I can't answer for the gray card part, but I frequently shot in forests. Personally, I use one of camera's presets acording to what the sky is: Sunlight, Overcast (Or Shade in some situations, like way after the sunset of before sunrise) My preferred is Sunlight(5300-5500k). Also, set low contrast (0 or -1 in a camera that allows -2 to +2) and saturation up (in 0 or +1) These settings work best for me, as they give me "neutral" looking images that I can easily adjust in post. I think that records correctly the color casts, so I can compensate adequately after the fact.

comment Is this a reflection in my photo?
Definitely, it is an aircraft. I have made such shots intentionally and that ir the precise result. The same would happen with a long exposure of a moving car that is using it's turn signals! ;)

comment Using flash with Aperture Priority or Shutter Priority gives me a white image - why?
I suggest to metter a scene with your camera with the flash off (detached) and note the values calculated by the camera. Repeat wit the flash activated. Do the values change? If not, then your camera is somehow unaware that there will be flash lighting the scene.

comment Using flash with Aperture Priority or Shutter Priority gives me a white image - why?
Some Body/Flash combinations do not work so well together. I have never had a camera that correctly compensates flash usage with semi automatic modes, I've always had to trick the camera into what I want. Maybe this is your case too.

comment Which cameras have built-in HDR?
I've just read that the Olympus XZ-2 has HDR mode too. It's a compact camera.

comment How can I get a good HDR image from a single RAW file?
+1 for revealing the detail it alrady is in the single image. I was recently experimenting to rescue an image of a person under a tree's shadow with a bright sky behind her. I tried both, Photoshop's HDR, And curve editor in Canon Photo Pro. I like the Canon version much more than the HDR version because it had better saturation, more natural color and avoided the halos.
