comment Handicapped shooter needs remote view finder display
Try Helicon Remote. It's an app for tablets. I can perform autofocus and control amost every camera parameter. It requires a USB cable though. The only drawback is that the free app does not let you shoot in RAW, the pro version is supposed to.

comment How many pixels in a megapixel?
As far as I understand, it is not that THE SAME 4 pixels are interpolated but EACH PHOTOSITE is used 4 times to calculate the color value of the 4 neighbouring pixels in the final image. (exept the photosites in the border of the sensor).

comment How much should an amateur charge for a portrait session?
Guess the cost of rental of equipment + (minimum wage fee per hour * hours of shooting) is a more realistic formula. Assuming equipment is camera, lens, and computer to copy the jpeg files to a CD or DVD for a set of digital pictures with no editting and taken without any particular skill.

comment How much should an amateur charge for a portrait session?
@chills42: I think your example lacks a very important part of the pricing: Honoraries. All the things you listed are correct, but somebody else may have the same excat equipment and other costs, but the final product won't be the same. Your time and the preparation you've had that allows you to generate the output you do is what adds value to the product.

comment What is the best way to auto crop bulk images?
I'm almost sure that clutter, noise or similar in the "background" is actually the cause for the scanner software failing to auto-crop some of the images in the first place, thus almost any automatic tool for the task may face similar dificulties.

comment Exporting jpg files from Lightroom without develop adjustments
You can also use your camera´s raw development software, since Lightroom does not alter the RAW en any way (all the changes are stores in the catalog) then can can open the folder where your RAWs are using the software provided by the camera and just export without editing at all. (I know this works at least for Canon DPP and Olympus' sw.)

comment How do I get accurate color when taking a photo of an LED?
Add more light falling on the faceplate of the device being photographed (use a lamp or a flash), so the camera adjusts to a faster exposure. Part of the problem is that the led is too bright compared to the faceplate. Lis light can be gelled to use a white balance that renders a better color in the led.

comment What are the best and worst diffuser materials for DIY softbox/light tent?
To test my diffusers I shot right at them with the lowest ISO and a very closed aperture (Camera at one side, the source at the other). This lets me test for spread pattern. Also, I set white balance to daylight or flash, so I can detect balance shift. (similar test can be used for reflective diffuser)

comment Is there any protection ring available for reversed lenses?
Judging from the answers, comments and even the duplicate questions, If you ever consider the DYI route, you need to sacrifice a body cap, a lens rear cap and two step rings or two filters and you get a complete lens reversal kit. Glue a body cap to a step ring to thread the lens, and glue a ring to a rear lens cap to allow threading a filter or a regular lens cap on the rear of the reversed lens.

comment How and why do you use an image histogram?
It is also very useful in the opposite condition: if you have been shooting for a long time i low light, then your eyes are accustomed to low light and get into hiper-sensitive mode. The pictures in the LCD will appear too bright to the sensitive eye, but the histogram will tell you closer to actual truth whether your exposure is correct. It also saves you if someone fiddled with your LCD's brightness setting.

comment How and why do you use an image histogram?
Similar test performed on camera: Using "neutral" or "faithful" setting take a picture. Changhe the setting to one that heavily increases contrast and take the same picture (same framing, exposure values, lighting. Preferably without moving the camera from a tripod and right after the first take). Now compare both histograms in camera. They will look diferent, even if the camera was in RAW-Only mode.

comment How and why do you use an image histogram?
Simple proof that Histogram shown is derived from the equivalent JPG: In any Editing/Developing software that allows you to view the image and the applied settings before exporting to a JPG file: each time you make and adjustment like exposure, contrast, curves, etc. The histogram changes. Would this make sense if the histogram was read from the RAW data that has not changed?

comment How can I make a picture like this one of a bridge in green landscape seem less plain?
I use a shortcut for your process: close or cover one eye and look at the picture while "defocusing" the sight. It helps when there are a lot of pictures to evaluate. +1 for the adjustment layers too. If you work with lightroom, local (brushed) adjustments are neat as well.

comment How to get long hair to fan?
This may sound funny but is not a joke: Ask a hairdresser. Maybe your model's hair is "heavy", and there may be a way of makin it lighter, thus easier to fly. For example, hair can be heavy because it had an anti-friz cream applied, or hair gel, or any similar thing. So a hairdresser may know to achieve the look you need for the photo but with lighter hair. Straight (as in opposed to curly) hair that has just been dried with a normal hair dryer is easier to fly.

comment Closeup lenses: do size affect their performance? and how?
@user28116: Only after your comment I understood the intention of the second paragraph. Being that I currently own the mentioned lenses, If I got my hand on one set of diopters, they would be used only on the matching lens.

This is actually a great idea! Simple, functional, practical.

comment What is an easy way to remember the full stop scale?
This has been said in answers already, but for me it has been as simple as memorizing "3". I take a base aperture and know that three cliks up or down is a full aperture stop. In My case I use 5.6 since that is the max that my current zooms have at max focal length. Constantly using only full stop apertures has led me to remembering them whithout specifir effort on memory. Ultimatelly I use f5.6, f.8 and f.11 the most, so they are in my head all the time, if I need to go somewhere else, I go three clicks every time...

The "three click" part is the easy way the OP is really asking for, the rest is too complicated for people who don't like math.

comment Smartphone/Tablet assistant Apps
@Penta: This comment clarifies what you are originally asking. Would you consider rewording your question and possibly include a couple more of examples like your app? Thay would attract better awsers.
