"The Exposure Triangle" is a catchy phrase meant to encompass the three factors which affect the exposure of a photograph of a scene with a given amount of light. It's often given to new photographers ...
There is a tool called dcraw which reads various RAW file types and extracts pixel data from them — it's actually the original code at the very bottom of a lot of open source and even commercial RAW ...
Originally, film formats were arbitrary and specific to each camera model. For example, Kodak started making "pocket" cameras in 1895, but each new design used a different format. By 1908, they ...
In layman's terms (assuming a layman who knows some very basic geometry), imagine your nose as the point of a triangle. The left side of the triangle is the left edge of your peripheral vision, and ...
There are many characteristics which make better lenses better. The basic goal of a lens is to render an ideal replica of the framed scene, but because of the limitations of the real world, that's ...
The "times zoom" notation is simply the big number divided by the small one, so the examples you give are correct. "3x zoom" simply means the longest focal length is three times the shortest. This ...
A picture is worth a thousand words, here. This is a Twin Lens Reflex camera: The two lenses are linked together so they focus as a set (either the whole front panel moves, or the lenses are linked ...
Gimp is great, but it's not without some shortcomings. Photoshop is a big-time commercial project with a lot of funding, and while Gimp's development community is awesome, there are a lot of areas ...

Legit contests which have entry fees have those fees because they get too many entries. Sure, they may offset some expenses, but basically the payment exists to make people think twice about entering. ...
Yes. There is development in four areas: computer design, material science, features, and finally a category I'm going to call "not better just different". Computer Design Lens design has always ...
Legally, and in typical business practices, what the photographer told you is completely true — she has no obligation to give you RAW files, unless the contract says otherwise. Presumably, the ...
Why are hardware-based manipulations, like black and white photography (traditionally using black-and-white film), long exposure, etc., which also result in an "unnatural" image, acceptable while ...
The first photographic images printed in newspapers were actually wood engravings meticulously hand-copied from a photograph printed in the normal way. By the 1890s, however, prints were made in ...
Aperture simply means "opening", and in photography we use the term to refer to the diameter of the opening in a special adjustable diaphragm within each lens. When this diaphragm is constricted, ...
On the contrary, I think these cameras are better for beginners, if your intention is really to begin — that is, to start from here and (as you say) get into photography. The lower-priced entry-level ...
Digital camera sensor format-size names have their roots in television camera tubes. These were measured in inches diagonal, but for various practical reasons, the entire circle isn't used. So, from ...
There are at least four reasons. Resolution First, although the same sensor may be used, video generally uses only a portion of it (either by skipping lines or some more sophisticated method). 4K UHD ...
You can do wedding photography with a smartphone. It's not really the gear — it's the skill. But, this is mostly a matter of expectations. Some people will expect expect you to have much higher-end ...
Yes, there's something you can do. Stop using the card and replace it. Even reputable, high-quality cards have failures. And every such device has a limited lifespan. Don't risk it. You may do ...
Note: The landscape has changed significantly in the past seven years, and this answer really needs an update, which I will do when I get a chance. Notably, Olympus has exited the DSLR market in favor ...
I'm going to crib from my answer to an earlier question on aperture: When the aperture is very small, the admitted light is highly "collimated", which is a fancy way of saying "all the rays are ...
Short answer So, not being quite satisfied, I did some research. Here's the tl;dr answer, but I hope you find the rest as interesting as I did. In painting and in photography, the "key" of an image ...
What you're looking at through the viewfinder is actually the image from the lens projected onto a ground-glass viewing screen. You want the diopter level to be adjusted so you can see that most ...
I think you've answered the question yourself pretty well, with citations and everything. There's little real risk, and the flash manufacturers are erring on the side of caution in order to protect ...
My other answer aside, I think almost all "beginner mistakes" boil down to one of a few things: Not being mindful of what's in the composition. The uneven horizon falls under this, as does the ...
Going from negative film to a printed image is a two-step process. First, the negative is developed — the latent image on the film brought out and then fixed in place. Now you have a piece of ...
"GAS" is a joking acronym for "Gear Acquisition Syndrome" — basically, a hobby that is adjacent to photography. See also "Lens Acquisition Syndrome" and similar. It means buying new equipment for its ...
This is a Sigma name for one of their lens lines. It is not a general purpose term and really only has the marketing meaning Sigma ascribes to it. From the Sigma website, that definition is: ...
