The lens does not actually turn into a different focal length, since that's a real, physical property of the optics that can't be changed without more optics. So from that point of view, the answer is ...
It means the lens focal length doesn't change, but you can change the framing by moving your feet — which in this idiom are wearing sneakers (which, for non-native English speakers, are casual ...
The rule of thirds is a popular and common compositional guideline for photography and for painting. In its most basic form, the rule of thirds suggests that dividing areas within the frame into ...
Theoretically one can do anything. It just takes more glass — and correspondingly, size, weight, and cost. A 300mm f/1.2 lens would need an apparent aperture of 250mm — which is almost 10 inches in ...
What you are looking for is large depth of field. This is an optical property, not something applied as a special effect, so it's not something you can turn on or off. The raw image captures the light ...
The "diagonal method" appears (as seen on a site dedicated to its advocacy) to have been invented — he says "discovered" — in 2006 by photographer and photography teacher Edwin Westhoff. The "method" ...
The two most common aspect ratios for digital photography are 4:3 and 3:2. You will also see a significant number of 1:1 (square) photos and 16:9 ("widescreen") images. 3:2 is the aspect ...
The general answer to this question is: whichever gets you done with worrying about what camera to buy the fastest. For some people, that means get whatever low-end equipment you can afford to start ...
It's six. Remember, the stops are already logarithmic. That is, a 3-stop reduction (as from a 3-stop ND filter) is a 2³× loss of light — ¹⁄₈ of the light gets through. A one stop filter halves light, ...
The answer you found on Yahoo is mostly wrong. The basic statement (same as dpollitt's answer here) is correct — theoretically, image quality shouldn't degrade but a number of factors might make it ...
You're right that the angle of view of the iPhone camera is a little bit wider than a 35mm lens on a full-frame film camera. Up until this point, you're not really confused. But the part after that, ...
I would recommend any of the applications from this list at JPEGclub.org, which develops and maintains software for the Independent JPEG Group. They have a free piece of code called jpegtran which can ...
The dust isn't on the lens — it's on the sensor. Dust on the lens will not resolve so clearly. To check for it quickly, set your aperture to the smallest your lens can support. (Small apertures have ...
Summary A zone plate is a way of focusing light, like a lens, but using Fresnel diffraction instead of refraction. This is cool from a theoretical point of view, because it demonstrates the wave ...
"Distracting" is a word often thrown around in online photo-critique, usually without much specificity. It's a criticism that can be applied to any aspect of a photo without, ultimately, ...
Check out this image by Jeff Schewe from wikipedia. It's a 2D slice of what's really a three-dimensional space, but it makes the basic concept clear: So: sRGB is a subset of AdobeRGB, which is a ...
Sure. If you're in a situation where documenting the events in front of you is more important than making a photograph which looks nice, there's sometimes just no other way. You can open the aperture,...
Polaroid applied for a design mark apparently covering the shape of their prints, but that application was abandoned in 2000. That shape is distinctive, but, for example, Fujifilm Instax looks similar ...
There's so many nice Pentax primes — why pick just one when you can collect a whole set? That's why we have Lens Buying Addiction, after all! In seriousness, based on what you've said, I think the ...
Pardon me while I get a little metaphysical for a bit. "Color" as we understand it isn't a real property of anything in the universe. It's something created by our vision system — a complicated ...
Likely culprits, in order of probability: Bad SD card (by far the most likely, especially with cheap cards). Bad cable or card reader (more common than you might think). Something wrong on your ...
No. If you shoot in RAW, there is nothing lost. In fact, in RAW, the white balance you set in-camera is nothing but advisory information to the post-processing software. A different multiplier is ...
You've got the sun almost in the frame. This is causing huge amounts of veiling flare — light bouncing all around, reducing contrast. You'll get better results from a different angle, or at a ...
The definitive answer for the word in English is Mike Johnston's article on the topic at Luminous Landscape. Mike says "it is properly pronounced with bo as in bone and ke as in Kenneth, with equal ...
Yes, this can work. I know because I've taken photos of children lit only by their birthday-cake candles and they've come out nicely. First, some general tips, without regard to your specific camera. ...
This data was iffy then — not really enough data points, and the trendline is dubious: Source: a very timely xkcd That said, the company DxOMark does measurements of camera sensors all the time, ...
Leaving the batteries in your camera for a week or two between uses will be no problem. If you plan to leave your camera unused for six months to a year, you might want to take them out. And, the ...
Now is the time to take photographs. There are definitely some books you can read that go beyond the technical basics. I highly recommended Michael Freeman's series The Photographer's Eye, The ...
A polarizer cuts out light — about one and a half to two stops, give or take. Additionally, one does not always want the effect. In wide angle shots, it can make skies look distinctively uneven. So, ...
It sounds like you're doing almost everything right, but there's one detail that caught my attention: Aperture highest the lens offers. I'm assuming that this means that you are stopping the lens all ...
