Actually 1/125 is half of 1/60, ±0.06 f-stop. It should be obvious by looking at shutter speeds that they were chosen to be the reciprocal of nice round numbers. Start with 1 second and keep dividing it by 2. Note that you missed the discrepancy between 1/16 s and 1/15 s. If you kept going in strict mathematical multiples of 2, then 1/60 s should ...

Yes, professionals do use auto mode. Professional paparazzi use auto mode almost exclusively and will sometimes even tape up the controls on the camera to prevent any settings being accidentally altered. You don't have to know how to shoot manual to make money out of photography, if for example you know which restaurants which celebrities go to... Other ...

The difference between the "actual" shutter speeds at powers of 2 (1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128, 1/256, 1/512, 1/1024, etc.) and the rounded numbers we use (1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, etc.) is so trivial as to be beyond the limits of the vast majority of cameras in existence to accurately differentiate. Most ...

This is normal because in the day time, the sky is usually the brightest part of the scene. If you lower the exposure by applying negative exposure compensation, your sky will get darker and more blue. This will cause other elements in the image to darken and some may end under-exposed. This is because a change in exposure is global. What you need is to ...

A digital sensor isn't really best described as "reading data". A much better way to describe it is "collecting photons" that are then converted into data by measuring the microscopic electrical charges they produce once the collection period is over. They do not have the capability to continuously record the changing state of each pixel well as they collect ...

Most DLSRs with "silent" or "quiet" shutter modes don't change the speed at which the shutter is operated at all. The transit time each curtain takes to traverse the height of the sensor is constant regardless of the exposure time (shutter speed) selected or if a "quiet" mode is selected. Exposure time is determined by the time difference between the ...

Camera settings are never going to make this easy. Photographs need light to work, and while modern sensors are actually quite sensitive, they can't live up to our perceptions, because our brains take the dark, noisy image from our eyes and subconsciously make a mental model where the imperfections aren't noticed. You don't mention what lens you are using, ...

Have you heard about the "sunny 16" rule? (In bright sunlight, when you set your aperture to f/16, the shutter speed is 1/ISO). I just checked, I've set my camera to f/16, 1/100, ISO 100 and pointed it to an object in direct sunlight and the meter showed -1/3, I then used an iPhone app to find the corresponding rule for open shadow, pointed the camera at ...

You activated by mistake an advanced view mode. You can switch between view modes by pressing "info" (or maybe "display" for you) when in view mode. The view switchs in that order (sorry for image quality) : Classical View : your photo and some settings and nothing else Classical View with more information : your photo, some settings image quality ...

Your question is based upon an assumption that is not entirely correct: that you can change just about everything in any shot you take. You can't. Things such as depth of field and shutter speed are set at the time the picture is taken. If, for example, the shutter speed is too slow to freeze a moving subject there is absolutely nothing you can do in post ...

This comes down to software patents — not on dates, but in a way that limits filenames. The only filesystem which is widely available and cross-platform is FAT, the venerable Microsoft DOS filesystem. It works on both old and new versions of Windows, worked on OS/2, works on Macs, works on Linux, and there are plenty of embedded implementations for the mini ...

Sadly, the feature's name is misleading. In fact, I'd go so far as to say that it's wrong, if not an outright lie. Turning this option on just enables you to use exposure compensation — it doesn't let you do anything actually "manual". If you enable this option, the ... menu at the lower right of the screen gains a +/- icon, as typically indicates exposure ...

"Auto" can mean a wide range of things. Most DSLRs offer a "full auto" facility that tends to manage shutter speed, aperture, ISO and more. But most of the modes on a DSLR that are other than absolute manual mode offer a substantial automated component. And even "Manual" may have auto features lurking in the shadows (literally in some cases). Your friends ...

The size settings actually set two different things for any JPEG images taken by the camera: the resolution of the image being taken (the # x # size), and the quality setting for the JPEG compression for the image. The L, M, and S sizes vary individually by the camera, but the numbers at the top in the blue bar tell you the pixel dimensions. So, in this ...

Image size is what if often called resolution, basically the number of pixels stored in the image file. So on a 12 megapixel camera, you can usually choose between 12 MP, 6 MP and 3 MP or similar values. Image quality is independent of size and is usually called compression. This controls how much information is discarded from images while they are saved. ...

We already have some of the technology for this. Our term for remembering the sensor readings at each exposure point is "video", and what you are asking for is reconstruction of an optimal still image from multiple video frames. For an overview of Microsoft Research work on this, start here: ...

Aperture: Use the maximum aperture (F1.8 if possible) Shutter Speed: Use the 600/(focal length * crop Factor)rule so as to not see star trails (Refer here in section 3. Camera settings). ISO: Highest possible for your camera that you find acceptable. Milky Way? You can use the application: Stellarium to find out if you are in the right time / place to view ...

Unfortunately, this looks very much like whoever changed your headset port has also managed to damage the camera module in some way so that it is massively overexposing. This is very unlikely to be fixable by an amateur - I'd suggest taking it back to the store that changed the headset port and getting them to either fix it or give you a replacement phone, ...

You apparently have Highlight Correction activated. This forces the higher ISO limit (usually forcing it from 100 to 200, though you also have Expanded Sensitivity enabled, which gives you a broader ISO range starting at 80, thus now 160). So, there's nothing wrong with your camera. Mind you: Options you find that look superior may come with a downside. ...

Without a tripod you will have to have a very steady hand to make real use of the length of your 70-200mm, so I would go with the 24-70mm. The wider end will allow you to take in the majority of buildings and the tele end will let you zoom in on features. There is little point in using Shutter Priority when photographing static subjects. You will be much ...

This behavior is caused by automatic exposure bracketing. I've had someone with a Nikon D5000 behaving the same way in manual mode, and it turns out that automatic exposure bracketing caused this problem. My Pentax K-5 behaves the same way if the drive mode is set to exposure bracketing in manual exposure mode. If this does happen to you again, make sure ...

Three things: Practice. Make the adjustments you need second nature, so you can make them with thought only to why you want to make the change, not how to do it. Don't take your eyes away from the finder to make adjustments, if you can at all help it. Get a camera with good dedicated controls, because #2 is impossible when everything is menu-driven. I ...

Just set a black and white picture style but keep the file type set to raw. See this post for more information: Do different "Picture styles" affect RAW output?

A pop-up flash has barely enough power to work indoors of a residential space; in larger rooms, professional photographers have practical reasons why they carry separate large flashguns. The Puffer, whilst making the light slightly less harsh and therefore more pleasing, does it so at the expense of chewing the power even further down. So, your gear is ...

There is no way to change the cameras ISO when you are on the preset Auto mode. This is typical of all cameras. This is because by being in Auto you are telling the camera that you want it to control all the settings. Hence the greyed out ISO control. You can try changing the camera mode to P (Program) which is still an auto mode; but it gives you slightly ...

The original question is based on incorrect assumption (about digital sensor not changing state during the exposure) but the concept is related to the Quanta Image Sensor (QIS) idea researched by Eric Fossum. http://engineering.dartmouth.edu/research/advanced-image-sensors-and-camera-systems/ The QIS is a revolutionary change in the way we collect ...

In such situations i would usually be in Aperture priority mode instead of Manual I set my ISO setting to Auto to let the camera compensate for any wrong settings for aperture or shutter speed (refer to this question for the advantages and disadvantages of auto ISO). Also i would set the metering mode to spot metering to get what i want in the right ...

It is simply a convention because 30s was deemed a reasonable limit. Nikon, Pentax and Sony all use 30s but Olympus uses 60s. Panasonic uses 60s on most camera but up to 250s. As you can tell by the presence of Bulb mode, most cameras can do more. Olympus limits theirs to 30 minutes to avoid the sensor over-heating or building up too much noise. Other ...
