The shutter you hear is a mechanical shutter and it cannot on a DSLR move fast enough to shoot at video speeds which is between 24 and 60 FPS. High-end mechanical shutters usually top at 12 FPS. The shutter used in video and high-speed drive on some cameras is an electronic shutter. There are no moving parts involved and hence no sound. The sensor simply ...

You can definitely take better pictures of small children with a single shot and you don't even have to be an experienced photographer (but you do need a good camera, see last paragraph). I'm not an experienced photographer, I mostly take pictures of my two (very fast) children and I used to think continuous drive is a great advantage in photographing ...

Several things can limit the maximum potential frame rate. While sensor read on a mirrorless camera can be very fast, theoretically allowing frame rates above 12, the whole read and image processing pipeline has to support the desired frame rate. In addition to the sensor, you also have the ADC (which may be on or off die, and parallel or not), the image ...

Why do high resolution cameras shoot stills at high resolutions, but only typically shoot video at 1080p which is about 2 megapixels? For example I have a Sony-NEX 6 which can shoot stills at 16 megapixels but only 1080p by 1920p video. There are several reasons why most high resolution still cameras that also shoot video don't produce video at ...

Different meanings of FPS. Yes, FPS is a measure of frame speed for video, but it is also a measure of the burst speed of a camera. Video frame rates are typically 24, 25, 29.97, 30, 60, 120, 240 or 480. The FPS that is generally referenced when talking about still cameras is not the same. It is the number of full pictures that the camera can take per ...

Rule #1 is to get out of their way and just wait for their expressions. It is more or less like nature photography, where you wait for hours to get the right shot (easier for you because babies are slower than birds :) ). You should be able to anticipate the emotions and have your subject in focus before the onset of the emotion. I have shot a couple of ...

If you have a viewfinder, I would bring the camera up to your eye, and pre-focus if possible, then just wait it out for that perfect moment. If the subject moves considerably, you have to keep pre-focusing by pressing down the shutter button halfway until you are ready to fully depress it and capture an image. If you do not have a viewfinder, the LCD screen ...

Practice, practice, practice. I think spontaneous people photography is one of the harder areas to master. Unlike landscape, still life, studio work etc it's something you have little control over. The only way to get it right in my opinion is to keep at it, and practice lots. That way you get used to how your subjects react, when best to click the shutter ...

Data rates, data rates, data rates. A high resolution photo from a 24 megapixel sensor for example is 20 to 30MB in raw or 10MB in high quality jpeg. If you were to store that many frames for video, that would be 240MB to 720MB per second. No SD card can write that fast and the amount of information that would have to be processed by the image processing ...

Would I have to resort to some special programs to extract the images from the video file? Yes, you can grab frames from the movie file, but they'll have much lower resolution than a full-sized photo. A 1080p frame is a 2.1 megapixel image, whereas the camera is capable of taking 18 megapixel photos. If the lower resolution doesn't bother you, there's ...

What you are comparing are the limits manufacturers chose to implement on thos models. It is not a reflection of what is possible but of what they choose to build in order to make it into a viable product. Speed is limited by the slowest component in a chain. So, in order to make faster continuous shooting possible, the camera must have correspondingly fast ...

Magic Lantern has a RAW video mode - but it is only for Canon DSLR's.

The buffer is a fast RAM of limited size. While it fills up with photos during a burst (or only after it's full in some implementations), the data is written to the storage card, which is much slower. So the full published burst speed is only available while there's still space left in the buffer, once it is full, your burst speed will typically be ...

Then is it when the buffer is filled with 12 photos, the camera can't shoot anymore photos? Am I correct? Not quite. Many cameras may write some photos already before the moment of filling the buffer and burst will be longer. The speed of writing photos from buffer to the card indeed depends on the processing throughput. If camera writes photos to the ...

Answering this question from the comments, I'm essentially interested in 30 fps images. Is any device, DSLR or otherwise, capable of taking high-res images at 30fps? Yes, there are devices that can record high resolution video or video stills. Red makes a range of high resolution / high-fps (or both) video cameras. Their current (as of Feb 2016) ...

In some regions, Canon has included RemoteCapture DC software with the G10. On Windows, there's PSRemote. I have no direct experience with gphoto2, but its idea seems to be quite simple, translating requested commands to camera-specific datagrams and as such the library itself is unlikely to be a major cause for slowness. Rather, the G10 firmware seems to ...

The basic answer here is: usually, no one cares. For the art of photography, cameras are meant to record images for the purpose of viewing, not metadata for the purpose of scientific instrumentation. The prevailing EXIF standard for metadata doesn't even record timestamps more precisely than one second, and there's usually no provision for network time ...

The answer is electronic shutters on CMOS simply cannot do shutter speeds faster than their readout time, which in your example sensor is 10ms (1/100s). The readout time is fixed, and it's not possible to start readout of the next frame before the readout of the last frame has finished or to somehow speed up readout. The only exception is if the CMOS ...

Both. It is of no importance for the genre of still photography, but it is or may be when you use "still" just to distinguish between photography and filming. The fps rate is of vast importance for some (or most?) sport photographers.

Let's say the average DSLR shoots at around 10MP (and that's probably a low estimate these days.) The number of pixels in a 10MP photo is around 3872 x 2592 (assuming a somewhat standard sensor.) Clearly much larger than your 1080 x 1920 video. "10MP video" would be in the 4k range. Which by the way is all the rage these days. :) There's also the fact that ...

A still frame from a modern camera is 15+ megapixels, and potentially going to have every pixel looked at with a critical eye. A frame of HD video is 2 megapixels, and not going to subjected to the same level of analysis at 100% crop; at this point, I think it's more a question of why you'd think they would have the same frame rate.

It is not so much the burst rate but the shutter speed that makes your photo blurred or not. For normal walk ~1/125s will "freeze" the motion, while for "rambunctious" (I'll have to check the exact translation of that but :-D anyway) kids I would recommend at least 1/500s. This can indeed be made possible by increasing the ISO (sensitivity), but that also ...


1

The burst rate should be based on the amount of action and how closely you need to be able to catch the shot. You should be able to adjust shutter speed to get less blur even if only doing 2 frames per second (or even just a single photo). I would recommend using a shutter fast enough to stop the motion with enough light to prevent needing high ISO and ...

The dpreview page for Nikon D4 mentions that the camera can shoot 9-11 fps. Considering 11 fps is the absolute maximum, but it can go as low as 9 fps, we can conclude that the Nikon D4 can in fact shoot at about 9 fps when capturing 14 bits/pixel. This is because the processor takes longer to write the increased amount of information to the memory (14 bits ...

It also helps to raise your ISO so you can accomodate that high shutter speed. High shutter speed = less time/less overall light but high ISO = greater sensitivity so it balances out. Pre focusing as others have said before also helps but perhaps changing to manual focus mode might be an even better option depending on the plane of focus - i.e. if the kids ...

In sports, the play starts and ends in instants. A high frame rate increases your chances of getting at least some record of that. With children, it's a matter of coaxing and getting the right expression. They aren't really going to escape as a fleeting sporting play might. They will remain there so long as the parent works with them. Imagine this: You have ...
