By no means is this an exhaustive glossary, but it is a good starting point. In alphabetical order, then, here are ten basic concepts you should be familiar with: Other than these two virtually- indistinguishable aspect ratios, the most common widescreen aspect is the CinemaScope ratio of 2. Anamorphic lenses are not spherical in the sense that they squeeze an image to fill the negative or sensor, with an additional step necessary during projection to re-stretch the image to the intended size. The odd-looking image here of a lens with an oval aperture demonstrates the non-spherical nature of an anamorphic lens the aperture is perfectly round, but the lens is distorting our view of it.

While it is possible to attach an anamorphic lens to a DSLR, most of us will simply shoot at the native widescreen aspect ratio of Bokeh is a term derived from nofilmschool. Bokeh is a function of shallow depth-of-field see below. As you can imagine, tossing portions of an image has negative side effects, and while many codecs nofilmschool.

On the almost positive side, however, lossy codecs are also the reason we can record hours of footage singlehandedly to inexpensive flash memory devices like CF and SD cards. Bit rate is the amount of data per time that a given codec adheres to; higher bit rates are almost always better because they use less compression. At press time there are no DSLRs that shoot uncompressed video. Depth of Field The amount to which objects in the foreground, mid-ground and background are all in focus at once is a function of depth of field.

A shallow depth of field would mean that only one plane was in focus; a wide or deep depth of field would mean that all planes are in focus at once. Depth of field is determined by the focal distance and nofilmschool. DSLRs exploded in popularity almost singlehandedly because of their ability to render images with a shallow depth of field.

On a basic level, shallow depth of field DOF allows filmmakers to blur out areas of the image they deem to be unimportant or undesired.

No, an electronic shutter. Aperture refers to the adjustable opening near the rear of nofilmschool. A narrow 6. Focal Length aperture creates an image with a wide depth of Technically, focal length refers to the distance over which collimated rays are brought field, whereas a into focus. An easier way to think of it: A large aperture longer focal length, e.

Focal length image with a also refers to angle of view; longer focal lengths have a narrower angle of view, whereas shallower depth of field. When it comes to focal length, a picture is worth a thousand words, so here are images taken with the camera in the same place, but with lenses of different focal lengths attached: Frame Rate narrative material. Frame rate is the frequency with which your DSLR captures consecutive images.

Just kidding. Different frame rates have very different motion rendering characteristics, which, combined with different shutter speeds, produce images that behave very differently.

The relationships between sensitivity and noise is basically linear, however, so the nofilmschool.

Progressive vs. Interlaced Interlacing was a workaround invented for older- tech CRT monitors in the s that has lived far too long. In the early days, video bandwidth was more limited than today, and so engineers found a way to divide a frame into two images and display it using alternating fields. As you can see in this image of a Interlacing can tire wheel, interlacing can cause motion artifacts as cause motion artifacts as well well as a host of other problems.

Progressive scanning is a method that captures and displays the lines of an image in sequence, which is akin to motion picture film with regards to motion rendering. Compared to interlaced images, progressive images have a higher vertical resolution, lower incidence of artifacts, and scale better both spatially and temporally. Luckily, while there are plenty of video cameras that shoot interlaced footage, every DSLR I can think of shoots progressive footage.

Shutter Speed Shutter speed refers to the length of time an image is exposed. Shutter speed affects the amount of light that reaches the camera and also affects the motion rendering of the moving Shutter speed affects the amount of light that reaches the camera and also affects the motion rendering of the moving image. Lower shutter speeds yield a brighter and smoother image up to and including water and light blurring tricks , whereas higher shutter speeds result in a darker and more stroboscopic image.

That was much longer chapter than I anticipated, despite blitzing through these concepts as quickly as possible.

At this point in time I believe the Canon DSLRs offer the best quality and flexibility for filmmakers, due in part to their superior h. However there are several top DSLRs contending for your hard-earned dollars not all Canons ; each camera has its nofilmschool. The main thing to understand while reading the following comparison is how DSLR sensor size affects the images the camera produces. Here is a chart of DSLR sensor size: Also has manual 48KHz audio.

Good build quality. Shoots terrific stills. One important Weaknesses: Canon T2i a. Cinema-sized APS-C sensor size with lots of recording options: Terrific LCD screen. Did I mention the T2i is a great deal? Not much weather coating, and not as good at shooting stills as some of the others slower continuous shooting speed, no top LCD. HDMI-out drops to p during recording. Overheats easily. No manual audio control and no manual white balancing. Canon 7D Strengths: Offers some advantages over its cheaper cousin T2i, chiefly that its HDMI-out stays at i during recording.

Same sensor size and flexible video recording options as the T2i. No manual audio control. Canon engineers applied some magic to the sensor and got some extra low-light performance out of the sensor most famously demonstrated by Nocturne. Beefier batteries, beefier build quality. No manual audio. More than twice as expensive as the 5D Mark II, yet has a smaller sensor. Nikon D3s Strengths: Full frame sensor just like the 5DmkII; the best low-light performer of them nofilmschool.

Probably the best camera in this roundup for taking still photos. Maxes out at p! Crappy recording codec.

Panasonic GH1 Strengths: Not great in low light no matter what you do to the firmware. No manual audio options. To summarize, I still like the Canon 5D Mark II as an all-around great DSLR for both movies and stills despite its quirks; once Canon added 24p and manual 48KHz audio via firmware update, the 5D became a much more viable tool for shooting, say, feature films. Take into account the third or less strengths and weaknesses mentioned above and also check out the forums for further of your overall expenses.

Also, when budgeting for a camera package, assume the camera itself is going to make up a third or less of your overall expenses. This guide focuses on finding quality equipment on a reasonable budget. Canon, Nikon, Panasonic. Feel free to shop around, but digital cameras in particular coverage in the US. These want, however, you can often links should only display USA-based authorized dealers see below for a way to double- find the best check. Also make sure to note the shipping fee — some are non-existent and some are exorbitant.

Good used equipment is Finally, by buying used accessories on eBay, you can save hundreds; the end result is always better than cheap new either significant money saved or more equipment purchased. A final tip: With the extremely high pixel-count CMOS sensors and massive sensor sizes of You will almost current DSLRs, you will almost certainly get a camera that ships with a few hot pixels; video certainly get camera users accustomed to CCD-based imagers may not be ready for this.

However, you should absolutely enter a low-light setting, crank up the ISO, and pan across a plain wall in movie mode to see if you have any persistent dots. The hot pixel issue alone is a good reason to buy to buy from an authorized from an authorized dealer with a decent return policy, as every DSLR is like a box of dealer with a chocolates. Except these days a box of chocolates is not, in fact, like a box of chocolates: How to remove stuck pixels from video footage.

Another issue to be aware of before diving headfirst into the DSLR world is the problem of aliasing moire is an offshoot of the same problem. Aliasing is a problem with DSLRs because the cameras were designed primarily to shoot still photos at much higher resolution than their video mode allows. So, in order to drop from x in still mode to x in video mode, the camera skips lines. For an example, watch the gray rooftop here: This video can be watched on the online version of this chapter, at: Rolling shutter, known informally as jellocam, is another drawback inherent to large CMOS sensors.

Low- light sensitivity! Bayer filtering! Because large CMOS sensors scan top-to-bottom instead of all at once like CCDs, fast movements and pans can cause the image to appear to wobble. I can show you better than I can tell you: This instruction alone, more than any technical nugget contained Witch-style. Also be aware of strobe lights, flash photography, or lightning — such rapid changes of illumination can cause partial exposures, where half of the frame is bright and half of it is dark.

Overheating is an unfortunate side effect money. Here is a timelapse video of a 7D in Live View; when the red flashing temperature icon appears, the camera will shut down.

One of the beauties of DSLR moviemaking is being able to change lenses. After all, many There is no such people buy their first DSLR and only use the all-purpose lens that came with it sort of thing as an defeating the purpose of having a SLR in the first place.

But the stock lens is not suited for narrative filmmaking. Wait, let me stress this a bit more: Yes, for narrative filmmaking, primes are your BFF. They also make you reposition the camera and put filmmaking, some thought into getting a shot rather than automatically reaching for the zoom, the primes are your BFF.

Primes are less expensive than more mechanically complex zoom lenses, and because nofilmschool. When it comes to assembling a kit of lenses, most filmmakers like to choose a brand and stick with it, so the visual characteristics of the lenses match up from shot-to-shot; with the same brand lenses in your kit, the lenses will also handle similarly some have dampened focus rings and true aperture rings, whereas others rely on the camera for aperture selection electronically and have looser focus rings designed for autofocus.

They are incredibly sharp… Be sure to use more fill light when using these lenses and also control your highlights. A very saturated, contrasty lens like the Zeiss would often be an advantage, and I do appreciate their aesthetic I own a Zeiss set myself , but you have to be even more careful with Zeiss lenses to protect your highlights from blowing out harshly.

No, because in video mode, DSLRs use an electronic shutter — the sensor basically turns on and off to regulate exposure, instead of relying on a physical barrier i. Technically, focal length refers to the distance over which collimated rays are brought into focus. An easier way to think of it: A longer focal length, e. Focal length also refers to angle of view; longer focal lengths have a narrower angle of view, whereas shorter focal lengths have a broader angle of view. When it comes to focal length, a picture is worth a thousand words, so here are images taken with the camera in the same place, but with lenses of different focal lengths attached:.

Frame rate is the frequency with which your DSLR captures consecutive images. Just kidding. Different frame rates have very different motion rendering characteristics, which, combined with different shutter speeds, produce images that behave very differently.

ISO is actually the International Organization for Standardization, which is why you see it used in lots of places beyond photography — many businesses are certified ISO: The relationships between sensitivity and noise is basically linear, however, so the higher the ISO, the brighter the image — and the more noise contained in the image.
