พื้้นฐานการถ่ายวีดีโอด้วยกล้อง DSLR กับ Philip Bloom

หลังที่จากเคยรวบรวมวีดีโอพื้นมาแล้วก่อนหน้านี้ มาดูขาประจำเกี่ยวกับกล้อง DSLR บ้างผมจะแบ่งเป็นเรื่องๆ ไปเหมือนเดิม (มีคนบอกว่าดูอย่างงี้ง่าย กว่าโหลด อิอิ)
Introduction to DSLR Cameras

Step 1: Research

Advantages of shooting video with a DSLR camera.
    High Quality -- Nearly every DSLR camera that shoots video can shoot in 1080p, which is very high quality HD.Film Look -- DSLR cameras can imitate the look of film very well. This means your videos will look like what you see when you go to the movies!Also a Stills Camera -- Remember, your DSLR is primarily a stills camera, which means you can easy go back and forth between video and photo mode.



Step 2: Getting the camera ready to shoot
Go into your MenuSelect Picture StyleSelect User Def 1Change your picture style to NeutralTurn Contrast all the way downTurn the Saturation down two notches


Step 3: Choosing a lens
Before we start, here are some things you need to know for this lesson:
Aperture is the size of the opening within your lens that allows light onto the image sensor. Aperture is measured by f-number or f-stops.
F-stop is a term used to describe the size of the aperture opening in your lens. The lower the F-stop number, the bigger the aperture. If the aperture is low, more light is able reach the image sensor. F-stop settings are normally displayed with a forward slash.
Common f-stops are: f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, and f/22.





Step 4: Gearing up

Step 5: Camera Settings and Shooting Techniques
Shutter Speed
Shutter speed is how long the sensor in your camera is exposed to light. To maintain the film look of shooting videos with your DSLR, you want to make sure your shutter speed in synchronous to your framerate. If you are shooting in 24p or 25p you will want to set your shutter speed to 50 (1/50th of a second). Shooting in 30p, set your shutter speed to 60 or 1/60th. 50p or 60p, shoot at 100 and 120 respectively. These setting will give you the best looking video.



Step 6 Ways to Record Sound with External Devices
External microphones
Your DSLR camera records sound, but the quality isn't that great. What's a quick way to record better sound? One word: external microphones. Okay, that's two words. External microphones usually attach to the top of your camera and plug into the camera's microphone jack on the side. There are different types of external microphones, but the two most common are shotgun and stereo microphones. Depending on what you are shooting you will want to use different microphones. Shooting with shotgun and stereo microphones isn't perfect, but it is much better than just using the mic built into your camera's body. 



Step 7 Bend the Space-Time Continuum with a Timelapse
Timelapses are one of the most popular things to do with DSLRs because the camera is first and foremost a stills camera. This means the resolution of your still images is much higher, which allows you to get some really beautiful timelapses. 



Step 8: Getting a Good Shot in Low Light Conditions
Use lenses with low f-stops -- The lower the f-stop, the wider your aperture will be meaning the more light will hit your sensor. Need a recap on what these terms mean? Check our handyGlossary.Choose a white balance that will stay true to the look the light is giving you -- dusk can give you some nice bluish tints that really indicate that it's dusk. If your white balance is off a little, it will give your image a different color tint and may look a little weird. Of course, you may like that weird look, so it's up to you.Bump up your ISO -- if you have a full frame camera, you can push it up to around 3200 ISO without your image being super super grainy. With a cropped sensor, you can push it up to about 1600 ISO. If you bump your ISO to these respective settings and you still can't get a good image, you call always go higher, but your image will become more grainy. I recommend experimenting a little and go out at night and shoot video with different high ISOs to see the difference.
