1. your camera (manufacturer & model)

answer:

- Nikon D800

2. the sensor size (in mm: ? x ?), maximum megapixel rating, sensor type (eg “APS-H”)

answer: 35.9 × 24 mm Full Frame, 36 megapixels
-

3. lenses you own & can use on your video recording-capable camera 

    — in 35mm equivalent focal length range, associated widest apertures

answer: 28-70mm f2.8, 80-200mm f2.8, 60mm f2.8

-  

4. biggest memory card you own in terms of capacity (in GB), class (eg “class 10”), 

   and card speed (eg. x 133). 

   If it’s an SD type card, which class is it?  (e.g.. class 10)

   Read the following article from B&H PhotoVideo which indicates all relevant aspects of cards:
   Memory Cards Explained

   Which class of card do you need for shooting video? What does your SD card classification 

   mean in terms of writing speed: is it fast enough to be shooting video?

answers: I have a 32gb compact flash card, udma 7, 160mb/s

-  

5. How many minutes of video capacity does your biggest memory card have shooting at both the

     highest & lowest resolution capture settings?

     Also, does your camera have a limit on the amount of video shooting time?

     What is the technical reason for limiting single shot video shooting time?

     State your answers as memory card size / recording quality (resolution & mode) & maximum minutes

     ( eg. 8GB memory card / 1280 x 720p [SD mode] yields 20 min. of video)

     (NB. you will probably have to test this out by turning on your camera with your empty reformatted

     memory card installed, the display set to indicate total frames remaining/total video time available,

     video quality set to highest and then lowest resolutions)

answers:

- highest resolution no. of minutes: 32GB memory card / 1,920 x 1,080p [compact flash mode] yields 22 min. of video

- lowest resolution no. of minutes: 32GB memory card / 1,280 x 720p [compact flash mode] yields 44min

6. maximum file size per clip        

answer:

- 4gb

8. format of movie files created (eg. QuickTime Motion JPEG, AVCHD, MPEG4, etc.)

    (... there’ll probably be more than one, depending on camera and resolution sizes & modes) 

answers:
-.mov
-

9. which video output resolutions does your camera produce? 

     try to include all of the following info for each level of video resolution your camera produces:

- (sample answer might be:     720p / 1280 x 720 pixels/ SD / 4:3 / 30fps)

               answers:

-  720p / 1280 x 720 pixels/ compact flash / 16:9 / 60fps 50fps 30fps 25fps

-  1080p/ 1,920 x 1,080pixels/ compact flash / 16:9/ 30fps 25fps 24fps

10. looking at the above resolution dimensions available, are they using the same aspect ratio or not? 
      (eg. 800 x 600 is a 4:3 aspect ratio while 1920 x 1080 is a 16:9 aspect ratio). 
      What are the differing aspect ratios for each of your camera's video format resolutions?

answers:
- 16:9
-

11. shutter speed range your camera can record video in: does your camera permit you to set shutter

      speed when recording video? (Can you in fact set manual setting for video shooting?) Whether it

      does or not, what shutter speeds can you set on your camera for shooting video?

answers:

- 25 to 8000

12. aperture: does your camera permit you to set the aperture when recording video?

             answers:

-yes

    

13. shutter speed & aperture restrictions — answer this only if your camera does not permit you to 

       choose manual video shooting settings.

       If your camera doesn’t have manual setting capabilities, what other camera setting can you use to

       control exposure then?

  answers:

-

14. focus: how does your camera focus when shooting video? Does it permit you to manually focus

       or are you left with autofocus only?

eg. — The most important thing to know about the Nikon D5000’s video controls is the fact that the camera cannot 

autofocus while video is being recorded. You can autofocus the image before recording begins (by pressing the shutter 
button halfway down, just like you do with still images), but once you start recording you must manually focus 
everything..When you try to autofocus while recording, the camera lens moves and changes exposure just as if 
you’re autofocusing a still image.
answers: 
-  Yes the D800 permits me to manually focus before and while shooting the video.

15. your camera records video at what data rate (expressed in MB/sec. or mbps)

answer:
- 1920 -12mb/s ,24mb/s

16. specific and particular settings recommended for your camera model — the best way to 

      do this is to look at the camera reviews for your model on preview.com and/or imaging resource.com

      and read their review section on the video functioning (often listed as “video” or “movie” review section). 
      You can also research this in a Google search —eg. at least one very popular camera (hint: 5D) has

      suggested settings for ISO to obtain the least noise in video mode.

answers: The D800 is an overall good camera for video and pictures. With it's 36 megapixels the resolution is 

impecable.

HDR - Higher Dynamic Range

N developed

16bit HDR +/-3 stops

32bit HDR +/-6 stops

Histogram

a.   In the high key image the histogram falls more on the right side. 

b.    Not in this image because their aren't any highlight clipping.

c.     In the low key image the histogram falls more on the left side. 

d.      Not in this image because their aren't any shadow clipping.

e.   The pixels are pretty much everywhere but they are a bit more to the left side.

f.      Yes their is in the highlights.

g.     Yes because it was not clipping any of the highlights or shadows in the high key and low key pictures. 

h.    the mixed one because it has information everywhere in the histogram

Aperture and Shutter Speed Assignment

Lens Depth Distortions

Telephoto

70mm 
  
- camera approx. 1 meter from stool

- Stool is not stretched

- Background is not distorted

-The with of the photo is a lot narrower then the WA lens.

-As for distance, with the telephoto the background is a lot closer to the object.

-For the telephoto, the object contracts and does not really enlarge.

Wide Angle

28mm

- camera approx. .4 meter from horse

- stool is obviously distorted & stretched

- Background is obviously distorted

-The with of this photo is a lot wider and we see a lot more of the background.

-For the background distance, it is a lot further with the wide angle

-For the wide angle, the object expands and enlarges a lot in the bottom

Telephoto

70mm

- camera approx. 1 meter from subject

- subject is not stretched

- Background is not distorted

-The with of the photo is a lot narrower then the WA lens.

-As for distance, with the telephoto the background is a lot closer to the subject then with the wide shot.

-For the telephoto, the subject  looks a lot more normal than the wide angle lens

Wide Angle

28mm

- camera approx. .4 meter from horse

- stool is obviously distorted & stretched

- Background is obviously distorted 

-The with of this photo is a lot wider and we see a lot more of the background.

-For the background distance, it is a lot further with the wide angle.

-For the wide angle, the subject gets distorted compare to the telephoto shots. 

Scenario: imagine that you're shooting a model (full body) against a seamless. Your

framing of the model is what you want but the edges (and beyond) of the seamless are

visible in your frame. You don't want to move the model back towards the seamless and  

you don't want to have to retouch out the seamless edges. Applying what you learned 
from this exercise today, what's the solution using just your camera & lens?

So for this scenario I would get a telephoto lens to shoot the subject so that the background would fill the frame and we would not se the edges of the backdrop

For the noise reduction setting my camera didn't do much of a big difference with the low iso's but around 3200 iso we started noticing one. In my opinion the highest noise reduction setting is the best because it removes the most noise without loosing much sharpness.

In this image the white balance is pretty neutral .

For this image the white balance is a lot warmer and orange like. It doesn't seem as natural in my opinion.

This one is the opposite as the one above it is a lot colder(blue) but could potentially look more normal then the orange one because it is winter and their is that feeling.

This image was purposely shot in the wrong white balance to give the image and overall feeling. I shot this image with a bluer setting to give the image a colder and more sinister fell to it. This image would be better for a scary purpose but not as good for a happy and warming one.
