1. your camera (manufacturer & model)
answer:
- Canon 1200D EOS Rebel T5
2. the sensor size (in mm: ? x ?), maximum megapixel rating, sensor type (eg “APS-H”)
answer:
-Senor Size: APS-C (22.3 x 14.9 mm)
-Senor Size: APS-C (22.3 x 14.9 mm)
-Maximum Megapixel : 18 Megapixels
-Sensor Type: CMOS
3. lenses you own & can use on your video recording-capable camera
— in 35mm equivalent focal length range, associated widest apertures
answer:
- 18mm lense
Equivalent is 28.8mm at f 4.5
- 55mm lense
Equivalent is 88mm at f 4.5
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
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:
- Class 10
no other information my card
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 / 1920 x 1080p 30 minutes
- lowest resolution no. of minutes: 32GB memory Card / 640 x 480 25fps 30 minutes
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:
-H.264
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:
- 30fps(options) 1920 x 1080 16:9
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?
(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:
-1920 X 1080 is a 16:9 aspect ratio
-1280 x 720 is a 16:9 aspect ratio
-640 x 480 is a 4:3 aspect ratio11. 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:
-I have manual exposure controls in video. I can shoot from 1/30 to 1/4000
12. aperture: does your camera permit you to set the aperture when recording video?
answers:
-Yes
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:
15. your camera records video at what data rate (expressed in MB/sec. or mbps)
answer:
-216 MB/min
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

Varied Histogram
Questions
a. According to the histogram, where do most of the pixels in your high key image fall (left or right on the histogram)
- Right Side of the histogram
b. Are there any pixels in the high key image that would not print with detail?
- No because there is no clipping in the image.
c. According to the histogram, where do most of the pixels in your low-key image fall (left or right on the histogram)
- Mostly to the left of the histogram.
d. Are there any pixels in the low-key image that would not print with detail?
- Yes there is clipping in the dark tones of the picture, so the black background closest to the edges of the frame that would lose detail in the shot.
e. According to the histogram, where do most of the pixels in your varied tones image fall (left or right on the histogram)
- There is a lot of dynamic range in this shot and as a result is spread over the histogram relatively evenly.
f. Are there any pixels in the varied tones image that would not print with detail?
- No, all the tones captured in the image fall within the histogram without any clipping.
g. Considering the information on the histogram, do you feel your camera is properly exposing the high key and low-key scenes? Explain your answer
- I feel like is struggles when capturing dark tones. My camera could expose for the cup but had trouble getting out all the details in the dark area. I think if it only had to expose for dark tones it would have done better but the fact that the subject and the dark background are so different, my camera struggled when trying to expose them both accurately.
h. Which histogram shows the most dynamic range?
- My shot with the varied toned background had the most dynamic range.
