lab 7
1. your camera (manufacturer & model)
its an cannon eos rebel T6i
-
2. the sensor size (in mm: ? x ?), maximum megapixel rating, sensor type (eg “APS-H”)
sensor size: 22.3mm x 14.9mm (APS-C)
maximun megapixel rating: Total pixels: Approx. 24.70 megapixels
-
3. lenses you own & can use on your video recording-capable camera
— in 35mm equivalent focal length range, associated widest apertures
- 50 mm > 75 mm
-18-55 > 28.8 - 88 mm full frame
-28-105 . > 44.8 - 168 mm full frame
-55-250 . > 88 - 400 mm full frame
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?
the memory card i have is a samsung evolve micro usb its 64 gb
class 10 and speed is 3
so i think you want a card in the sdxc class to make i fast enough and good enough to film. mine i think is okay but not the best on the market.
-
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: i have a 64 gb
- 1920 by 1080: 2 hours and 20 min
- 640 x 480: 11 hours and 40 minutes
- i can film for a total of 30 minutes before it shots off they limit this so the eternal part of the camera doesnt get to hot it stops to give it an opportunity to cool down.
6. maximum file size per clip
for an FHD i can go 216 mb per minute
-
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: i have FDH files
-
-
-
-
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:
- so i have a 1920 x 1080 its a FHD file and the aspect ratio is 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:
- FHD and HD use the same aspect ratio of 16:9
- FHD and HD use the same aspect ratio of 16:9
- and for SD the aspect ratio is 4:3
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:
-yes it does i can go from 30 to 4000
12. aperture: does your camera permit you to set the aperture when recording video?
answers:
-yes it does i can do anything all the stops my lens allows
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:
-
so for the canon rebel t6i you have the ability to use manual focus while you are filming and you can use manual focus, but when you use autofocus the camera goes in and out and changes the focus half way through the video

everything..When you try to autofocus while recording, the camera lens moves and changes exposure just as if

15. your camera records video at what data rate (expressed in MB/sec. or mbps)
answer:
-3.6 mbps
-3.6 mbps
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
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:
- so there was a big issue with the rebel t6i sensor when they first came were they had to bring them all in to be fixed apparently it was full of little white dots and they didn't know how to fix it so they had to bring all of the models in but they figured out and fixed it for free.

lab 5
i do feel that it is exposing properly and giving me good range just because they are all not clipping and are generally in the right zones to be abled to print them with out a hassel. to me my low key one shows the most dynamic range just because its has the most spread out tones like there may not be much but it reaches all the way out into the highlight , like its really spread even though it is mostly a low key image.
the pixels are more to the left side to the image like it goes a little further or closer to the edge you can say and they are much higher so it most definitely has more dark tones i think. umm no not really actually nothing is clipping its pretty well centered so i think its al gonna print well.
in this histogram they are mostly to the left, i don't think any of it would clip because i'm not super close to the edges but i am getting a little close to the edge
in this histogram most of the pixels fall on the right side of it. i think it would all fit with detail because its not super on the edge of the histogram there is still some empty space before clipping.

lab 4 length depth distorsions
iso 800 f/ 4.5 1/160 sec focal length: 80
- everything looks like its compressed like they are flat and no longer having a foreground/background relationship.
- background looks closer to subject
- books look tinier and less like the focal point
wide |
iso/800 f/ 3.5 1/200 sec .focal length 28 mm
- books look really big
- different layers of information
- everything has its on like level nothing looks compressed
telephoto |
iso/ 100 f/ 4.5 1 sec focal point: 80
- lockers are less focused and look more flat
- people feel more their size and farther away
- the lockers look extremely disorted
