Lab 7

1. your camera (manufacturer & model)

- My camera is a Canon EOS rebel T6

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

- APS-C (22.3 x 14.9 mm) 

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

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

answer: kit lense 18 x 55 mm >

50 mm telephoto lense > 75 mm full frame

18 x 55 mm kit lense > 28.8 mm x 88 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

   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: 32 GB, Class 10, card speed: 1

The class of card that I need for shooting video is SDXC class.  My SD card is not fast enough to shoot video.  

               

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: 1920 x 1080/1h28 minutes

- lowest resolution no. of minutes: 640 x 480/5h40 minutes

6. maximum file size per clip        

answer: 340 MB/min

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, MPEG-4 (MP4/M4V), MXF, AVI

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:

-  (30p/25p/24p) /1920 x 1080 pixels/ SD / 16 : 9 / 30fps

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: FHD and HD use the same aspect ratio of 16:9.  For SD format, the aspect ratio is 4:3.

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:

- My camera doesn't allow me to shot in manual.  The shutter speed is 1/30 seconds.

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

             answers:

-

    

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:

-The only camera setting that I can use is video mode and I can't adjust the exposure on it.  

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:
-It permits me to manually focus.  

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

answer: 5.6 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

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

answers: When it first came out, the sensor had a problem, it had a lot of white dots on the sensor so they had to do a recall and when it was fixed they'd give it back to you.

Variety of tones

a) For my high-key image, most of the pixels fall on the right of the histogram.

b) No, there aren't any pixels in the high-key image that wouldn't print with detail.  

c) For my low-key image, most of the pixels fall on the left of the histogram.  

d) No, there aren't any pixels in the low-key image that wouldn't print with detail.  

e) For my varied tones image, most of the pixels fall on the right of the histogram.  

f) No, there aren't any pixels in the varied tones image that wouldn't print with detail.  

g) No, because the histogram on my camera doesn't correspond to the one on Lightroom so I think that the settings on my camera aren't properly adjusted.  

h) The varied tones shows the most dynamic range because the gamut takes up the whole histogram and it isn't too high up meaning that there aren't any strong highlights.

Deep depth of field

Shallow depth of field

Lens Depth Distortion

      Wide Angle 

• 18 mm (28 mm equivalent) 2-3 meters from the people 
• Lockers are stretched and give an allusion of leading to somewhere
• Distortion of the floor, lockers and background.  
• Subjects are taller from the distortion.

    Telephoto

• 55 mm (80 mm equivalent) 2-3 meters from the people
• Lockers are compressed.
• Less distortion of the floor, lockers and background.  
• The subjects seem smaller from the lack of distortion.  

Wide Angle

• 18 mm (28 mm equivalent) 2 meters from the object
• The background is far from the object and the space behind the object is wide and spacious.  
• Distortion of the floor, object and background.  
• Objects are bigger, taller and more stretched.  

Telephoto

• 55 mm (80 mm equivalent) 2 meters from the object
• Background and objects are close and compressed. 
• Less distortion from the background, floor and objects.  
• Objects are smaller and compressed.  

When you go from a wide angle lens to a telephoto lens, the width of the background is smaller and has less distance.  It also comes closer to the object which creates a compression and a lack of distance.  When the subject is expanded and enlarged, it looks taller and longer.  An object that's contracted and compacted looks smaller.  

White Balance

White balance: Auto White Balance

ISO 400 f/5.6 1/100 seconds

White balance: Daylight

ISO 400 f/5.6 1/100 seconds

White balance: Fluorescent 

ISO 400 f/5.6 1/100 seconds

The colours go from warm to cold in each image.  They also go from a neutral colour to a orange and then to a purple pink environment.  

Wrong white balance: Cloudy

ISO 400 f/5.6 1/100 seconds

This white balances gives a very warm feeling, the model has a very warm and content facial expression which corresponds with the warmth of the white balance.  Although, the saturation of the white balance is too strong and doesn't go with the environment.  Usually, for this kind of portrait, the colours should be more neutral.  

Noise Reduction

Low Noise ISO 100 F/5.6 1/320 seconds 

 Standard Noise ISO 100 f/5.6 1/320 seconds

Strong Noise ISO 100 f/5.6 1/320 seconds

Low Noise ISO 800 F/5.6 1/2500 seconds

Standard Noise ISO 800 F/5.6 1/2500 seconds

Strong Noise ISO 800 F/5.6 1/2500 seconds

Low Noise ISO 6400 F/13 1/4000 seconds

Standard Noise ISO 6400 F/13 1/4000 seconds

Strong Noise ISO 6400 F/13 1/4000 seconds

Every time my ISO goes up, the noise increases.  But with the use of strong noise reduction, it reduces the noise and detail by a lot.  I would use this method to reduce the noise reduction in my images because it's very helpful for when you take pictures in the late afternoon.  The best noise reduction setting that reduces noise without losing sharpness is standard because it takes a good amount of noise away but also maintains the sharpness.  

Lab 2

ISO 400 f/18 1/100 seconds

Camera settings:

ISO 400 f/3.5 1/40 seconds

Camera settings:

ISO 400 f/11 1/4 seconds

Camera settings:

ISO 400 f/22 1.0 seconds

In the first image, the background is soft.  This creates a lack of information and detail.  For example, the time written on the clock is unclear.  In the second image, the background is still soft but less than the first one.  The information and detail are starting to become more clear. The numbers on the time are more legible.  Although, the shaping of the numbers aren't clear enough.  In the last image, the background is sharp and clear.  We can see all of the detail and information everywhere in the background from a small aperture.  

Camera settings:

  ISO 800 f/22 1/40 seconds 

Camera settings: 

ISO 200 f/5.6 1/160 seconds

The background is blurry and has a shallow depth of field.  With a bigger aperture, the background and the subject are closer together.  It creates a flatness to the image. With a smaller aperture, the image has more distortion and we're able to see the the subject and the background separately.  The background has a deep depth of field.
