lab 7: save the pixels

subject 1

9252 - 20170322_
according to my camera
9254 - 20170322_
1 stop under exposed
9257 - 20170322_
1 stop over exposed

I think the first one has the better exposure – it’s not too dark/not too bright and provides a good contrast between light and dark.

properly exposed
properly exposed
one stop under exposed
1 stop under exposed

the noise is definitely worse in the under exposed image

the JPEG image seems duller and less vibrant than the RAW image. the JPEG image also seems to have less noise. other than that they both seem pretty similar.

lab 6: histograms

a. the pixels in the high-key image fall more to the right on the histogram.

b. all the highlights in the high-key image are either 95% or under so none of the pixels would print without detail.

c. most of the pixels in the low-key image are to the left of the histogram.

d. most of the blacks in the low-key image are either 5% or under so those pixels would print without detail.

e. the pixels in the varied tone image fall more to the left of the histogram.

f. there are a few black pixels under 5% so those pixels would print without detail.

g. i believe my camera is properly exposing the high-key scene, as none of the pixels would print without detail. however, i don’t think it’s properly exposing the low-key scene, as many of the pixels are below 5%.

h. the varied tone histogram shows more dynamic range.

lab5: noise reduction

both noise reductions off:

iso 100  f/18  0.6 sec. 
iso 800  f/18  1/13 sec.
iso 1600  f/18  1/25 sec.

slow shutter speed noise reduction:

iso 100  f/18  0.8 sec.
iso 800  f/18  1/13 sec.
iso 1600  f/18  1/25 sec.

high-ISO noise reduction – weakest:

iso 100  f/18  0.6 sec.
iso 800  f/18  1/13 sec.
iso 1600  f/18  1/25 sec.

high-ISO noise reduction – weak:

iso 100  f/18  0.6 sec. 
iso 800  f/18  1/13 sec.
iso 1600  f/18  1/25 sec

high-ISO noise reduction – strong:

iso 100  f/18  0.6 sec.
iso 800  f/18 1/13 sec
iso 1600  f/18  1/25 sec.

the in camera noise reduction did help quite a bit considering my camera is old and generally includes a lot of noise in the images. there doesn’t seem to be any detail lost. however, there was a loss of sharpness when the high-ISO noise reduction was on the strong setting. I think the slow shutter speed noise reduction turned out to be the best one.

lab 4: creative white balance

auto WB
tungsten WB preset
custom WB
auto WB. there is obviously two different light sources in this image: the foreground light source ( a pinker light) and the background light source (fluorescent lighting).
shade WB preset. both lights are a lot more yellow. this change is very apparent in the lights in the background (compared to the previous image). 
fluorescent WB preset. the picture is only slightly more yellow than the first of the series. the temperature change accentuates the foreground light source. 
shade WB preset on fluorescent lighting. this yellow colour cast gives the picture a lot more mood and aesthetic qualities. it also adds a complementary colour to the model’s green hair. i think the colour cast changes the image for the better (this is my favourite image from this whole post).

assignment 1: creative use of fpeed and aperture

roller derby.  iso 1000  f/1.7  1/500 sec.  because i was inside and there wasn’t much light and i wanted to capture the movement without any blur, i had to use a relatively high iso for my camera which made the picture really grainy. this made it kind of hard to edit in post-process. because of the shallow DOF, it was really difficult to keep the subject in focus and gave me lots of trouble. overall i learned that my camera is not good at all for sports photography: the highest iso possible is 1600 and really reeeaaaally grainy and the auto focus is really slow and doesn’t properly focus half the time. i really like that both the referee and the player’s name are readable because while derby is a sport, it’s a sport with lots of personality and pizzazz. so by showing their names, it shows the fun/wild personality side of roller derby.
night photography.  iso 100  f/8.0  20.0 sec. it was quite cold while i was shooting this, so i didn’t take as much time on this image as i would have liked to. however, i think the image turned out pretty good. i like that the 4 different light sources in the windows are different colours; it makes the picture more interesting, considering it’s just a house.
iso 100  f/5.6  1/320 sec. i think this image wasn’t very well planned on my part. the framing is slightly awful; calvin’s fingers are cropped and i could have made the DOF even shallower if i had raised the shutter speed which would then have helped me freeze motion better as well. however, i love the colour of the building he is standing in front of. 
iso 100  f/14  1/40 sec. i took this picture from inside the car, hence the random streak in the window. however, i really like what kind of effect it has on the picture so im happy i didn’t shoot this from outside the car. i realize now i could have raised the iso a little so that the shutter speed wasn’t so risky but it thankfully turned out alright.  

i don’t have my panning picture because i forgot my camera the day i was going to shoot it (the day before this assignment was due). however, if i had done it i would probably have chosen to pan a snow plow or something similar.

Lab 3: Lenses

For these images I either used my 35-70mm f/3.5-22, my 100-300mm f/5.6-32 or my 50mm f/1.7-22.


although the foreground object takes approx. the same amount of space in all three images, as the focal lengths got longer, the background seemed to move closer to the foreground object, making the picture flatter.



as the focal length gets smaller, the more distortion is introduced into the image: their bodies and heads look smaller.. there also seems to be a more apparent depth of field in the shorter focal lengths.



as the focal length gets longer, the depth of field gets shallower even if the number stays the same. this can be seen in the images above. the aperture i used was f/5.6.


35mm  f/4.0 the edges of the image are blurry and there is a sort of roundness (distortion) to the image that isn’t there in the images with the longer focal length.
35mm  f/8.0  the edges are less blurry. however, the distortion is still there.
50mm  f/1.7  some of the distortion has been removed. however, the edges are much blurrier than the first two.
50mm  f/2.8  the edges are slightly less blurry than the previous.
50mm  f/4.0  once again the edges are slightly less blurry than the previous.
50mm  f/11  the image is completely sharp and there is minimal distortion.
240mm  f/8.0  the edges are pretty blurry, but there is hardly any distortion at all. the image seems completely flat.
240mm  f/22  the edges are slightly blurry and there is hardly any distortion.

overall these images were all slightly different exposures which shouldn’t have been happening since my camera was on aperture mode the whole time.
