Lab 5 Noise Reduction

ISO100 50mm f11 4 sec

Low

Normal

High

Because my picture is well exposed and that there is almost no grain with a regular ISO100, we don't see much differences between the different types of noise reduction. There is less details in my high noise reduction though because noise reduction is like Lightroom luminance, it can reduce details if it is abusive. 

ISO800 50mm f11 1/2sec

Low

Normal

High

We can see a bit of noise in the blacks (tiny blue pinkish colour) that we were not seeing for ISO 100. We do not see it (or almost) on high noise reduction. 

ISO3200 50mm f11 1/8sec

Low

Normal

High

We do see more noise for ISO 3200. For Low, we see more than High.

Overall, noise reduction is nice to have but it does reduces details in pictures when it is too high. 

Lab 4

Part 1

ISO 3200 50mm f4.0 1/60

Auto WB

Preset Tungsten

Custom Second Trial

In my opinion, none of them has the exact colour. The custom white balance first trial failed because I used a grey card and by filling my frame with the grey card I block some ambient light. My second trial failed also because I focused on the whitest thing I could see which was the ceiling which also failed because even the ceiling was pinkish. The real colour to my eyes is between Tungsten and Auto WB. 

Part 2

ISO100 50mm F4.0 1/60

Auto WB

Preset Daylight

Preset Shadow

I feel like Auto WB did a good job there. It is between Daylight and Shadow presets. We can see in the window how Daylight is more cold than Shadow and this is normal because in shadows, colours are bluish because they reflect the blue sky so to get the original colour we have to add warmth. 

Part 3

ISO3200 50mm f4.0 1/60 Tungsten

I think that Tungsten did a good job for my orgue but for the stairs it doesn't. Although the walls are  similar to their true colours but colder, the wood seems muddy because it should be warmer. The real colours are warmer like between Daylight and Tungsten. 

Assignment 1

1. Shoot a sport.

170 mm f 2.8 1/1000 ISO 1250

For this shot, I went in the terrasse so I can be about the same high of my divers. I took maybe a 100 shots before getting one that I loved. I loved this one because it is well sharped although we can see movement on his toes. We can see his whole muscles and how bony he is. We don't see much of the face but on none of my pictures I got good cleared faces in diving movements. I cropped that photo that way because I liked the way he looks like being in the air. It was indoor so I had to use a grainy ISO. I tried a lot of shutter speed but this one was the sharpest. I risked to use a f.28 so I can have a shallow depth of field of somebody in action. I think I managed my shot. 

2. Pan a moving object.

50 mm f 9.0 1/40 ISO 2000

I made my sister drop the feather in front of the nobody's bedroom in my house until I get at least 3 in focused. I liked another one better but it was so blurry we could not recognize the feathers but it looked like a purple fire. I love the way we see the movement of the camera on the floor and that the feathers are so bright in front of a black background. The colour of the floor and the bed wood makes a nice complementation to the photo. There is a lot of empty space but it smoothly integrate the picture. I chose this one because we don't see the white door next to it. The light was coming from the stairs next to the room. The feathers were thrown at one meter from the bedroom door. I know that because of the movement, it was going to be hard to focus so I used a small aperture to increase my chances to get an image focused. It was at night so I used a grainy ISO. 

3. Shoot a night scene.

28 mm f 10.0 6 sec ISO 100

I do not have time to go out much at night because I am always working. So I decided to take a picture of my swimming pool with "all the lights" turned off at night after a long shift because I loved the way it looks peaceful. Although we do not see all of the swimming pool there, I chose that one because I loved the texture the benches gave to the picture. I also love the diagonal between warm colours and cold colours. I focussed on the diving tower. It was a night scene so I used a tripod to avoid camera shakes and I used a small aperture to get a deep depth of field. Because of the tripod I used the base ISO so I can avoid having too much grain. 

4. Shoot a portrait with a shallow DOF.

82 mm f 2.8 1/60 ISO 640

Because I used a telephoto (70-200mm) I did not need to get a big aperture (small f) in order to get a shallow depth of field. But because it was at night and there was not much light, I had to use f2.8. I had other nice shots of my sister but that one was good to show how shallow the depth of field is because we have a blurry background and foreground. I did like other pictures more but it is hard to not have camera shakes with a heavy lens like my 70-200. I also did her makeup myself. 

5. Shoot a landscape/cityscape with a deep DOF.

28 mm f 16.0 1/125 ISO 100

This is not quite the most crowded cityscape or the most natural landscape but I love the perspective of the shot. There is two diagonal intercepting each other (the stairs and the building). The sky was pretty greyish but had a tiny bit of blue which makes it less negative spaced. It is a picture of my work place again but I honestly love my work place in term of architecture and lighting. I wanted a deep DOF so I used a small aperture. It was during day so I could use a fast shutter speed with a ISO of 100 and not have camera shakes. I also took other pictures which were landscape but I though that there was too much negative space into them. This one has no negative space and has perspective and this is why I chose it.

Part 1

Still Life
ISO 2500, f5.6 1/200

28 mm

50 mm

200 mm

It is impossible to get exactly the same image because of the distortion. The 200 mm seems more like bringing the subject to the middle and the 28 mm seems like making the subject wider than it really is. And we can see that DOF is deeper in 28mm and shallower in 200mm. 

People
ISO 2500, f.5.0 1/160

28 mm

50 mm

200 mm

I focused always on the left eye of Bianca. We can see how blurry the face of Matteo is and the DOF is shallow in 200mm. In the 28 mm, the DOF is so deep we can see the light and details of the library and Matteo's face is almost cleared. 

Part 2

f2.0 ISO 50 50 mm 1/500

f2.8 ISO 50 200 mm 1/200

f4.0 ISO 80 200 mm 1/200

f5.6 ISO 100 28 mm 1/100

f8.0 ISO 200 28 mm 1/100

f11.0 ISO 500 50 mm 1/125

f16.0 ISO 500 50 mm 1/80

f22.0 ISO 640 200 mm 1/40

We can see that at f22 everything is very focused and at 28 mm too even if the f is smaller. We can see also that 28 mm distorbs the images and 200mm makes the images more flat.


Part 2
ISO800 f2.8 1/125
135 mm

70 mm

28 mm

At 135mm, the DOF is more shallower but the cross seems more important than at 28 mm where the DOF is deep but the cross seems less dominant.

Still Life

f 2.0 We can see how blurry the background and the foreground are and even the glasses are not very sharp anywhere. I focussed on the thing that keeps the glasses straight on the nose and it seems that the metal circles are not sharp although they are almost at the same distance as the thing. The middle ground is focussed. Therefore the DOF is shallow which makes the image more dimensional.

ISO 100, 50 mm, f 2.0, 1/320

f. 5.6 There is blur in the foreground and background but the glasses look more sharp than f2.0 We can at least see the metallic round at the right corner of the glasses. It is not as commercial as f16 and not as artistic as f2.0 but it is more appropriate than f2.0 if we want to sell them because of its more deep DOF.

ISO 100, 50 mm, f 5.6, 1/40

f16 Everything looks in focus although I did not change the focal point, therefore, it is a deep Depth of field. It is not as artistic as f2.0

ISO 100, 50 mm, f 16.0, 1/5

Portrait

f1.4 The DOF is very shallow and we see that her eyes are sharp and focus but the remaining of her face is very blur and the background (the wall lines) and foreground (some parts of her scarfs) are even more blurry. It is not the best aperture for her position.

ISO 2000, 50 mm, f 11.0, 1/40

f11 Although there is a bit of blur in the foreground and background, because I am closed to the subject, the image is much more sharper than f1.4. I can see the details in her face and hair. The DOP is deep.

ISO 100, 50 mm, f 1.4, 1/125

Architecture

I used f16 because I cannot go smaller with my lens. The image is very sharp and focused everywhere but it makes the image flat.
