Assignment 2

This image was shot with continuous lighting. I was painting with the light of my iPhone's flashlight. I set the shutter speed to 30sec. 

On this photo, I use the "bulb" function on my camera. Since I didn't have a flash, I was quickly turning on and off my iPhone's flash.

On this one, I decided to write my name with my iPhone's flashlight pointing at the camera.

Save the pixels

+1 stop

-1 stop

Well exposed (+1 stop)

1:1

Under Exposed (+/- 0)

1:1

There is less noise when the exposure is higher.

Jpeg

Raw

Theres actually less noise in the jpeg than in the raw file. I suppose there is a noise reduction process in the jpeg compression in the camera. The jpeg clearly contains less details and is less sharpthan the raw file.

In general, the Auto Lighting Optimizer (Noise Reduction) did help a bit. It also made the image a bit brighter. I wouldn't go higher than the low option as it soften the image. To be honest, I'd rather change location or the quality of the light than use this feature. Maybe it works well with some cameras, but with mine, I don't see that much difference with the low setting and the other ones are not really usable. This is why I personally wouldn't use this option.

WB

WHITE BALANCE WORKSHOP

Custom WB

Tungsten

AWB

Daylight WB preset: The cold overcast adds a nostalgic feeling to the picture
and the actual environment seems more cold.

AWB: It actually looks the best to me. Made the picture quite neutral.

Shade WB preset: Makes the image warmer. I usually prefer a slightly warmer overcast than a cool one for a portrait.

Fluorescent WB preset: The image has a cool overcast. The model looks sick...

FOCAL LENGTH - LENSES - WORKSHOP

I have a Canon Rebel t3 and I'm shooting with a Canon EF-S 18-55mm lens.

1/125 sec at f/5.6, ISO 800 (18mm)
More distortion in the background as well as on the object itself.

1/125 sec at f5.6, ISO 800 (55mm)
Less background, less distortion.

1/125 sec at f5.6, ISO 800 (35mm)
The image looks more flat and we see very little of the background compared to the two others.

1/50 sec at f/5.6, ISO 400 (55mm)
The face of the model looks more pleasing. The image looks more flat. This would be perfect for a portrait as it isolates the subject from any context.

1/50 sec at f/5.6, ISO 400 (35mm)
More context (background)

1/50 sec at f/5.6, ISO 400 (18mm)
The background takes more place than the subject. The image and the facial features get more distorted.

1/100 sec at f5.6, ISO 1600 (55mm)
At a higher focal length, with the same aperture, the DOF increases.

1/100 sec at f5.6, ISO 1600 (35mm)

1/100 sec at f5.6, ISO 1600 (18mm)
More context as the background is more in focus then the last two.

1/320 sec at f/4.0, ISO 100 (18mm)
The image is distorted and not as its sharpest.There's also more blur and vignette at this focal length.

1/80 sec at f/8.0, ISO 100 (18mm)
From all the 18mm focal length photos, this one is the sharpest.

1/40 sec at f/16, ISO 200 (18mm)
Not bad but not the sharpest. Less blur and vignette as we go higher with the focal length.

1/80 sec at f/8.0, ISO 100 (35mm)
f/8.0 seems to be the sharpest. This one is probably the sharpest of all. Still a little bit of distortion.

1/50 sec at f/16, ISO 200 (35mm)

1/60 sec at f/8.0, ISO 100 (55mm)
No distortion, the shapes actually look like they're supposed to.

1/60 sec at f/11, ISO 200 (55mm)

1/60 sec at f/22, ISO 800 (55mm)

Overall, for my 18-55mm lens, what seems to be the sharpest aperture is f/8.0 and the sharpest focal length seems to be 35mm (middle).
