Lab 3

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.
