final report - Industrial portrait





Final Report – Industrial Portrait

1-    We changed : the flash is the main, using the available light and another flash as fill.
2-    We worked with a 50 mm for the portrait, it gave nice blur for the background but kept the proportions
3-    Aperture were at 2.8-3.5. We make sure the machine and the subject is on focus
4-    Speed : 1/125 of a second
5-    We had enough avail. Light but it was too flat.
6-    We had enough strobes
7-    Not too much light but I think the main light is a little bit too hard for the final result
8-    White balance and contrast, and cleaning the machine because it was really dirty and we couldn’t clean it more.
9-    Color balance : green gels and grey card
10- Next time bring more green gels


I think the challenge in this assignment were the fact that we were not sure about how to deal with the light because we did not had a pre-light test. After all, we put the fill light bouncing on the ceiling because it was created hard shadows on the subject and on the machine. Using the ceiling was diffusing the light all over the machine. We tried the main light on the side, but found that the light were really flat. We installed the soft box maybe 5 feet’s away but in front of the machine; it create like a kick light and give us more of textures of the skin and hair of the subject and less flat light.

The gobo using the black curtains went really good. The polarizer filter was also a great idea, killing the big reflexions of the neons on the top of the machine.

The things I would like to adjust if I return:  bring more gels to correct the light.

Pre light report - assignment 4 - Industrial




Pré Light Report

1.       We want the available light as main, to fell more the environment. We going to use one/two strobes as fill only to have more details on the person and on the bottom of the machine. We won’t need a light for the background because we won’t see it much. We tought about a softbox, but I think maybe a light on the subject will give us details without touching the machine (causing shadows)
2.       About 50 mm to have more perception of the environment.
3.       Aperture: 2.8 will throw out of focus and accentuate the attention of the viewer on the subject and the part of the machine he is working with.
4.       The shutter speed will be 1/125. We cannot do a long exposure to have movement because the person that is working on the machine does not move a lot. 
5.       It will be preferable to have a shutter speed faster but the available light if not strong enough. We need to work on a tripod
6.       We do have enough strobes because we want to keep the main light as main. It’s just to give more details on the person and the bottom of the machine is really dark. We will try first with reflectors. If it doesn’t work, we will use a second fill light
7.       Not too much light....
8.       The white balance will be an issue (put some green gels) and also reflections by the avail. Light and probably strobes (on the little window and on the top of the machines) we will use a gobo for the window and a polarizer filter for reflection (in that case, we will need to increase of two stops) we will need to shoot about 400-650 ISO .... Viva lightroom3 with noise reduction.
9.       Green gels, gray card
