Polarizing Filter
So finally the morning light in this side of the building was better than we expected. An f 8 at ISO 400 ambient light, and 1/125 sec shutter speed at 9:30am. We set up the first strobe while the model appeared, and we did the first shots with the bounced flash light on the ceiling to lit the model with a natural kind of light indoors. The indoors light was 1 f-stop lower than the ambient light (f 5.6) in order to overexpose the exterior a little bit. The only issue was the window reflection on the windows, as we were in a spot surrounded by windows in an angle of almost 180C.
The fill light was nice, the background was slightly overexposed but definitely we needed to get rid of the reflection on the window beside the subject. So, the use of a polarizing filter was essential at that point. And as usually happens when using this filter, the exposure went down in 2 f-stops. We tried to divide issues: We didn't go till ISO 800 as it was supposed to be to compensate the new exposure, but we stopped at ISO 640. In the other hand we change the shutter speed from 1/125 sec to 1/60 sec to force the background to be as overexposed as possible to pop-up our model in the composition.
After doing this, we realized that one of the sides of the model (the left side on the image) was not lit enough to have enough detail on the dark trousers and jacket. So we set up a second light, a small hot shoe flash in a 1/128 of its maximum power, aiming the model from the back left side. The light was nice and enough to add more detail on the clothes and model's head, neck and right hand.
Once the light was fine, we started to play with the model's pose. At the end, and after an important amount of images, we thought we had The Final Shot... at least one decent image to work with.
A few hours later, after downloading and choosing the images, I pick one image where the model's pose was nice but the reflection on the window was still too strong -Image A-, and another image -Image B- where the reflection was softer, and also where there was not a car passing by on the right side of the image, but where the model's pose was not nice at all. So, I took the right windows from the Image B, and I put them on the Image A after correcting the perspective and proportion (The image B was taken from an angle slightly different than the one in the image A), in order to keep the model in the nice pose and composition of the Image A.
Then I overexposed a little bit more the background to increase the ratio with the model's exposure, and I pushed a little bit the contrast on the model and the interior of the building. Finally I cropped the image a little bit to get rid of some noisy elements.
The result, a soft and natural kind of light filling the interior space with an overexposed building in the outside as a background, and a model looking through the window toward the horizon in front of him.
Pd: the model is a friend of mine who is an architect in the real life. I think that the composition, with the building in the outside as a background, and him looking to the horizon in the same direction as the building's perspective goes, works in a nice way for the purpose of the assignment, an actually could work very well as a portrait of a young architect as my friend is.
