Ok Thanks!...for the last two questions...the limits of my lighting knowledge and the gain of it will be via trial and error, no doubt about that.
I had been using one light with a softbox and a reflector. For this exercise I wanted to add a second light to see what the effect would be. So that was really the assignment, using two lights and a reflector.
Part of the setup was to try to determine proper placement of all of the elements based on rules that I knew and rules that I needed to learn following the assignment. The elements that I was focusing on were:
1. Size of softboxes
2. Placement
3. Distance to subject
4. and Metering
So what I started out with was a 3x4 softbox for the main light, but it did not turn out to be the main light due to the imbalance with the fill light which was mainly used to place some light at the background and spill over to the back of the girl by using a 1x4 strip. And add to the two lights the reflector (white) used to fill on my left. Plus that the light was a diagonal of two lights main on my right, strip at left back and reflector, left. White balance was set via custom and grey card. In this instance I was using my 17-55, therefore, extra space in the photos since there were two girls in the photos when this started and I didn't change my lens when the other girl said she was done.
Probably the biggest issue/lesson learned is the imbalance of the lights as has been pointed out and just as recent as today I may have finally understood to meter better/correctly/differently/properly.
Yet as rules apply if I start to break down some of the lighting of the photo and the effect, here is where I come out despite the effort.
1. I don't mind the horizontal, I could crop it square for fun.
2. I like the whimsical hair, I want to be able to repeat that kind of effect again but more controlled.
3. The pose was not a pose, just random movement by the girl so for me the pose and the hand has little to do with the photo exercise. (I know its killing a bunch of you all though) but I am not up to anything at this juncture more than getting the lighting sorted out but the notes on posing are good and I will carry them forward!
4. and most important to me...I don't want to take safe photos, I want to create photos that have an edge to them, like the result of the hair, so that is something that I want to be able to accomplish. This is my hobby, this is for fun, and I want it to be fun and look fun. I don't want to take a rules photo just because I have the equipment to do so or learn how to do so, I want to take a rules photo and give it some creative spark.
So there you have it. I can't tell you ho much this has helped. I have read today, all day, and I have learned a lot by sharing just this one photo and really having the notes from everyone to make me think and make me learn more to get better. Keep the kindness flowing!
