Broad side and Short side, were taught to me as Fat and Thin. As fat people tend to look thinner when lit with Thin ( Short) lighting.
Lookout! The politically correct will be chasing you about fat and thin comments. Did you see how many people were bent out of shape the other day because some New York store had a mannequin with ribs showing? The store had to take it down and issue an apology!
What you are shooting, why you are shooting and where you are shooting, all have a bearing on how you light or don’t light.
Outdoors bounce can be a challenge, and if you are moving around a lot, light modifiers will need assistants to move and position them, as well as to keep track of gear. On camera flash may not look as good, but it is way more efficient when you are by yourself. Being a fan of toys, here are a few options.
Starting at the inexpensive end of the scale, a piece of paper and an elastic band from the produce isle of the grocery store. Wrap the paper around the side and rotate the flash. Works great, gives good catch lights, needs a ceiling, preferably a white one.
If you get the Canon 600 EX RT flash, it comes with a little plastic holder and a couple of CTO gels in a case. You get full and half CTO. It may be possible to get others. If you use these gels, the camera can figure out a gel is in place and it sets the white balance accordingly.
Moving to a slightly more expensive option, this is most of a vinegar jug with the label removed. It is held in place by a Velcro cable tie, available in rolls of 50 from Home Depot, they probably run around $0.08 per tie. The jug is free if you use as much vinegar as we do. This still works great with a white ceiling but will work without one. Efficiency can be improved by gluing some tin foil to top, sides, and back, that’s the extra cost option.
I like the vinegar jug option because it is easy to carry, the flash fits inside, even in the Canon case, though it is shown here without the case. It takes no extra space in the camera bag.
You can use the real Gary Fong Light Sphere, but I find it difficult to fit in my bag, so it lives in a drawer until I want to show it off like this. I think it was a total waste of $80.
Rogue make some items that seem more useful, or at least that are easier to carry. This is a small bounce card, it has an extra piece that can turn it into a snout, or that can cover the white part. It is held together with Velcro.
Rogue makes several sizes of their bounce card, they call this the Large size
The blue pieces up the back are stiffeners. The large one is big enough to be rolled either white or black side in, to make a snoot
For a slightly softer look, they make a cover for the bounce card
For more specialized effects, they also make a grid that has adjustable spread and does not take much space in a bag. The pieces can be combined to give 3 different spreads.
I like their grid because the light is pretty round
And, that’s the end of my little show, so I will finish with a shot showing what was lighting most of these shots
