From my point of view - or how I use my gels - there are two main usage points: Adjusting a color to get a color effect. For example make your flash-light red/green/... to get a interesting background color spot. Adjusting flash color to the color of ambient light, so that your picture have only one color of light. If you have different light-colors in one ...

Yes, their main purpose is to have different colors on different lights. However in the vast majority of cases (if not always) you simply cannot reproduce this setup in post. The human eye is quite good at detecting natural light falloff and it will detect the things which are Photoshopped, especially if we talk about a setup with multiple lights (we ...

I can see two possible ways this shot was done: Light was injected where the cartridge would go. We can't really see what is back there in the picture. Some LEDs could have been carefully placed inside or almost inside the gun, and the wires run so that they would be obscured in the picture. A beam splitting mirror was used. The camera was looking thru ...

A regular softbox is not going to fit on this type of light. They are designed for strobes with a single bulb which acts as a point light source and attach via a small hole in the back. This light seems to consist of a series of florescent tubes and is thus a much larger lightsource to begin with, and will be pretty soft in it's standard configuration. You ...

If light colors don't match (or you don't want them to match and they do) then you can't correct for this in post. Lights interact with each other and there is no good way to tell which light is contributing where in a reliable and automatic manner in post. This means that you can not adjust the color characteristics of an individual light after shooting. ...

The photographer shows and discusses his lighting set up here: https://www.flickr.com/photos/29689383@N02/5615386358/in/photolist-9ydjJb Also, he mentioned elsewhere that he uses focus stacking.

Umbrellas work just fine with speedlights. The light from a speedlight is not too directed for that, especially if you use white umbrellas which will spread the light more or less independently of which direction it came from. I will echo James's comment to check out Strobist.com for info on how to make good use of off-camera speedlights. The most useful ...

This is just a guess and may not be the way these photos were created, but one way to produce such a shot would be with a mirror lens. A mirror lens is a catadioptric system similar to a Schmidt-Cassegrain or Maksutov telescope. All of these systems have a fairly large secondary mirror placed in the center of the main objective lens and all of the light ...

One main reason color gels are used on flashes is to match ambient lighting so that white-balance correction doesn't become a post-processing nightmare. When you use a flash, the color temperature of the light that comes from the flash is often different from that of the ambient lighting. And the mixed sources of lighting will both hit the same subject and ...

Compete with sunlight? Sure, easily, especially in shade. My 600EX-RT through a small soft box is still sufficient to compete with sunlight and give primary lighting from the flash if I want it to. The key is to a) be close enough and b) shoot fast enough. A flash is not sustained light, it is very intense light for a very short time. The longer your ...

When reverse engineering a lighting setup always apply the principal of Occam's Razor: among competing hypotheses, the one with the fewest assumptions should be selected http://en.wikipedia.org/wiki/Occam%27s_razor Before introducing exotic lenses or beam splitting mirrors, let's examine the requirement for the incoming light to be perfectly aligned ...

Another possibility is that it could be actually two exposures edited into one. For the hole, a long exposure could be used that captures the ambient light and from the tip outside is a regular exposure. It could also be a very long lens with two or more light sources on opposite sides of it to avoid shadows, again with two exposures, because the rest of ...

Feathering light means you use that area of tonal transition from the highlights to the shadows created by the edge of the light modifier. The technique is most easy to achieve with softboxes and beauty dishes because there’s a sharply defined edge to the modifier itself. That’s also why feathering light with most lighting brollies is less effective because ...
