Mac versus PC, RAW versus JPEG, Coke versus Pepsi, all solid battles in their own right but Adobe RGB versus sRGB is still one that confuses more people than anything else. One of the problems is that there is big name experts on both sides of this argument arguring why their side is right and the other is totally off-base. What we will try to do is to show how both affect images so that you can choose the right one for your situation.
Although you may think that no two situations are alike, the fact is that there are quite a few constants that you can rely on to give you a good starting point. The sun is one of these things you can count on to be consistent. Of course there are things that affect the sun’s output like the time of day, haze, fog, and clouds, but on a bright sunny day the light output is very consistent and knowing the camera settings for this condition will give you a guideline to make adjustments. This is where the “sunny 16” rule comes into play.
As we continue our series on portrait lighting we now need to look at the different types of classic portrait lighting and see the effect it has on someone so we can decided when to use each type. By choosing the proper lighting for a particular person, we can help them to look their best by making them appear to be thinner or wider or to accent or minimize certain facial features.
As part of our Photography Basics series we talked about Exposure already and this time we are going to cover the mystery of aperture. Aperture is probably the least understood setting of everything on your camera. While shutter settings are very easy to understand, to long of a shutter speed and you will get blurring, pretty simple stuff. Same with ISO, too high of ISO and you introduce digital noise. But learning how to use aperture properly can kill brain cells faster than a frat house kegger party.
A big stumbling block for many new camera users is how to figure out how much depth of field a particular image will have it in given the focal length of the lens, the aperture used and the distance to the subject. Trust me on this, trying to do the algebra to figure it out is not something most people want to try to do in their heads. In this article we will cover all of the math involved and then make it real easy with an Excel spreadsheet and some links to some free applications to help you out.
