Using your flash’s guide number

If you have ever shopped for a flash or read a review, you may have noticed a section of the spec called the guide number or GN. While this value is a measurement of power that the flash has and allows you to compare flash models, is this number useful to you at all? In this article we dig into the guide number and see how we can use this number help us dial in our flash and camera settings using some math instead of just guessing and retrying until you get what you want.

The Sunny 16 Rule in Photography

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.

Classic Portrait Lighting Styles Part I

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.

Photography Basics: Beginners Guide to Aperture

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.

Understanding Light Stops

One thing that seems to baffle a lot of new photographers is understanding the term “stop” as it pertains to a measurement of light. We see this word used over and over with regards to shutter speed, aperture, film speed, filters, lighting, and other ways that light is used. You may hear a phrase like “you should expose one side of face 1-2 stops under the lit side of the face and expose the background 1 stop under the main subject”. For many people that’s about like asking them to solve a complex calculus problem.

How to Calculate Depth of Field

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.

RAW vs. JPEG – Deciding which is best for you

Yes, RAW vs. JPEG, the seemingly endless debate, almost as bad as Mac vs. PC or Film vs. Digital and people have been asking me to write up an article on this based on my opinion and experience and I have really put this article off for a long time as I wanted to be as unbiased in how I write this given that this is a very biased topic.

Review: Tronix Explorer XT Portable Power Source 4

Review: Tronix Explorer XT Portable Power Source

Studio strobes are expensive and when you need lots of light but when you want to use them on location somewhere you have to find electrical outlets and possibly use long unwieldy extensions cords. But what happens when there is no power available at all? Using a generator is not recommended unless you can find one with a true sine wave inverter and even then, the peak times of the strobes when recycling can put an excessive strain on the generator. Innovatronix has a solution with their Explorer XT portable power source.
