Gearbox!

I quite often get questions about what kind of gear I use. I'll happily tell you all, but first I have to get on my soapbox.


The most important piece of gear you will ever have in photography, is the gray thing sloshing around in your noggin! Gear is just a means to an end. Great photographers can create great images with cheap gear and horrible photographers can buy all the gear they want and it won't make any difference!


Here is the gear I use at almost every wedding:
-Canon 30D & 20D cameras
-Tokina 12-24 f4
-Canon 17-55 f2.8 IS
-Canon 50 f1.4
-Canon 85 f1.8
-Sigma 70-200 2.8 HSM
-Pocketwizards
-Canon 550EX x2
-Canon 580EX
-Lightstand

I have a whole bunch of other stuff that I sometimes use, but this makes my main kit.

Good Article at PhotoEdu!

Jerry Frazier has a great article about the cost of doing business and how to do business with the opportunity to make a profit at his PhotoEdu blog. You don't have to constantly buy new gear to get great results!

Back to Basics - 3 Camera Settings for Rockin' Exposures!

There are so many bells and wistles on cameras that people get lost. It is a great example of how adding capabilities makes things more obscure. I recently bought a camera that is around 50 years old. How few buttons and features there were on the camera really made me realize how complex a digital SLR really is.

On this camera, there are three settings - aperture, shutter speed and focus. Because it has no built-in meter, getting the correct exposure was a little bit of guesswork for most people. With film, though you could be pretty far off and still get a decent image.

When everything is stripped down like this, you can see that there is really only three setting that you need to get a proper exposure, plus you need to focus the camera. Everything else is extra or bonuses.

The three settings you need to take control of on your camera are the basics, that we talked about above, plus the ISO (it used to be called film speed, but, since film is optional these days, let's call it ISO). The ISO is what people forget they can change.

Shutter speed controls the amount of time the sensor/film is exposed to light. Aperture or f-stop controls the size of the hole at the back of the lens. ISO controls how sensitive the sensor/film is to light. With film, you are basically limited to what it says on the side of the film box (there are other options, but that is far more advanced than we are talking now). With digital, the ISO can be changed anytime!

The effect of changing shutter speeds
When your shutter speeds are slow, you will see blur in fast moving objects. A faster shutter speed freezes the action. Also, if your shutter speed gets too slow, the shaking of your hands will cause the entire photograph to become blurry. For a good rule of thumb, try to keep your shutter speed at 1/60 of a second or higher (1/125, 1/250, etc.) with a normal lens. With telephoto lenses you will need faster shutter speeds.

The effect of changing apertures
The aperture controls what is called "depth of field". Depth of field is how much of the photograph will be in focus. We are all familiar with depth of field, but we rarely think about it. Ansel Adams liked a lot of depth of field. He wanted everything in his images to be sharply in focus. Most fashion models and many portrait photographers like the opposite. They want their subject to be sharply in focus, with the background becoming extremely blurry. That way, when someone looks at the photograph, they notice the person rather than the background. A wider aperture makes for more background blur (1.4, 2.0, 2.8), which you can see with much of my work. A smaller aperture provides more of the image in focus (8, 11, 16, 22, etc.).

The effect of changing ISO
Changing your ISO also has a significant impact on your images. Lower ISO speeds provide finer detail, smoother gradations, more vibrant color, and greater exposure latitude (exposure latitude is a fancy way of saying that you can screw up more and come up with a good image). Higher ISO creates more noise or grain. So it seems obvious that the lower ISO's are better. Well, that is true for most cases, but, when you have very little light to work with, or you are trying to create a particular look, higher ISO is the way to go.

How they work together
Okay, so all of this is fine and dandy. It's pretty simple to understand. Now, how does it all work in the real world?

I'll start by explaining how I work. I love shallow depth of field, vibrant colors, sharp b&w's, and high ISO's. The shallow depth of field makes whoever I am photographing stand out from the background. Vibrant colors and contrasty b&w images are fairly self-explanatory. I prefer that images have impact rather than being subtle. I love high ISO's because they allow me to take photographs that I might not be able to get otherwise.

I keep my cameras at apertures around f2.8 or lower most of the time. The exceptions are when I am taking scenics and when I am photographing groups. At these times, you need more depth of field to make all the important stuff be in focus. That means the things that change more often are shutter speed and ISO. They change according to the light level that you are shooting in.

If shutter speeds get too high (above 1/1000 of a second unless I'm already at ISO 100), turn down the ISO. If they get too low (below around 1/60 of a second with a normal lens), turn up the ISO.

Of course, this a vast over-simplification (from my point of view), but it's how I work in many instances. As always, let me know if I'm speaking a foreign language (photogeek), and I'll try to say it again in English!

The steps to a photography business - the short version!

Start by taking stock of what you have and what your goals are. What are your assets? Money, time, etc. How are your images? Fantastic, needs work, true beginner. Where do you want to be in 1 year? 3 years? 5 years?

My answers would go in this order:

1) Get what you need in the way of equipment to produce good work. This does not need to be the flashiest of gear (a 50 1.8 or 35 f2 could be a big improvement in creating a "different" look on the cheap as would a 85 1.8). A vivitar flash and some pocket wizards (or generic alternative) can create dramatic results in the right hands as Zach Arias has often shown. Also get something wide (20mm on 5d or a 12-24 f4 tokina on a crop camera) to add drama and see things a different way. With a couple of these suggestions, you can be producing a wide variety of different looks and have spent less than $1000. It also works as a backup strategy if something breaks.

2) Educate yourself in creating amazing images. One Light is a good place to start. As is the usual $100 Denis Reggie tour, or if Huy is doing a short course in your area. There are also many online resources. Second shooting for great shooters would work very well.

3) Once you know how to take amazing images, are inspired, well-equipped to take advantage of the opportunities you have or will get, and have a website capable of showing off your work in a up-scale, stylish way, then you can pour some money into advertising.

It is hard to work up a buzz as an average photographer, so educate yourself, equip yourself, produce some excellent work, THEN attack the marketplace. Spending money on advertising before you are ready is just wasting money. Getting yourself in position to attack the marketplace makes more sense.

What you have in the way of assets (namely time and money) will determine your strategy for the attack and the timetable involved. If you have more money than time (full time well-paying job and a family for example), spend the money on the best possible samples and advertise in the biggest, splashiest places. If your assets are more on the time side (part time working bachelor), then you might get a couple nice samples and try to get your name out by meeting everyone that will meet with you (florists, planners, venue coordinators, other photographers, etc.).

Canon Lensmaking!

Okay, this is photogeek heaven! Check out how lenses are made at Canon!

Camera Gear - Lenses!

Here are some recent questions I've had about camera gear and my answers. I know what I'm trying to say, but if anything is unclear, please let me know so I can fix it!

I want a better lens, what should I buy?
There are so many different ways to answer this question. Most people start with a crop camera (something besides a Canon 5D or 1 series) with a kit lens. Pretty much any lens you buy will be an improvement over that!

50mm fixed focal length lens. Beginning photographers often overlook this lens. However, it is one of the sharpest lenses you can buy and it is a very good value. Both Canon and Nikon have an f1.8 version that is less than $100 (and really great versions at $300 for the f1.4). Whenever I suggest this lens, I get asked why anyone would want a lens that doesn't zoom. The simple answer is speed. A fast lens lets you take available light photographs in less light, or extends the reach and power of your flash.

The lens that comes with most kits is something like an 18-55 f3.5-5.6. What this means is that the f-stop (aperture) at 18mm is f3.5 and it slides to 5.6 at 55 mm. Lets compare that to the cream of the crop lenses that are available. The 17-55 2.8 IS lens that Canon makes is 2.8 the entire way. That means that at 17/18mm the 17-55 needs 67 percent of the amount of light to get the same shutter speed. At 55mm, the 17-55 needs only 25 percent of the amount of light. Now, let's compare even the amazing 17-55 2.8 IS to the $80 50 f1.8. The 50 f1.8 needs 33 percent of the light that the 17-55 2.8 needs to reach the same shutter speed. Compared to the kit lens at 50mm, it needs a mere 8 percent. You can get even more light if you go with the 50 1.4 which sits at 6 percent of the kit lens, which is a significant improvement over the 1.8.

However, having a fixed focal length lens does make it hard when you want to include more or less in the photograph (sometimes this is called the human zoom because the photographer has to move forward or back). Therefore, I also recommend the 17-55 2.8 IS lens for Canon users. Nikon also makes a version, but without the internal image stabilization. These are exceptionally high quality lenses that are capable of creating amazing images in the normal (for a crop camera) zoom range. If you can't afford the Canon/Nikon version or if this is just one of many hobbies, I have heard good things about the Tamron 17-50 2.8. When you switch from one the kit lenses to one of these, you will suddenly start seeing an increase in good photographs. Those using a full-frame sensor (5D & Canon 1 series), I suggest the 24-70L.

In addition to the light gathering advantages that these lenses offer, they also produce more "out-of-focus" areas. This is a huge advantage. Many photographers, like myself, love this. It enables the photographer to isolate the subject from their surroundings.

This photograph of my daughter's friend was taken with a wide aperture to make her stand out from the background

A lot of people also want to be able to take photographs of their kids sporting events. Depending upon the type of sport, you will need different equipment. For inside sports such as basketball and gymnastics, I would recommend the 50mm 1.8 (or 1.4 for a better built lens) or the 85 1.8 (or 1.2 if you have an extra $2000 to invest in your hobby). For outdoor sports, it's hard to beat the 70-200 zooms. The Canon 70-200 2.8 L IS (VR for Nikon) lens is fantastic. If you don't want to spend that much, I suggest the 70-200 4.0 L or the 70-200 2.8 HSM Sigma.

The last type of lens that someone would need would be a wide-angle. These are great for landscapes, architecture, group portraits, and for creating interesting images. I personally love wide angle lenses, but I didn't so much when I was first starting. The lenses I would suggest in this category would be the Canon 10-22, Nikon 12-24 and Tokina 12-24. For those that have a full-frame sensor, I suggest the 16-35L.

Are there situations where I wouldn't want the 2.8? I was taking pictures with it on auto and sometimes it would set to 4.0 - Should I set it to 2.8? What does 2.8 really mean?

Okay, there are several related questions here, so I will start with the most basic and work my way through them.

In the simplest terms, the aperture (f-stop) number represents the amount of light that the lens allows through to the camera. Each f-stop difference means the light allowed through is half of the f-stop before it. In the olden days when I started in photography, the numbers of the f-stop were engraved on the lens, so it was easy to remember them. The full f-stops are 1.0, 1.4, 2.0, 2.8, 4.0, 5.6, 8.0, 11, 16, 22, 32, 45, etc.

This image was taken with a smaller aperture to make everything from the wood post to the Herb Farm in the background in focus

The obvious question at this point would be, "So what does that do for me?" What it means is that the lower the aperture number, the more light a lens can gather, which allows for higher shutter speeds, less camera shake causing blurry images, less need for flash, and when you do use flash you have greater range and options with your flash

Something else that changes with the aperture is the Depth of Field, or how much of the frame is in focus. If you are taking an Ansel Adams type landscape, you will want to shoot at something like f22. If you want to isolate your subject from the background, you will want a very fast aperture (like 2.8 or faster) to throw everything else out of focus.

This is another example of a shallow depth of field. Her eyes and mouth are in focus, but the tip of her nose and her ears are out of focus, ensuring that when we look at the photograh, we look at her face and aren't distracted by the background.

Next time I'll tackle the question most often asked of me at weddings, "Why is your flash pointed sideways?"
