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.
Kerry’s Quick Hit – The Sigma 50-500 lens has a tremendous focal length range which gives it great versatility. The tradeoff in this extreme focal length range is that the lens is fairly heavy.

While today’s cameras do a pretty good job when in fully automatic mode, in order to make the most of your camera you should learn how to use your camera on the manual setting. To go full manual you will need to have an understanding of shutter speed, aperture settings, and ISO speed. In this article we will get you going and get you shooting like a pro.
Kerry and David take more letters from listeners and talk about “full figure” brides, lens choices, and blog hosting and then discuss some more tales of When Things Go Bad.
In the beginning there was the original Lensbaby lens, a simple bellows system with push-pull focus and left/right and up/down sweet spot selection. Then came the Lensbaby 3G that allowed you to fine tune the sweet spot after locking it down so that you can easily repeat the same shot and settings.
Now, the Lensbaby Composer promises a lens that is easier to use, better control over focusing, and a selection of different optic inserts to give you a variety of different effects.
Kerry and Sam from Lensbaby talk about the Composer and all of the accessories that are available for it including the just announced super wide angle lens. If you are looking at getting a Lensbaby Composer, then check out our Camera Dojo special offer. For more information about Lensbaby lenses and optics, please visit them at Lensbaby.com.

Today Canon dropped two new tilt-shift lenses that update the previous models that were discontinued recently. The new TS-E 24mm f/3.5L II offers enhanced functionality and image quality in its most popular tilt-shift focal length. Designed with UD glass to minimize and compensate for chromatic aberrations and specially coated aspherical elements for the highest possible glare-free image quality, this tilt-shift lens features an angle of view of 74Â°. New TS revolving lets users freely combine tilting and shifting within the range of +/- 90Â° in the direction of movement.
This WPPI (Wedding and Portrait Photographers International) has been a great show already with tons of great speakers, two huge ballrooms of vendors, and lots of great networking with other photographers. Unfortunately you can’t be in multiple places at the same time so you have to pick and choose which speakers to go see.
Based on comments and emails I have received there are still some people that are confused about how the three elements of exposure play together to determine how dark or bright an image is. Today I want you to think of the three elements of exposure as the three points of a triangle each having an equal effect on the final exposure of the image.

Do you have dreams of shooting a Canon 1Ds Mk III? The new Canon 5D Mk II? The Nikon flagship D3X? Or how about shooting with a $1,600 70-200 IS L 2.8? If you are like me, that’s pretty much all we can do is dream about the day we can afford high end gear like that. Rentals are always a good option either since most places require a deposit equal to the purchase price of the equipment.
Firmware update Version 1.1.1 incorporates the following fixes and improvements.
1. Fixes a malfunction that in rare occurrence causes a low battery indication to be displayed when using the EF 85mm F1.2L II USM lens. Depending on the battery check timing of the camera, the battery level displayed on the camera’s LCD data panel may shows Battery will be exhausted soon or Battery must be recharged, even though the battery capacity is sufficient.
Oh Canon 5D Mk II, how doest I love thee, let me count the ways. That could pretty much sum up my impressions of the newest camera from the folks at Canon but it probably doesn’t tell you what you really need to know. I certainly don’t have the testing lab that DPReview or Popular Photography has to tell you all the little specs and test results, but as someone who is shooting all the time, I figured I would get my hands on one and see if it really is all that it is hyped up to be.
Focal Point is OneOne Software’s newest Photoshop plug-in that allows you to create images with selective focus and edge vignette effects. Using these techniques you can guide the viewer’s eye to the spot in the image that you want them to look at. Using an easy to use “focus bug” you can control the sweet spot, the amount and kind of blur. These types of effects have only been possible with expensive specialty lenses before. Does Focal Point deliver on the goods? We decided to try it out for ourselves and see what we thought about it.
