I read a fair amount of books, blogs, and listen to several podcasts on photography. A common thread these days seem to be a thirst by many readers and listeners for formulaic “how to” information. As if photography was a “one size fits all” activity. It’s not. Photography is creativity, and you can’t put a formula on creativity. Photography is art, and again, you can’t put a formula on art. But like, art, there is a technical side to photography. In order to paint you need to learn how to mix colors, and handle a paintbrush, and take advantage of the type of media you are painting on. Similarly photography has shutter speeds, aperture, ISO, and depth-of-field that photographers must master to excel in their craft.

The popularity of this “how to” information clearly shows that photographers are eager for information about the basics. However, many never really move beyond the basics because they become overly concerned with the technicalities of taking a picture. Shutter speed, aperture, ISO, depth-of-field; how do they all relate to one another? How do I know which variable to change to get the image I want to create? This is where the majority of hobbyists get stuck, in the details. So books and the Internet have tried to fill this gap with information and tutorials. Magic formulas for given situations. Many do a great job of teaching you how to take a shot under given set of conditions, but few venture on to explain why. Therein lays the problem. It is easy to explain “how”, but a lot more difficult to explain the “why”, because “how” is technical but “why” is purely creative. It is in understanding the “why” that lets a photographer move beyond the basics.

A famous artist can teach you how to create a brush stroke, he may not be able to impart to you the creativity needed to take full advantage of using that painting technique. It’s much easier for him to simply have you create a similar image along side of him so that you can experience the same circumstances and learn when he uses that particular brush stroke. Through having shared experiences he hopes that you will pick up on his creativity. In photography you can’t always share the experience with an expert. There are many who offer workshops, but often they have equipment that is different from yours. Also, is a one, two, three, or five day workshop enough to move you beyond the basics? It’s probably not, at least not enough to overcome old habits.

So what’s a struggling digital photographer to do? We’ll here’s the secret to moving beyond those basics, practice. That’s it. Forget about creativity for a while. Forget about trying to get images similar to those of a photographer whom you admire. Spend a few weeks, just practicing the basics. Start with one variable at a time. Lock in the rest, and go shoot. Spend a day changing only the shutter speed. See its effects. Do the same for aperture, then ISO, etc. In this way you are creating your own experiences, and learning each variable on its own. By seeing what each of these items do on their own, you will get a feel for how they each affect the final image. Soon you’ll find that your creative side will take over, and it will combine all of these variables and start creating images the way you intended them to be.

You see, too much is made of the interrelation of shutter speed, aperture, ISO, and depth-of-field. Many people have trouble with these concepts because they are trying to understand it from a technical point of view, when it’s not. The individual pieces (shutter speed, aperture, ISO, depth-of-field) are technical. So you need to understand what each does individually. However, how they relate to one another and how to use them together is purely creative.

Well things don’t always turn out the way you plan them. I’ve been at home sick for most of the month of May. My daughter brought home a cold that only lasted about five days for most people that caught it, but for me it turned into a throat and upper respiratory infection that kept me indoors most of the time. On the upside, I finally got to finish a couple of those X-box games that have been sitting on my shelf. The downside is that the gallery has been sparse lately.

However, another upside to all of this is that I’ve had some time to work on re-launching the Everglades Photographic Society (EPS) website. There are three fantastic articles on the site by fellow EPS members, for you to read and comment on. I will be publishing several articles on photography on the EPS website later in the year, and if things go as planned I will be producing a couple of video tutorials as well. At this time we hope to have regular updates every other month, so look for all new material on the EPS website again in August. Don’t forget to comment on the articles and let us know what you think.

As many of you know I work at a university and recently I’ve had a preview of a brand new image processing system that threatens to get rid of blurry images forever. Developed by Professor Alfred Raguboboli, Ph.D. from the College of Engineering; newly patented software will be made available as a plug-in for Adobe Photoshop Extended.

Combining the flexibility of RAW image processing software and 3D rendering technology used for Hollywood special effects, new software can compute the ideal focus for an image. The software starts by examining the EXIF data stored along with a digital photograph and determines the lens, focal length, and distance to where the camera locked focus. Using the RAW image data of the out of focus picture the computer calculates the ideal focused image and exposure and then renders it. This software is so powerful that it can even compensate for motion blur and camera shake.




Professor Raguboboli has been a pioneer in developing computer rendering systems that generate photorealistic simulations of the real world. His software has been used by the motion picture industry to create stunning visual effects for such films as Jurassic Park and King Kong. The idea to extend this technology for use by digital photographers came to him after his son’s fifth birthday party. Professor Raguboboli had taken some pictures of the event with his new Canon EOS 20D, and to his disappointment, many of the images came out blurry. The shutter speeds were just too long for the low light indoor shots. He soon realized that Adobe Photoshop simply lacked the tools necessary for him to recover the images to his satisfaction. That’s when the idea struck him. The rendering software, that he had dedicated much of his time to, used a virtual camera for composition and lens effects to render scenes realistically. The idea was if you could use a virtual camera to render an image, why not the reverse? By using the RAW image data, the computer can calculate the camera’s position and focal point. The computer then determines what new focal point would render the image with the best contrast, and renders the new image based on the original camera RAW data.

All of the information necessary to recreate the correctly focused image is right there in the RAW file. There is only one exact situation that could have created the blurry image. The software simply computes the correct scene that would have created the out of focus image and then renders the correct one.

The software is so revolutionary that pretty much everyone wants to license it. There have been requests from Adobe, Microsoft, Sun Microsystems, IBM, and a lot more. NASA and the FBI would also like to use the software. “If we had thought of this earlier, expensive repairs to the mirror on the Hubble Space Telescope might not have been necessary” exclaims Professor Raguboboli.

Despite all the offers for an exclusive license to this software, Professor Raguboboli is actually a firm believer in the open source community and will release a public beta test for the whole world to try it out for themselves on April 1st, 2008. You can download the software here.
