  • Thoughts on Photography

    A web site mini-essay linked here talks about the ladder of appreciation for photographic skill. This person has a very good point. It’s easy to identify what got you to a certain skill level, but it’s more difficult to see how to take the next step. It’s just like watching professional sports. “How do they do that?” I’ve played soccer, hockey, and volleyball in competitive settings. I’ve watched baseball and hockey from up close. I am amazed at the things the professionals can do. The way Wayne Gretsky could weave down the rink with the puck nailed to his stick or Chipper Jones’ ability to see the ball come out of the pitcher’s hand or Tiger Woods’ skill in dropping a tiny white ball within inches of where he was aiming. Wow. Unfortunately, as so many people understand, sports skill can be learned, but a lot of it is inborn aptitude. No matter how much I practice, I’ll never be as good at kicking a soccer ball as David Beckham. I’ll never have the same touch with the club as Tiger Woods. And I’ll probably not have the same eye as Ansel Adams, which segues me back to the topic of this post.

    I’ve looked at a lot of excellent photography. I’ve even put a few images on film (and CCD) which could be called “good”. But I don’t have the eye. Not yet.

    As with all things, practice makes better. Poking around through internet searches for “improve photos” or “photography 101,” etc. you pick up a lot of tips*. There’s the rule of thirds, effective composition, appreciating light, using depth of field, finding uncluttered subjects, understanding how your camera works… These are all technical skills which can be improved with diligent practice**.

    But “the eye” is something more difficult. It can be learned and taught, but the best of all photographers have that something more, just like professional sports players. They can see things that the rest of us do not. Not only can they see it, but their diligently developed skills allow them to capture it in that fleeting momemt before it’s gone. How many times have you thought, “Gosh that would be a good picture! Where’s my camera?” (or “I wish I’d brought my camera”)

    I have no pretentions to a level of photography that would allow me to dispaly in galleries, or submit to professional contests. However, I am working on developing “the eye.” Hopefully, the images I post to Flickr will reflect that as time goes by.

    *One of the good ideas I came across in my internet searching was: look for photos you think are excellent, then try to duplicate them. I guarantee that there will be lot of learning in that endeavor.

    **The advent of the instant-check digital camera is wonderful for improving skills. You can see immediately how well things are doing. Half of the pain with film was taking good notes so you knew what it was you set your camera to during the shots on the roll. I love EXIF information.

  • DSLR Sensor Cleaning

    As I mentioned in a blog post about a week ago, I was getting ready to clean the sensor on my Canon Digital Rebel XT.

    Here’s what it looked like before I started.
    IMG_4604 Before Cleaning

    Look at all those black spots! What a mess.

    Here’s what it looks like now.

    IMG_4613 After Cleaning

    I’ve still got some dust on the top of the image (which is the bottom of the sensor) but I can deal with this for now. I’m very leery of touching my camera’s sensor any more than I need to. This is a huge improvement over the uncleaned version, and I declare it good enough.

  • DSLR Sensor Cleaning

    I’ve learned a lot about Digital Single Lens Reflex (DSLR) camera sensors and their foibles in the last few days.

    Foible numero uno is dust. You don’t change sensors like you used to change film rolls, therefore dust that gets into the body will slowly (or not so slowly) accumulate on the sensor. If you live in a place like Atlanta that had a pollen count last week of 5,200 particles per cubic meter you may see a quicker accumulation than elsewhere (120 ppcm is considered extremely high. Yes, one hundred twenty). These dust particles will cause shadows on the sensor under the right (or wrong) conditions, leading to little black spots on your images. Not a high level of mojo, in my opinion.

    With several very helpful suggestions from the Atlanta Flickr Group I ended up at cleaningdigitalcameras.com, which describes in exhausting detail the various methods and products to clean up a sensor that looks like this.

    Image of Dust on my Digital Rebel XT Sensor

    I obtained this image by opening up Photoshop to a new (white) file, setting the camera to f/22, exposure 2 seconds. I didn’t bother with focus and moved the camera around in a small circle during exposure to avoid picking up anything on my computer screen. After importing the image, I ran auto levels and voila! Dust.

    What am I going to do about it? I ordered a Rocket Blower, Eclipse, and Sensor Swabs, with which I will clean my sensor in a week or so. Until then, I guess I’ll just deal with it.

    For information, this article analyzes the various automatic dust removal systems for DSLRs by the big manufacturers. Boils down to: Olympus’ system works. Others don’t.

  • Favorite Photo of the Week

    Squirrel Print in Pollen

    It is pollen season in Georgia right now. It’s the time of year where no one washes their car for three weeks. We’re all hoping for some rain this weekend to make everything a bit less yellow. The image above is from my front porch, where evil squirrels regularly case my house.

  • Georgia Marathon Photos

    Georgia Marathon 2007As I mentioned in my post a few days ago, I went to take photos of the runners in the Georgia Marathon today. It was a great time, and I learned a lot about taking pictures of sporting events.

    1. Make sure the battery that is in the bag as a backup is charged, too. Wasn’t a problem, but it could have been
    2. Bring more memory. I had 2 gigabytes, and it wasn’t enough by a long shot. I shot from 7:22 AM til 10:08 and we were just getting to the thick of the Marathon group
    3. Get a better lense. I’m using the kit lense that came with the Digital Rebel XT, and it sucks in low light, which 7:00 most definitely was
    4. Check my camera to make sure it’s showing daylight saving time, and not eastern standard

    I had a great time and I hope all of the runners did, too.

    I’m currently in the process of posting all ~1,400 photos I took today to my flickr accout, Georgia Marathon set. As I mentioned previously, if you’re in one of these pictures, feel free to take it with no restrictions. I’m fully licensing the occupants of these photos to do with them as the will.

    A few Notes:

    • I was standing at the corner of Saint Charles and North Highland, which by my calculations was at mile 7.6 for the half marathoners and just shy of the mile 21 for the full marathoners.
    • In order to find the photos that you (might) be in, you’ll have to figure out what time you ran by me and check out the timestamps on the photos to narrow it down.
    • I forgot to set my camera to daylight saving time, so you’ll have to add an hour to the photo time to get the actual time you ran by me.
    • 23:00 Edit:I ran out of memory at 10:08 AM, so if you passed by that location after that, I’m sorry. I’ll try to do better next year.

    If you have any questions, send me an email. If you find the photo you’re in, and you want the full-res version, send me an email.

  • Favorite Photo of the Week

    People and Grouper

    I was at the Georgia Aquarium this week with a friend and snapped this photo of a big grouper looking over the shoulder of two people. The groupers generally spend their time staring directly out the window at all of us, which makes me wonder whether they can see us or not. Those are some cool fish.

  • Georgia Marathon

    The first annual Georgia Marathon is this Sunday, starting at 7:00 AM EDT* (wow that’s early). If you’re in the area, come by to cheer on the runners! I’ll be down near the corner of North Highland and Saint Charles taking pictures (popping back and forth between N. Highland and Briarcliff). If you see me, say hi!

    It was nigh impossible to find the course map on the website, so I provide the link here.

    You might think that watching a marathon is boring, and you might find it so, but I find it exciting to cheer on the runners, especially the runners toward the back who are out there only for their own enjoyment. The energy coming off of them is contagious, and I try to share it back to those runners who need a bit of a boost.

    I will be posting all of the pictures I take of the Georgia Marathon on my Flickr account, subject to the Attribution, Non-Commercial, Share Alike Creative Commons restrictions. However, if you are in the photo, I’m exempting you from all restrictions and you can take the image with my compliments. I hope that this will provide a service to those runners who want some photo documentation of their run, yet don’t want to pay a professional photo company an arm or a leg (or both) for the image. I don’t promise to take a picture of everyone (there’ll be 15,000 people!) but I’ll do what I can.**

    I invite all photographers at the Georgia Marathon to follow my lead and let the runners have the images of themselves, with whatever restrictions you desire, for their own use.

    *I assume that they scheduled the start and forgot to account for the changed daylight saving time. 7:00 right now is just past dark and into a bit of twilight. Not exactly good running light.
    **In case anyone from any of the photography companies gets up in arms about this, I’d like to point out that I will not be indexing the photos by bib number, nor framing, nor matting, so I don’t think I’ll be impacting your business.

  • File Photos

    I wrote an entry concerning a Carl Sagan anecdote as a part of his 10th deathday memorial.

    While I was writing it, I thought it would be cool to do a google-esque change to my blog header for one day. Put up an image of the night sky, or the moon, or something spacey. Of course, I’ve only had a digital camera since 2002; I haven’t accumulated too many different types of images, especially night ones. I tend to take pictures with an eye toward inclusion in a photo album. I do have a lot of roadway/traffic related pictures, but most of them are pretty boring

    So, a new task. A quest, even! Take some pictures that are blog-worthy and useful under different circumstances. I believe the first ones I get will be night images around Atlanta. You can do cool stuff with long exposures around highways.

    Sounds like it is time to break down and get a flickr account.

  • More Google Sightseening

    Here is a Google Maps image of a cruise ship that capsized due to a typhoon. Wow…

  • Is that a lens in your pocket or are you REALLY happy to see me?

    Carl Zeiss has gone where no one has gone before.

    Wow, I need one for my Digital Rebel XT.
