I thought I would do a little photography 101 slash book review for this Saturday’s post. Only one more week before Auburn opens the 2011 football season so today is sort of the last “free” day before the fall goes into full swing, so to speak. The changes in photography over the last 10-15 years has been amazing to watch, and I’m glad I started shooting when film was the only option. Just about anyone can pick up a digital SLR today that is capable of taking photos that weren’t even possible a few years ago. Thankfully, it still takes more than just a finger pushing a button to take shots that look like more than just vacation photos. It’s quite possible to take great shots with a point-n-shoot and lousy shots with a professional camera (my nephew who is 12 takes amazing shots with his $150 Canon PowerShot SD1300).
One of the aspects of photography that attracted me to the art years and years ago was how easy it was to take a photo, and how hard it was to master the art. Just like anything worth doing, it takes a lot of time, study, experience, and a determination to get beyond the basics. One of the very basics of photography, and also one of the most difficult to master, is exposure. There are three basic elements to exposure in photography that make an image possible. These have never changed since the very first piece of film was exposed to light. For a “proper” exposure you need a combination of aperture (lens opening), shutter speed, and ISO value (film or sensitivity speed). Today’s cameras all have what is called a “P” or “program” mode that automatically calculates all three of these in an instant and creates what it thinks is the proper exposure. The only problem with that is the meter always exposes for a “middle grey”, or average, which attempts to take every lighting situation in the frame, average it out for medium, and that’s the “proper” exposure. That not necessarily bad, or wrong, and it’s probably how about 90% of all images shot are taken, but it also doesn’t always make the most exciting photograph either.
The two examples above I shot in the fading sun over the Atlantic, and both are considered to be improperly exposed according to the camera meter at the time. One is significantly “over exposed” (too light or bright) and one “under exposed” (too dark). I took several shots back to back and the “properly exposed” shot was quite boring. I love how both of these shots show a different mood and many different details. What often determines a “proper” exposure is what you are trying to create when you take the shot. What story are you trying to tell often determines what exposure best portrays your vision when you pull the trigger.
If you are interested in learning more about exposure and how light is used in creating an image I recommend the updated edition of Understanding Exposure: How to Shoot Great Photographs with Any Camera by Bryan Peterson. I have no affiliation with Peterson but I did read his first edition that came out many years ago and recently finished the updated version published last year. Peterson goes through an easy to understand explanation of how to best use exposure in your photography beyond just pulling the trigger. Anyone who is interested in improving their photography should start off with Peterson’s book and move out from there, it’s a great place to start.

As I mentioned in my blog post last night we were going to try to get some shots of the Milky Way Galaxy, and these above are what I ended up with last night. There are so many different aspects of creation but this one always blows my mind. I love how Paul puts it in Romans 8:20-25
…ever since the creation of the world, in the things that have been made. So they are without excuse. 21 For although they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened.22 Claiming to be wise, they became fools,23 and exchanged the glory of the immortal God for images resembling mortal man and birds and animals and creeping things.
24 Therefore God gave them up in the lusts of their hearts to impurity, to the dishonoring of their bodies among themselves, 25 because they exchanged the truth about God for a lie and worshiped and served the creature rather than the Creator, who is blessed forever! Amen.
The lights at night out where we live are always interesting. Some nights it’s so dark you really can’t see your hand in front of your face, but most of the time we have a good bit of “glow” from Auburn-Opelika on one side and several other cities on the other side, but they are farther away. The shots of the Milky Way above (the first three) were taken when it was very low in the night sky facing south east. Turn around and you see the difference between the glow facing south and the glow facing Auburn. That last image still shows a good bit of stars, but nothing like the shots from the other side of the sky, and that shot was an entire f-stop longer (in other words the shot in the direction of Auburn let in twice as much light as the shots facing the Milky Way and showed less stars). Still, either way, the number of stars visible is always just amazing to me. Thanks goes to my nephew Jake who stood in and modeled for the first shot and explained to me what I was looking at in the night sky.

If you have been following the progress of our tree and tree swing, it now has just about no leaves on it at all, so last night I decided to take advantage of the very dark night out here and do a long exposure of the tree showing the North Star. This shot was a single frame, 3 hour exposure with another 3 hour noise reduction process. I started the exposure when I went to bed and it finished around 4am. Showing star trails are a little easier with a film exposure but this one turned out pretty good. The tree looks like it is leaning over to the side because it was shot with a 14mm lens pointed almost straight up at the sky. I am actually standing about 5 feet or so from the tree.
You can just see the North Star behind the right side of the tree. I couldn’t actually see it when I setup the tripod and I was just shooting for somewhere close to the center of the frame. Missed it to the left by a little but close enough.
The tree is the same one you see in the previous posts, here, here, here, here, and even here. Some day I will put all the tree shots together in one post. It is pretty neat to me to see the changes in one single location, sort of like a very long time lapse. For those of you still wondering, no, I did not sit out there all night with the camera, I just set the exposure time to 3 hours and hoped that a deer or other large animal didn’t tip over my tripod.
