When you take pictures, there are basically three things you control:
- Composition: What's in the frame
- Focus: What you're focused on
- Lighting: How much light reaches your camera
Today's cameras do 90% of the focusing and lighting work for you, which means you can focus on composition.
Focusing on story.
10% of the time, your camera does the wrong thing. This is where the quality of your camera comes into play, specifically:
- Quality of your camera's lens
- Quality of your camera's sensor
- Ability to control manual settings easily
"The Big Picture About Exposure" from the The Bastards Book of Photography offers a great, simple explanation for how to control the amount of light your camera receives using manual settings. You start with your camera's exposure setting, which essentially manipulates:
You can also manipulate these four settings manually.

A nice explanation of apertures and focal lengths, and why you can't get good depth-of-field in point-and-shoot cameras (like mine).
In general, to [get shallow depth-of field], especially w/ point-and-shoot cameras:
- Lower F-stop numbers (larger apertures)
- Longer focal lengths (zoom in)
- Get closer to the subject
I have a Manfrotto 293A3-A0RC2 tripod with a ball head and QR plate. More on tripods here. I also have a Joby GorillaPod.
I have a Yongnuo 560 III and RF-602 wireless trigger. I may want to get some gels.
Digital cameras have limitations on video length.
I use Adobe Lightroom for editing and photo management. There have been some suggestions that Olympus Viewer will render the RAW files more effectively than Lightroom, and that you should process RAW in Olympus Viewer, generate 16-bit TIFFs, then import those into Lightroom for processing and management. I've compared the two, and I haven't seen any differences in the rendering. Others have questioned this as well and have pointed out other tradeoffs.
I'm experimenting with exiflow for managing my digital photography workflow (renaming files, metadata, etc.). F-Spot has an extension that supports an exiflow workflow.
I'm constantly disgruntled by F-Spot, but I keep returning to it, because it keeps getting better. I'm not crazy about F-Spot for importing images off of my digital camera, so I'm thinking about switching the default to gThumb.
And now I've moved to Shotwell, because that's now the default in Ubuntu. I'm thinking about Lyn on my Mac.
Other tools of interest:
Services for scanning old photos:
Tags + types. Tags can have types. If I want to get really funky, types can have relationships -- an ontology! For example, the "Eugene Eric Kim" tag could be of type "People." This would allow me to do faceted classification.
Collections (or albums) cannot be tags, because you want to be able to do special things, like define cardinality and other metadata within a collection. However, you ought to be able to assign a photo to multiple collections.
Developing and Printing
Notes on using expired film. Quick summary:
- The freshness of the film depends on how it was stored (e.g. cool, dry temperatures are optimal)
- Some people advocate for stopping down the film one-stop per ten years, especially higher ISO (400+). Others suggest simply using the box ISO. Experiment to see!
