It seems that a lot of people have a hard time settling on a file structure to use for their digital photos. There are a number of different approaches, and the tools that you use will heavily influence this but I think it’s important to settle on something independent of your tools since those will change over time.

There are a couple of things you want to make sure to accomplish with the directory structure that you use for your photos.

1. Consistency is important. You want to make sure that regardless of camera, subject or any other variable there is a consistent way to find a photo.

2. Uniqueness of photo name is important. Even though the directory structure would allow for multiple files with the same name, you should guarantee that every file is unique and “fully qualified” for each individual photo.

3. Backup management is handled most simply through your file structure. I don’t like to rely on fancy backup programs to know what has been backed up or not, I like to be able to achieve this through chronology.

I’ve been using the following structure for over 5 years and I’ve found it to work very well. I’ve used it with a number of different photo management programs, including my current favorite, Adobe Lightroom. It is inherently driven off of the timestamp of the photos.

Let me highlight the five critical sections of this (cross-reference to numbers above, sorry Tufte).

1. Your photos live in a root directory. This could be anywhere and just identifies the home of all photos.

2. Start your directory structure with the year. There should be a year for every year you have photos. This cascades into months and finally days.

3. The “day directory” itself is typically auto-created by your importing software but it likely won’t have the a title for it (e.g. “Around House”). I add this myself, and I have an additional trick in that I don’t add that text until I’m done doing post-processing on those photos (purging, keywords, metadata, etc). The other reason to add a title is to give you some visibility on what you are looking at when you are just looking at your directory structure.

4. The filename itself is really simple. I always use YYYYMMDD (year, month, day), dash, HHMMSS (hour, minute, second), dash, and lastly the serial number of the photo from the camera. The serial number is important since you may take photos in burst mode and have more than one in a second. Or, if you are shooting with multiple people and multiple cameras, and happen to take a photo in the same second, you are still unique. I could put more here (camera serial number, ISO, etc. but I’ve never found it necessary). The completeness of the timestamp inside the filename is great. I can always figure out the full path to any file just using it’s filename.

5. The last “Other” is a catch all. Sometimes I get copies of photos that other people take. I don’t typically interleave these with my photos, and instead just drop them in the Other directory. This is a catch-all for such photos, sometimes even having directories inside other like “Bob’s Trip to Alaska”, that is all grouped together. The other directory is last which is helpful for backup.

The backup strategy for this structure is a simple top-down flow. I never backup a month until it’s completed. The great thing here is that once the time has passed, the directory and files in those directories are not changed so you don’t have to worry about going backwards in time. (Note, I also mirror files every night, and this is automated to other discs.)

Just bought greenrequest.com.

Got home after running (and walking) my first 5k in forever.

Wondering if anyone I know uses StumbleUpon? If you do, ping me.

Tammy and I had a really funny conversation today on the way home from the grocery store. I prompted the question of giving up the Internet for something. For example, if you were forced, would you give up chocolate, or the Internet. Forever. Not a month, but permanently. Would you never have another bite of chocolate so you could continue to bathe in the wonders of the Internet.

To me this question was simple – I’d be passing on the chocolate. I love chocolate. Don’t get me wrong. Lindt and Vosges are very special brands in my book. But compared to the Internet, it’s no question.

I theorized that if given the choice of continuing to use the Internet or drinking nutrient complete meal replacement shakes that I would have to think for a long time. What flavors exactly? Tammy laughed at me, citing that I wouldn’t make it through a single Thanksgiving.

So, that made me wonder, what would your breaking point be? What food do you care so much about that you would abandon the Internet forever for it?

A few weeks ago I was flipping through a recent issue of Home Power magazine and I stumbled upon an article abut solar tubes. (Sorry, I would provide a link to the article but they don’t make it available online.) Solar tubes are not new technology, but there has been some pretty amazing improvements in recent years. The author of the article had installed a Solatube in his office and was very pleased with it.

Shortly after this we ran into Solar Midwest while we were at the Living Green Expo. They had the Solatube units on display and I got to ask a ton of questions. Shortly after that I got a quote and decided to get one installed.

The basic principle of the Solatube is exremely simple. You mount a light collector on your roof. You then run a 10" or 14" tube that is exceptionally reflective to a room in your house. There are three main areas of technical focus. Making the collector dome as efficient as possible, losing as little light as possible in the tube, and distributing in the room in an even way. This diagram from Solatube’s website sums it up well.

The advancements in the collector dome and the efficiency of the pipe are incredible. It can collect light all day, picking up even dull light on a cloudy day. There is no need for direct sunlight. The tube itself is extremely efficient and loses very little light.

Let me skip to the after shot. Here is the room with the Solatube.

The effect is shocking. This room was one of the more poorly lit areas in our upstairs, and now it is as bright and enjoyable as the most windowed areas in the house. Note the relative sizing of the Solatube versus the cans next to it. This is the 14" unit and it delivers a whopping amount of light. Tammy and I are both very pleased with it and are thinking we will likely have two more installed at some point in the future.

Some FAQ items to share with everyone, in no particular order:

Does heat transfer through it?

Surprisingly no. The Solatube itself is just sending the light. The heat part doesn’t make it down.

What about storms?

I felt the dome, and it’s impressively thick. I’m not sure exactly what would take it out, but I’m very confident the roof around it would have issues before the dome itself cracked.

Is it ugly?

It’s another thing on your roof, so you may not like that. We were able to install it in a location that is completely invisible.

Due to this great placement you cannot even see the dome from the street. I don’t think it would be an issue even if you could see it.

Does it save energy?

Well, it depends. If you have rooms that you use lights during the day it definitely would. Our situation was more of a luxury since we like a lot of light and this room was just dimly lit. We didn’t use lights there that much during the day, but it was drab. Now it’s bright and full of light.

Great locations for this technology would be a windowless bathroom, or a closet. Those are the locations we are considering for a future use. Or frankly anywhere you want nice, full-spectrum sunlight.

Would you recomment Solar Midwest?

Yes, they did a great job through the whole project. As a bonus, all the pre-sales activity was via email which I appreciated.

What about basements?

To me the killer utility of solar tubes is in the basement of a house. This is easily done in a new build, but nearly impossible in an existing house due to the tubing required. I can only dream of the day when I pipe a bunch of natural light into the lower level of a new house.

Can you see moonlight?

Yes. There is a cool bluish glow on a full moon.
