I have scored a few product shoots because of my demonstrated ability to take good pictures of glass objects. Truth be told however, there really isn’t a whole lot to it.

First step is to have the proper environment to shoot in. For me that means using my oversized DIY PVC Light Tent. It is big enough that the light is distributed really well within. For added measure, when I was building it and then making the second revision, I made sure that the fabric would cover any of the PVC so it would not show up as a reflection in the objects I was shooting.

Second step is, obviously, lighting it. When shooting in the big tent, I tend to go between two different placements for my lights. I use a pair of 27W, 5500K compact fluorescents in standard 10″ clamp light fixtures I got at Home Depot. Sometimes I will place them slightly ahead of center on either side of the tent. Other times I will put them overhead, either facing directly into the tent or bouncing the light off the rafters overhead (sounds goofy, but it works). I take a couple of shots, see how they look, and then readjust as necessary. Most of the time I can get a good idea of how the lights are working from peeking through the viewfinder and then adjusting.

I generally do one or two shots in auto mode to get some idea of the f-stop and exposure ratio, then start working from there. As you can see from the EXIF for the shot above, it can be fairly fast. But again, that depends on how you light it.

One key I have been working on is how to keep the camera reflection from appearing in the object. I account for this in a couple of ways:
1) The opening in my front curtain is only large enough to let the lens through.
2) I do not use any sort of lens hood.
3) When practical, I elevate above the object and shoot downward at an angle. Straight on shots are the worst for showing the camera lens, and I try to avoid this at all costs.
4) When 4 isn’t practical, I try to get any opaque objects on the surface of the object to be in the forefront.
5) When 3 and 4 don’t work, I just deal with the fact that the reflection is part of the image.

These things must be working, as I continue to get product shot engagements, and several specifically indicate it is because of my work with highly reflective surfaces.

I had an occasion where I needed to light an object from underneath (the glass of beer in the pic above). I wrestled with it for some time, and then came up with what turned out to be a pretty easy solution.

Using a flat fluorescent light fixture I picked up at Home Depot, and a piece of black craft foam, and my large DIY light tent with glass riser, I was able to get the photo above. I cut a hole in the black craft foam that was roughly the same size as the base of the glass. I then put my black backdrop into the light tent, set the fluorescent light on my workbench inside the light tent, and then placed the craft foam on top of that so no light escaped except through the hole I had created. From there I inserted my glass sheet to have a riser (which was conveniently about an inch higher than the surface of the fluorescent light), filled the drinking glass with beer, and turned on the light. This photo did not require any additional lighting other than the fluorescent underneath the product. And by using the pane of glass as a riser, a nice reflection appeared as well.

That’s all there is to it, hope it works for you if you need some illumination from underneath on an object.

As you may have gathered, I have been taking pictures of some local glassblowers and the work they produce. I have also been trying to take pics of the guys in action, but I was missing one key piece of equipment - a proper lens filter.

The glass that these guys use for their artistic glasswork is called borosilicate. When it is introduced into the flame, you get a very long sodium flare, as illustrated by the photo at left. The best way to counter this effect is to employ a Didymium filter. The glassworkers have eyewear made from it, and you can order large square pieces of it to use as a type of shield for a glassworking station. But you cannot easily find a camera filter made from this stuff. So I contacted the company that the glassworkers get their eyewear from. Turns out that Aura Lens, based in Minnesota, can take a normal UV filter, remove the filter element, and replace it with Didymium treated glass. Mine arrived last week (cost was roughly $70).

Friday I went to the glassworkers studio and took about 150 shots. The picture at the top of this article was shot through the Didymium filter. Compare that to the unfiltered shot further down and you can really see the difference.

Lighting these situations can be pretty tricky, depending on what you want to show. For a few of the pics, I wanted to be sure I got the workers hands in the image, or part of their workspace. To accomplish this, I placed my homemade softbox on my Olympus FL-36 flash, mounted on my Gorillapod and fired with the Cactus remote triggers. I moved it around a bit during the shoot, and was pleased with the results.

I love the doors that photography and website management and consulting have opened for me. I have been able to travel to some interesting places (Detroit Auto Show, Toronto) and also meet interesting people and learn about new things (the glassblowing, a recent photo shoot about wine). I am especially pleased to be involved in the main project these glassblowers are working on - The Community Carbon Project. Cool glassware that is recycled and useful. Can’t beat that.

For my PVC Light Tent, I was originally using posterboard for a backdrop and some old white sheets for the “curtains”. Last week I went to a local fabric shop (Denver Fabrics, not the same as the Denver Fabrics online - long story) looking for some white ripstop nylon or sport nylon, along with black and white muslin. All they had was the white muslin. So I looked around the store a bit, and found some black poly poplin suitable for a backdrop. And then I found some cotton with a polyurethane laminate that is intended for people making their own baby diapers. It seemed suitable to me, so I got enough of it to make side and top curtains for the tent. I also got some velcro to use as attachment points.

Once home, I placed velcro squares along the top left and right PVC pipes to hold the side curtains up. I allowed for a little bit of crossover to the lateral pipes, in order to make sure the vertical PVC was not visible in any reflections. I had already had the cotton laminate cut to the rough dimensions I needed, so I hung one corner up, attached velcro in the remaining appropriate places, and trimmed the excess off the bottom. Did the same on the other side, then the top and was all done with the curtains. Had enough excess that I should be able to use the material in a larger softbox I am planning to build.

After this I mounted additional velcro to hold the backdrops up, and applied velcro to the backdrop material (the black poplin and white muslin). After a few test shots, I decided to add the front curtain, and cut a large + in the front curtain to put my lens through. All in all, things have worked pretty well in there. Here is a sample photo.

I still need to work out lighting and white balance, but with a little bit of time, those should work out pretty easily. More difficult is going to be perfecting the underlighting of objects to really give them some pop. I will be experimenting with that this week.

Oh, some people have been asking about these beer bottle glasses I am taking photos of. They will be on sale soon, and I’ll be sure to post a link when they are. Cheers.

Besides being a photographer, I am also a website developer and consultant here in Colorado. It is a lot of fun for me when I get a project where I can use my skills from both areas. Such is the case this week, where I am working on a couple of websites for a Boulder glassblower. My existing light tent was not adequate for this project (no underlighting), so I set out to build a new one out of PVC. This isn’t rocket science, and a lot of people have done it, but I needed mine to be just a little bit different. I decided I was going to shoot the glass items on top of a glass riser, with a fluorescent light fixture underneath. To that end, I set of for Home Depot.

Shopping list:
- 8 1/2″ PVC Side Outlet 90’s
- 4 1/2″ PVC T’s
- 8 1/2″ PVC Male Threaded - Slip adapters
- 4 10′ x 1/2″ PVC Pipe
- 1 Low profile fluorescent light fixture
- 6′ 14/3, rubber coated extension cord (just cord, no ends)
- 15A Outlet Plug
- 1 18″x36″x3/16″ plate glass

Why I bought some of this stuff:
- The threaded male / slip adapters were because the side outlet 90’s have one outlet that is threaded. Instead of spending the time with a Dremel removing the threads, I just spent a few cents on the adapter and called it done.
- Fluorescent fixture and associated cord, plug was purchased because the selection of plugin light fixtures was not adequate for my needs. Total cost for the fixture, cord and plug was around $35, IIRC. If you are not comfortable with wiring together electrical devices, you should look for a pre-wired fixture suitable for your needs.

Construction was pretty simple.
1. Measure 14 sections of 30″ each (or whatever length you want to use) on the PVC pipe. After cutting, I used a file to clean up the edges.

2. From the remaining length of pipe, cut 4 pieces 3″ long. These are the risers to go higher than the light fixture (depending on your fixture, you may need to go higher than 3″).

3. Put together the 90° outs and the slip/ threaded adapters.

4. Using a rubber mallet, put one piece of pipe into one end of a 90° out. Continue doing this, making a square base such that the threaded/ slip adapters are facing upward.

5. Insert the 3″ lengths of pipe into the threaded/ slip adapters.

6. Attach 2 PVC T’s to a piece of pipe, and then set the completed piece on top of the 3″ lengths on the base. Do this twice.

7. To the top of each T, insert a 30″ piece of pipe.

8. Same as step 4, construct a square frame from the remaining 4 pieces of 30″ pipe and the 90° outs (with the threaded/ slip adapters facing up).

9. Invert the completed square frame from step 8 and attach to the top of the frame from step 7.

10. Completed item should look similar to the photo above.

11. For good measure, I took a wet paper towel and wiped down all of the pipe.

That is all there is to it. You will of course need sheets or fabric to make the shell of the tent, and some kind of material for the backdrop. So far I used 3 single-size sheets to cover my tent, a piece of posterboard for the backdrop, and my clamp lights for lighting (I have 3 of those).

My immediate plan is to hit a fabric shop and get white and black muslin for the backdrop, and also get enough white fabric to make a proper slip cover for the tent. But for now this setup is working well. Here is a photo from the tent.

This tent is pretty big and portable. If it is too big for your needs, you could try this alternative design. I just might have to build one of these and try it out too.

I have had my Olympus E-510 for over a year now, and I can say it has served me well. From time to time people ask me why I chose to go with Olympus for my DSLR purchase. There were a couple of factors at work. The kit I purchased (E-510 with two lenses) was very competitively priced compared to what Canon and Nikon had to offer. To get comparable equipment from the other two would have cost me a few hundred dollars more. Sensor resolution (10MP) was the same as the other two manufacturers. And then there was the big deciding factor - image stabilization. Olympus was the first with IS for their DSLR cameras. You had to buy the 510 to get it, but it was there. Even better, it is in-camera. That means the lenses don’t cost extra if you want IS (or VR) in them. That really helped frame my opinion up front. But this wasn’t (to me) a small purchase.

Wolf Camera, in conjunction with Olympus, had a special deal going where you could “borrow” a camera (E-400 or E-510) for a weekend to take some pictures and see what you thought. I jumped at that chance. Unfortunately, by the time I got there, they were out of the 510s. I took the 400 home for the weekend and really enjoyed shooting with it. I must admit, I was intimidated by making the jump from my P&S (Canon Powershot G5) to a full on DSLR. But I had a good weekend of shooting, and decided what the heck.

I then started doing my research online. I found the 510 for an even better price from B&H Photo/ Video. Fortunately for me, the manager at Wolf decided to match the prices I found at B&H when I was ready to walk out the door. That willingness to eat the margin a bit also meant I will buy from them in the future - mostly prints and stuff I think.

Now that I have had this camera for roughly a year, I naturally have my list of likes and dislikes about it.

Likes:
- Lightweight (in my camera/ laptop backpack, this hardly adds any weight)
- Great image quality (never had an issue with the image quality)
- Sensor cleaning (the sensor cleaning system seems to work well, don’t see any problems in my images)
- Kit lenses are good quality (I wouldn’t know what ‘great’ glass is, but these do everything I ask)
- Live view (even if I never use it)

Dislikes:
- Limited EV bracketing (3 shots, in one stop increments)
- Unique Olympus USB connector (cables are more expensive and harder to find)
- No tilt/ swivel LCD (was useful on my G5)
- Requirement of Oly xD card for pano mode (I can take panos manually and stitch in something else though)
- “Live capture” software has additional $$ cost
- FL-36 (seriously, why did they even build/ sell this?)

All in all, I can’t say I made a very poor decision in buying this Olympus. It continues to serve me well. That said, Olympus as a whole doesn’t seem to be very innovative at the moment. This worries me. I don’t have a huge investment in Olympus glass and gear, but it would be nice if they had an upgrade path that looked enticing. Compared to what I am seeing from Canon and Nikon, Olympus has a lot of catch up to do. I am not ready to upgrade just yet, so this isn’t of immediate concern. Who knows, maybe they do have something impressive in the works. They need to. The E-3 is outdated now, and the E-30 is not even close to being an evolution.

At first glance, you immediately wonder “How did they do that?”. This question is either immediately preceded or followed by “Wow, that is pretty cool.” I didn’t take the photo, but I think I have it figured out.
