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.
HDR – I Still Love It
I started shooting High Dynamic Range (commonly known as HDR) images roughly 2 years ago. I don’t shoot many (26 in my flickr gallery), but I enjoy shooting them. The gondola rail car in the photo above is the best one I have shot I think. Shooting HDR takes patience, at least with older dSLR’s like my Olympus E-510. Newer camera models, mainly ones that have arrived in the last 6-12 months, might have enough exposure bracketing built in to them to accomplish HDR captures with one click of the shutter release. Still others might have had a firmware update to accomplish this. It is my biggest hope that whatever Olympus brings out to replace the E-3 will have this feature.
I could write a tutorial on taking HDR images, but really, it would pale in comparison to the master, so I’ll let you have a look at Trey Ratcliff’s HDR Tutorial instead. I would also encourage you to check out his new book – “A World in HDR
“.
After the captures, you need software. I have been using Photomatix HDR since I started doing HDR images, and highly recommend it. Trey does too, and he has even worked out a 15% discount with Photomatix (follow the link to see how to get it). Once again, Trey tells us the best way to use the software. For me personally, I usually play with a couple different settings in Photomatix to get the photo looking just the way I want to. For the gondola above, I think there were 4 versions, this one being the best (in my eyes). I would encourage you to experiment as well, and get the look that pleases you the most.
If you are looking for inspiration in other people’s HDR work, or if you have your own portfolio of images to show people, you need to take a look at hdrspotting.com. This collection of images is extraordinary, and I hope I produce something worthy of inclusion. To become a contributor, you need to obtain an invitation code. While it is not clear to me how people get codes to give away, if you watch #hdrspotting on Twitter or ask around in the HDR group on Facebook, you should see a code pop up. I will post them to my Twitter feed if they ever come my way.
If you are a flickr user, you should look into the HDR and Photomatix groups. Great pictures and discussions happen in both.
Get out and try your hand at HDR, and put links to your pictures in the comments below. I love seeing what other people do with this new type of imagery.
