UltraViolet Photography with Hoya U340

Been working in UltraViolet photography with the Hoya U340 and an S8612 filter stack testing to see how low my two “accidental” UV sensitive lenses might go.

The Steinheil is rated to 320nm and previous test I’d done with the Lensbaby Soft Focus Optic showed it performed well with the U360, so decided to see how the Soft Focus Optic did at 340nm.

Both were shot at f5.6 as I’m finding UV needs allot of light. Does allow for limited depth of field though. A modified Yongnuo 560IV flash was used to produce the lighting.

The Stienheil does produce a well defined focus and the Lensbaby lives up to its traits of very nice soft focus effects.

Bodie State Park in Infrared

It’s been a couple months since I’ve taken the time to photograph, so decided to do my usual spring adventure to Bodie State Park and try some infrared photography with the Lensbaby Twist 60.

Made the trip simple, using one lens and one filter. Though I usually prefer the effects of the Tiffen 87, this time I decided to use the Hoya R72 so I would have some images to convert to faux color. The images I didn’t convert I left in the normal blue/red this filter produces rather than converting to monochrome.

Pinhole Ultraviolet Transmission Lens Test

Learning Ultraviolet Photography is proving to be such a challenge it reminds me of when I first picked up a camera. How wonderful to be able to shoot 35 photos and not find a single keeper. Reminds me of the film days. I’m finding that trying to imagine how an image will appear, when the focus is using non visible light, has many variables that can affect the outcome.

One of course is the light source. If you don’t have full sun cover, using a dedicated light for a specific bandwidth or a full spectrum flash is essential. Next is choosing quality filters that absorb all light not wanted to affect the image. Also, I’m finding that the lens choice is just as important as the light source itself. Very few lenses are truly dedicated UV lenses made from quartz rather than glass, so the challenge is finding “accidental” lenses that permit good UV transmission.

Below is a basic test I used to determine which of my older lenses would permit the best UV transmission in the 360-365nm bandwidth. I used a pinhole cover with a dedicated Hoya U360 and BG40 filter stack to eliminate all light in the visible and IR range. I used a white plastic as the background and focused a dedicated 365nm light on it. White balance was done on the background. Exposure time was 15 sec and iso 1600. All phtos were post processed with the same settings.

All lenses tested were set to f4 and the rear of the lens was set at 2 1/2 inches from the background. Lenses tested were the Lensbaby Sweet 35 and Edge 80 optics, the Lensbaby Twist 60 and Selective Focus optics, an El-Nikkor 50/4 and Meyer Optik Domiplan 50/2.8 and Helios 44M 58/2. The Domiplan is supposed to transmit down to 345nm from other test located on ultravioletphotography.com (great reference site). The El-Nikkor is also supposed to be a good transmitter. The clearer the light through the lens itself signifies better UV transmission, purple signifies the worst.

From my basic, non-scientific test I was suprised to see the Lensbaby Soft Focus optic seems to perform as well as the Domiplan and both the Lensbaby and Zeniton 35mm lenses performed well. The Zeniton 135 performed poorly, even though it is the same optical construction (4 element / 4 groups) as the Zeniton 35.

Test are as follows:

UltraViolet Photography and Lensbaby

UltraViolet Photography and Lensbaby

Recently I have begun trying to work with UltraViolet light and my full spectrum K1. I’m enjoying it very much as the learning curve is proving to be a real challenge.

Most of my older lenses (and non of my newer digital) transmit the UV spectrum very well but I’ve been lucky enough to come across a few that are permitting me to do a some hand held shots. I’m finding simpler lenses with fewer elements and cemented groups seem to be working best so far. I’ve picked up a few 4/4 Zenitons and hope to show the results later in the spring during the wildflower season.

Here are a few using an older Lensbaby Soft Focus optic. It is 2 elements in 1 group.

The following are the exposure settings, filters and light source I used while photographing a White Geranium.

All were shot at f5.6 and on a 25mm tube.

Lensbaby Twist 60 Optic

Last month I purchased the Lensbaby Twist 60 Optic.

It is based on the Petzval design and is supposed to produce a swirl of bokeh, much like the older Helios lenses. I had been curious about it since it was released but also very hesitant as most of the uses seemed to be focused around portraiture photography. As I rarely shoot pictures of people, I wondered how this style of lens effect would work with inanimate objects also.

At wide open f2.5 & f2.8 the swirl effect of the Twist 60 optic is very pronounced.

It does mild down significantly by f4 – f5.6 and is almost non existent by f8 producing a normal view from any standard lens. I found the wide open swirl effect to be a little distracting but really do like how a minute amount of swirl from the f4 – f5.6 range does make the subject stand out a bit more.

Where this optic really shines for me is mounted on a 25mm extension tube, bringing it up to almost a 1:2.4 magnification macro.

I did try it on a 44mm tube but didn’t like the effect as much as the 1:2 ratio.

Though I occasionally find a use for the Sweet Spot or Slice Focus of my other Lensbaby optics, my favorite optics so far have been the Zoneplate and Plastic. I’m quickly seeing the Lensbaby Twist 60 optic will join those two.

Something about the “so called” imperfections of early film photography appeals to me.

 

Seeing in Black & White – Infrared Photography

Infrared Photography resembles the image in my mind’s eye.

I always preferred shooting black and white film before I moved to digital, I even usually prefer seeing other art formats in B&W. I didn’t even make the jump to digital until around 2007/08 because of the desire to continue working with b&w film and prints in the darkroom. The primary reasons for the switch were the hassle of disposing of chemicals in a rural environment and the Polaroid effect of seeing instant results.

I loved the manipulation process in the darkroom to create the image I liked, I can’t say I really enjoy doing the same on a computer.

Over these digital years I have attended some fantastic workshops on how to process digital black and white, much the same as one would create a b&w image from a color negative. One of he best was at Shooting the West with Mark Citret, learning how to adjust curves, contrast and hue/saturation to try and achieve detail in each zone of grey from white to black.

Still often I would find myself shooting in color. If the zones of grey were off a bit or the detail wasn’t fine enough in a particular zone, color would often mask what my mind’s eye thought should be there.

This last year I decided to try infrared photography again and had a Pentax K-01 converted to full spectrum using r72 and #87 filters on the lens.

What a joy! To work in almost pure black and white again has been extremely satisfying.

I’ve realized that even though my eyes do see color, (I can distinguish red from blue and yellow or green, etc.,) they are always bland.

In my mind’s eye I see in light or lack of, resulting in shape, form and texture.

Lensbaby Plastic Optic Revisited

Very busy this month but I was able to revisit the Lensbaby Plastic Optic and play with a bit of Macro Photography in the yard.

Recently picked up the Lensbaby Plastic Optic.

I arrived at Lensbaby to late to buy the original optics as a kit and started with the Sweet35.

Though the Lensbaby system isn’t for everyday shooting, I really enjoy the special effects they create.
Think I own all of the original optics now plus the Sweet35 & Edge80.

Of all of the first generation plug ins, I think the Zoneplate and the Plastic are my two favorites. Really enjoy the vintage Holga or Dinah look this optic creates.

Lensbaby + Pentax K-1

Playing with the Lensbaby on the Pentax K-1.

Been busy with work and dealing with the cold weather so haven’t been able to do much in photography this month.

I did get enough time to take the older Lensbaby optics out and play with them a bit on the Pentax k-1.

Very different using the double glass and single glass instead of the newer Edge or Sweet models but found them very enjoyable to work with. Fun to have to think about the aperture one wants first and then install the disk as opposed to setting the aperture in the lens.

I did get lucky one day and had an Egret land in the artisian well I was working around using the double glass.
