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.

Steinheil Cassarit and Ultraviolet Photography

I’m finding ultraviolet photography to be one of the biggest challenges I’ve come across in the photographic process in years. Such a huge learning curve.

Due to the short bandwidth of ultraviolet light, the reflective transmittance doesn’t seem to travel as far as visible light, plus this also causes a focus shift issue as photographing in infrared does.

With the sensitivity of the converted camera, I have been able to pick up the ultraviolet spectrum at a decent iso (around 800 – 1600 as opposed to 200 – 400) and live view permits achieving a fine focus if I take the time to really review and adjust before I shoot.

More of the problem seems to be in the lenses. Glass, air space and the cement used to join elements in a lens all interfere with the UV transmission. True UV transmission lenses (made with quartz-fluorite elements instead of glass) are still manufactured and a few older ones can be found second hand but these are way beyond my price range at an approximate cost of $3000US and up.

Fortunately ultravioletphotgraphy.com has a list of true and “accidental” lenses for ultraviolet photography work. I managed to pick up one of the Steinheil 50mm Cassarits recently and imediately noticed a difference. While not a spectacular shot, it is the first time I’ve been able to achieve focus on any subject farther away than about six inches.

This was shot midday 1/4 second, f8, iso 1600 using a Hoya U360 and S8612 bringing it to around a 360-365nm light source. The Steinheil triplets have been tested to have a cutoff of around 320nm. I am looking forward to testing this lens (as well as an older Cassarit 100mm) with a Hoya U340 to see if I can achieve a deeper UV cutoff point.

Experimenting with the Nik Collection Software & Silver Efex Pro

I’ve been reading a lot lately about Monochrome converted DSLR’s and since I love photographing in B/W, the thought of purchasing a used camera for conversion has been teasing my mind. Since I already have a higher end DSLR that produces excellent monochrome when processed in Lightroom and Photoshop, not to mention a full spectrum converted Mirror-less for monochrome infrared photography, I am struggling with the thought of paying out a few thousand dollors for another camera.
Though I know I would love to shoot in Black and White again, just like the film days, I decided to try the next best thing – software that emulates film. Nik Collection Silver Efex Pro.

Other than the vocabulary, I find working in Silver Efex Pro to be very intuitive much like working in the darkroom. I don’t really care for the preset effects but find the selection of film styles to be very similar to what I had worked with pre-digital. Everything from various Agfa to Kodak films. When I shot film I usually preferred the Ilford Delta series but found I do like the TMAX and Tri-X emulation this software provides. One can set the film style of choice, adjust grain and then proceed with normal darkroom techniques.

The selective point allows adjusting brightness, contrast and detail to a given area. This is where I wish it actually used the vocabulary of dodge and burn but the results are similar. One can also do these adjustments to the image as a whole as well as fine tune highlight and shadow while bringing in detail (structure in the vocabulary.)

What I enjoyed most was the loupe view which has the zone system overlaid so one can see how much of the photo falls into each zone from no detail white to pure black.

And to top it off there is a finalization series to bring the image to full print characteristics. Everything from tones, edge burns, and even custom negative carrier edges.

Here is a before and after, the original was shot on a converted camera with an 850IR filter. The second is the same photo run through Silver Efex Pro. Click to enlarge for viewing differences.

I was originally only interested in the Silver Efex but it comes as part of a complete download in the Nik Collection. I couldn’t help put experiment with the Analog Efex while I was at it. Great fun for creating that 60’s snapshot effect. Another before and after, bland photo turned into vintage.

Best part is Google is offering this software for free now and it plugs right into PS as a filter. It just might curb my desire for that monochrome DSLR.

Infrared Filter Comparison

I’ve really been enjoying working in digital IR this last year and have been doing a few Infrared Filter Comparisons to see which effect I prefer the most. I have attached a test subject of a tree stump in the desert shot with R72, #87 & IR850(87c) at the end for comparison. Continue reading

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.

Tiffen 87 IR Filter

Testing the Tiffen #87

Recently I picked up a NIB Tiffen #87 Infrared filter to see if I would enjoy working more with the shorter IR wavelengths (to produce a truer Black and White image) or if I wanted to stay with the 720 and under filters to achieve some color from visible light.
I have always preferred viewing B&W photos and movies to color and when I hold an image in my mind it is almost always in B&W.Infrared Photography, Infra Red, IR Photography, monochrome, monochrome photography, Pentax K-01, Tiffen #87 Filter, Mono Lake CA, Owns Valley CA, Lee Vining CA
The 87 comes in around 795 or just at the baseline of the IR spectrum. Not quite as black as the 093 (830) or 87c (850) but still dark to the human eye.Infrared Photography, Infra Red, IR Photography, monochrome, monochrome photography, Pentax K-01, Tiffen #87 Filter, Mono Lake CA, Owns Valley CA, Lee Vining CA
I do like the contrasty effect the monochrome images have over the false color, though it is difficult to achieve focus.

The majority of my favorite lenses are still manual focus, so I will just have to practice more.
If you can find this filter it is made of glass with a metal ring and well constructed, plus it comes in at about 1/2 the price of other name brands.
I find the images comparable to the Lee 87 film filters for those who already have a holder system.

I did notice under the right light and white balance there were a few shots that did have a hint of blue sky after an attempt at color swapping.

 

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.

Very pleased with he results and really like the soft focus effect the lensbaby plastic optic offers.

And a few with IR:

Lensbaby Plastic Optic

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.

Infrared Photography

I remember trying Infrared Photography a few times in my film days and found it difficult and challenging.

It always seemed I was guessing the exposure time and the focus, trying to approximate the red line on the lens distance scale.

Winter Farm IR

Recently, I acquired a Pentax K-01 and had it converted to a full spectrum camera. Unlike film, digital sensors are sensitive to all light waves (UV, visible bands and IR) so most cameras use a hot-mirror to block the infrared bands and pass only visible light.

Winter Mules IR 1

Most conversions replace this hot-mirror and replace it with an IR based filter for a full time conversion, usually in the 720nm range. With the full spectrum conversion the mirror is removed and the IR filter is placed over the lens, much like the film days; however, unlike the film days I can see the image in live view just as if I was looking through a viewfinder.

Winter Mules IR 2

Apparently the new mirror-less systems make fantastic digital infrared cameras. They automatically set accurate exposure and the focus can be determined manually via live view or calibrated for auto focus. Another wonderful aspect of the K-01 is that it will take all my older Pentax K mount lenses.

Winter Tree IR

I now need to experiment with several to determine which will be good performers or or which will be susceptible to flares and hotspots. Infrared is often most noted for its use with contrast or faux colors with vegetation.

Here are a few shots from the winter local scenery, a bit different but fun. I look forward to working with the camera as the spring green comes around.

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.

National Automobile Museum – Reno

Every time I visit, I feel one of the most overlooked attractions, in Reno Nevada is the National Automobile Museum.

This place is amazing. It contains vintage automobiles in pristine and restored condition from the Harrah’s collection.

Era’s start with the early horseless carriages and vehicles built for commercial and race uses to the mid 1960’s. The history behind many of these vehicle is fascinating in itself but the architecture and art in their designs is beautiful.
