Macro Photography with the Raynox 150

I’ve had a chance to try the Raynox 150 recently on both my Pentax M200/4 and my Pentax M100/4 Dental Macro.

The Raynox 150 and 250 are the same optics as the Raynox DCR 1.5 and Raynox DCR 2.5 but come together in a kit with the 52mm mounting plate. These lenses are very well made and are achromatic to deliver nice sharp images without aberrations.

These test results aren’t scientific or even done in a controlled atmosphere. They are just images for you to look at and evaluate to see the quality these lenses can produce.

The Raynox 150 is approximately a 208mm focal length with a diopter strength of 4.8, the 250 is about 125mm and an 8 diopter. Most people choose the higher magnifications of the 250 or 2.5, however with larger magnifications than 1:1 the DOF becomes very thin and the working distance becomes very close. I chose the Raynox 150 mainly for my longer focal length lenses to maintain a greater working distance for more light control while shooting. I bought the kit as I will probably want the 250 for my mid range standard lenses and will post results with those soon.

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.

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.

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.

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:

Infrared Photography and Pentax F300/4.5

Added a couple of new lenses to the infrared photography lens hotspot database,
the Pentax F300/4.5 and the Pentax F 35-70/3.5-4.5.
