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.
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.
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.
kolarivision.com has an excellent ir lens hotspot database already compiled; however, I noticed most of my older film lenses weren’t included so decided to create a database (bottom of page) testing these lenses on the Pentax K-01.
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.
Lately I’ve been examining the color cast created by the ND filters I own.
I have a beautiful Singh-Ray soft grad 0.9 that was given to me as a gift years ago and a set of Formatt Hitech 0.6, 0.9 and 1.2 which I use primarily for strobe work.
Granted the Formatt’s are resin CR-39 instead of glass but they permit me to open my aperture for shallow DOF with the slow flash sync speed of the Pentax.
I have notice a small amount of magenta color cast while using them as such but never found it to be too overwhelming to clean out in post.

On a shoot a couple of months back I tried to stack the Formatts to achieve a 7 stop ND effect.
Wow, was the color cast dense. So heavy I couldn’t pinpoint a spot with either LR or PS Raw to achieve a natural WB.
Looking on the web for ND color cast I came across a review for the Ice ND1000 by a fellow Pentaxian which showed minimal casting between the image shot and corrected.
When B&H listed the P series of $49.95, I decided to give it a try. If I didn’t like it I wouldn’t be out that much.
While I haven’t used it much, I’ve been pleased with the results so far. It is made of optical glass and feels much like my Singh-Ray in build quality, one to take care of for long life
Ice ND1000 + 1.3 stop circular polarizer
Spectator during the shoot 1.3 stop circular polarizer
Decided to try an experiment to see how my filters compared to each other for cast by brand.
I kept as many constants as possible: tripod, f8.0, ISO 100, 50mm focal length and WB set in camera to 5500k.
In LR the as shot WB showed as 5300 temp and -16 tint (slightly to the green) on all photos.
I chose the exact same point (mid grey rock) in each photo to achieve the WB correction and will list the difference with each photo. Continue reading →
Often when I’m researching historic cemeteries to photograph I turn to a website named “findagrave.com.”
Recently, out of curiosity I decided to look up the graves of my grandparents on this site to see if and how they were listed.
Thankfully, someone had recorded a memorial within the site and a photographer had added pictures of the gravestones.
To my surprise there were no links from one family member to another, parents, spouse, siblings.
The natural progression for me was to then add these family connections then locate and upload a photograph of each individual. Continue reading →
I’ve realized it has been over 15 years since I’ve worked on any form of motion/action photography.
With either night skies & light painting or my primary focus of historic artifacts and locations,
most of my subject matter has been very still. Depth of Field and composition had become my central focus and half my work involved tripod use for longer exposures.
This year I’ve been feeling the need to bring my photography back to me, inspire my feelings of creativity and learning.
I’ve gone back to many of the older techniques I learned in my film days, selective focus, soft focus, black & white (which has always been my preferred taste),
pinholes and zone-plates; I’ve even been trying to refine my use of strobes.
It has been difficult to find motion inspirational. I enjoy wind and water working a landscape but receive much more pleasure from simply watching.
The same applies to wildlife. And though I do enjoy partaking in certain sports, I find spectating is usually quite boring.
Reflecting back on my childhood, the two sports I always enjoyed watching were baseball and rodeo.
Besides requiring incredible athletic ability and endurance, I find rodeo fascinating because of the teamwork.
Especially when your partner, as well as the opponent, doesn’t reason with the human mentality.
Being able to communicate with your horse to make the tight turn of a barrel or cut a steer for roping takes talent.
Riding the bulls is one of the finest shows of endurance, agility and reading your opponent.
I first remember hearing “Thinking in Color” in a workshop I attended at SHOOTING THE WEST a few years back.
Stacy Pearsall mentioned to “think in color”, pointing out how certain colors compliment the color of the primary subject and to use them when framing your background. Mood and visual relationship of the photo can be portraited by varing the color relationships including shadow to highlights, blacks to white.
Last month I read another interesting article by Moose Peterson on Sam Mallery’s B&H Photo Insights Blog mentioning “Color Concious”. Continue reading →
