One of the more technical things one can do to their digital camera is modify it to either expand or limit the wavelength that is recorded.  Although this can be a do-it-yourself project, there are companies that will do this and guarantee their work.

Modifications can be for ultra violet, infra red, or astrophotography.   Here, for example, is a movie that William Castleman made with his camera.   You can read how he made it on his website.  Basically, he used his Canon EOS-5D (AA screen modified to record hydrogen alpha at 656 nm) to record this and then assembled it in Quicktime Pro (available for either Apple or Windows computers).  Editing/assembly was with Sony Vegas Movie Studio 9.  Incredible work!

There is much published online regarding Infrared (IR) photography.  Photo Extremist has a well written article on The Complete Color Infrared (IR) Tutorial Guide Walkthrough‘.  You can see a variety of both color and black & white work there – including this photo:

Gold is the Sky

Much more common is the alteration of the digital camera for Infrared work.  LifePixel receives great reviews for a variety of conversions (as well as repair of scratched sensors!).  They have excellent discussions and photographs from their work on Flickr in the group ‘Converted Digital Infrared Cameras‘.  Other conversion locations include Spencer’s Camera & Conversion.   Conversion for a Nikon Digital SLR could run you $325 to $375.    Also, Spencer’s has cameras for sell that are already converted.  A Nikon D70, body only, with full conversion runs $600.  However, it does open another world of photography!  Check out these Flickr groups:  Digital Infrared and D300 Infrared.

For the more ‘technical reader’, Luminous Landscape has posted an in depth discussion here {although the work on that site was done with a modified Cannon D20}.  Luminous Landscape, by the way, is a great source of photography information.

One might ask, “Does this ‘artform’ make be a better photograher?”.  Not necessarily.  I would argue that someone who takes poor ‘regular’ photos, will take poor IR photos!  However, Alexandra Morrison, the Canadian Photographic ‘Artist of the Year 2009’, says it does!  I invite you to see her blog, and specifically her article titled ‘Dedicated Infrared Digital Camera Conversions: Why it makes you a better Photographer‘.

For me, I love photographic experimentation and intend to try it!

The Early Years

I began my photographic experience with a Argus C-3. This was a range-finder camera and took great pictures!
In 1969 I purchased my first Single Lens Reflex (SLR) camera, a Pentax H1A. That camera served me very well as I experimented with darkroom techniques, traveled throughout Europe, and began producing photographic art.

In 1975, I traded my Pentax (and all of my lenses) in for an Olympus OM-1. I added a second camera body and then a third body, the Olympus OM-2. The Olympus system was simply wonderful! I carried the Olympus to several countries and then moved to Guam.

Moving to Nikon

A very good friend on Guam introduced me to his Nikon system. Before I knew it, I was the proud owner of a Nikon 8008 and several Nikon lenses.
As digital photography improved, and passed the 6 megapixel limit, digital photographs were finally to the quality of 35mm film cameras. I had already begun to have my negatives scanned and was using Photoshop to prepare my photos for printing and presentation. So, in 2004, I moved to the Nikon D70. The D70 boasted a 6.1 megapixel sensor. It provided excellent photographs — and was compatible with my Nikon lenses!

My Equipment Today

Finally, I ordered a Nikon D300 in July 2007. I was one of the first to order and had to wait until Thanksgiving, 2007 to receive it!
Technically, the D300 is incredible — as for quality of photographs, it’s difficult to beat! It offers the photographer a 12.3 megapixel DX-format CMOS sensor, as well as the choice of selecting bit-depths at 12-bit (4,096 tones) or 14-bit (16,384 tones), both yielding incredible image quality through a full 16-bit processing pipeline. Furthermore, the D300 enables photographers to choose smaller files at faster operating speeds, as opposed to larger files with smoother tonal gradations as slower operating speeds.

Reproducing Subtle Tones in the Highlights & Detail in the Shadows

Another photographic breakthrough occurred, the introduction of High Dynamic Range (HDR) photography for the average user. Although introduced in the 1930’s, through today’s software and the use of high-end digital cameras, HDR permits the photographer to capture a much wider range of light than normal photographs display. The photographer can choose (via various software, e.g. Photomatix or Dynamic Photo HDR) to produce a ‘normal’ photo with extended dynamic range — or photographs that look ‘extreme’ and almost as though they were drawn by graphic artists. For a nice article on HDR, please click here.

So this is my first attempt to start my blog.  I intend to document my journey through photography.

Please feel free to contact me at my email:  R.Tom.Sizemore@1972.usna.com

Here is an example of my photography.  This photo was taken with a Nikon D70 at my parent’s farm in Clay, West Virginia.  My father has an apple orchard and there had been a fairly decent snow storm.

And, here is an example of some architectural work – a building in Washington, DC.

And, finally, here is the Memorial Bridge in Washington, DC.  I took this picture around 5 AM one cold morning!

I hope you enjoy my photographs.
