These are some shots I did with a modified infrared camera I had custom built a few years ago.
I am going to be experimenting more in this area soon. Applying HDR and some of my lighting tricks.

You may ask What exactly is infrared? and what needs to be done to the camera?

well the digital imaging sensors in most cases are just as sensitive to infrared light as to visible light. Cameras are built to stop infrared light from affecting the image by placing a hot mirror filter in front of the sensor that then blocks the infrared part of the spectrum while still allowing the visible light to pass.

To get Infrared you remove this hot mirror filter and replace it with a custom infrared or clear filter. Then you have to adjust the focus, to a lens you choose to be your main lens.

Why is this better than using a infrared filter in front of the lens?

Well the internal hot mirror filter blocks most of the infrared light from reaching the sensor, And that is  making the exposure time much longer then usual. And will requiring a tripod. And long exposures makes it difficult to photograph people and anything else that might move.

Also because you place the opaque infrared filter in front of your lens you can’t see to well to compose and focus, making it even more difficult and time consuming to take each shot.

I love shooting people and carrying a tripod everywhere I go works great if you are shooting landscapes all the time. But by the time you get a tripod set up to shoot everyday people the moment is gone.

Enjoy and God Bless

Tamron was originally slightly late to the party in marketing an ultra-wide zoom for APS-C/DX sensor DSLRs, with the company’s 11-18mm F4.5-5.6 appearing in June 2005. This lens turned out to be the last in a flurry of releases that also included Sigma’s 10-20mm F4-5.6 DC, Tokina’s 12-24mm F4 DX and Canon’s EF-S 10-22mm F3.5-4.5 USM (Nikon had stolen a march early on, with the 12-24mm F4 DX appearing two years previously). With all of these competing lenses offering more compelling specifications in one way or another (i.e. the wider zoom ranges of the Sigma and Canon, or the faster constant maximum apertures of the Tokina and Nikon) it’s perhaps not surprising that Tamron has now become the first to introduce a second-generation lens in this category, with this, the SP AF 10-24mm F3.5-4.5 Di II LD Aspherical (IF). Announced at Photokina 2008, the new optic clearly aims to trump its rivals with a significant boost to the specification; the zoom range jumps to being the largest in its class, and the maximum aperture is increased by two thirds of a stop throughout the range.

Tamron has managed to deliver this upgrade in a lens only marginally larger and heavier than its predecessor, and the optical design required to achieve such a feat is suitably impressive. The formula features 12 elements in 9 groups, with a plethora of special elements to minimize aberrations; namely one high-precision, large-aperture glass-molded aspherical lens element, three hybrid aspherical elements, two LD (Low Dispersion) glass elements and one HID (High-refractive Index) glass element. The design also promises enhanced peripheral illumination (i.e. lower vignetting), combating a common problem with ultra-wide angle lenses, and improved coatings to minimize image degradation due to flare.

The 10-24mm enters the market keenly priced to compete with similar lenses from Sigma and Tokina, and is therefore substantially cheaper than the wide angle zooms available from the camera manufacturers themselves. This combination of high specification and relatively low cost will no doubt appear compelling to many potential buyers; let’s see how its performance measures up in actual use..
