There is another option for IR photography if you do not want to use a filter. You can have your DSLR converted permanently to capture the IR spectrum.

This can be done by sending away your camera and a lens to be calibrated. It is very expensive, and leaves your camera only able to shoot in IR. Is your digital camera capable of infrared ( IR ) capture?

Point a TV remote control at the lens , push a button, and take a picture or look at the image on the LCD panel. The common solution is to use an infrared filter on the front of your lens. These are very dark red in colour and block out all but the infrared light to your sensor.

You can shoot UV, visible, IR and everything in between depending on the filter you use. So you can achieve all of the above images and more, with appropriate filters. The disadvantage is also the fact that . This is important to know since many light sources, including the sun, emit infrared light. A CCD color camera in daylight without an IR -cut filter will therefore see a significant amount of infrared light resulting in strange colors.

Another reason for using an IR -cut filter is the limited color correction for many lenses. Such filters can be used both over color camera lenses , and to filter visible light from IR illumination sources. Such filter stock is most easily made available most simply by having any commercial color negative film developed after being fully exposed to light. The leaders of 35mm film are ideal for this, without wasting an . Some lens manufacturers such as Leica never put IR index marks on their lenses.

The reason for this is that any index mark is only valid for one particular IR filter and film combination, and may lead to user error. Even when using lenses with index marks, focus testing is advisable as there may be a large difference between . Overall Width (Hinge-Hinge): 149mm. For infrared images that consist of a combination of visible and infrared light, we recommend the R-Infrared filter (which passes 720nm and above). Note that lenses are typically designed for the visible spectrum, .

Lens Size Vertical: 39mm. The possibility to use modern digital cameras for IR photography apparently does not only depend on how good (or bad in the best case scenario) the built-in camera IR filter is, i. There is the problem of the so called Hot Spot: modern lenses are coated to improve their performance for the . Infrared ( IR ) cut-off filters are used with color CCD or CMOS imagers to produce accurate color images. An IR cut-off filter blocks the transmission of the infrared while passing the visible.

Absorptive filters are made with special optical glass that absorbs . Additionally, hotspots tend to be worse with deeper IR filters like the 850nm, than the color IR filters , like the 590. Is the barrel on Mlenses the same diameter in mm from one lens to another or do you have to be specific for each lens barrel?
