  Q. IR Conversion

Asked by Dana Bergerstock    (K=-227) on 10/25/2005 
Anyone looking to have a canon Digital SLR IR conversion done?
Canon D-60 infrared (IR) modification:

The (CCD or CMOS) are very sensitive in the near infrared, the manufacturers (Canon) put a infrared blocking filter in front of the CCD chip.
This infrared blocking filter blocks out most of the infrared light, if you want to do IR work during daylight you must have this filter removed.

Modification:
?WARNING? This will void your camera warranty!
I remove the infrared blocking filter and replace it with a filter which lets all available IR light through while filtering the rest of the light spectrum out. This filter which replaces the factory infrared blocking filter allows you to focus or autofocus without a IR filter on your lens. Thus you have a totally IR Camera that can be handheld in daylight with shutter speeds of 125th of a second and apertures of f8, Just like a normal digital SLR, Without any external filters.
The Canon D-60 is a professional digital SLR camera. Because of the nature of the IR enabling modification, I do not recommend this camera mod to anyone who does not fully understand the implications of the modification.
The IR mod camera will have an internal 715nm IR filter with an antiflection coating. The 715nm filter performs similarly to the Hoya RM72 and Wratten 89B.

Modified IR Camera
Camera can take IR pictures (Yes with no extra filters)
Camera autofocus will work with IR pictures (Yes)
Camera autoexposure will work with IR pictures (Yes with Exp Comp Adj)
User can see through lens when taking IR pictures (Yes Filter is internal)

When taking ?normal? daytime photos with the modified camera the images straight out of the camera look reddish. To compensate for this, you have to use a custom white balance setting. Instructions on this can be found in your owners manual
Page 66 or the canon website. You also have to set your metering mode to partial, as explained on page 61-62 in your manual. These settings will be applied while I have your camera. You can experiment with the settings to meet your personal shooting needs.
The Canon D-60 meters light through a separate light sensor. The typical consumer cameras use the camera's CCD to set exposure. Since the Canon camera has a separate metering circuit, the camera does not correctly automatically set exposure. The user must manually set the Exposure Compensation (EC) function. The amount of correction will vary depending on the ambient infrared light.
I recommend the IR mod because you will be able to see through the lens, auto-focus and shoot in automatic modes as long as you dial in the exposure compensation needed beforehand. (Page 77 in your manual)
I will return your camera to you along with 2- 4x6 prints that were taken with your camera after modification. Once you download your images into your computer, you will have to convert them to monochrome and adjust your black, whites and neutrals, using selective color to meet your personal taste.

I can modify your Canon D-60 for a $400 fee + return shipping & handling ($20 for UPS ground insured within continental USA)
I am offering the fastest turn around time available through the internet. Once I?ve received your camera a one week turn around (plus shipping time back to you) should be expected.
