Very few digital cameras are manufactured to be compatible for infrared (IR) photography, and the biggest blame for this incompatibility probably goes to lenses. Many lenses are not able to capture IR images without causing the annoying hot spot in the center of IR images. Usually appearing as a whitish or reddish circular patch, hot spots are always more prominent when using smaller apertures, and less visible or even absent when using bigger apertures.

Generally, the occurrence of hot spots can be greatly reduced, if not totally eliminated, by converting (modifying) the digital camera for IR photography.

In the following gallery of images, it is observed that the unconverted Fujifilm FinePix S6500fd produces hot spots.

In April 2010, I repaired a dead Canon PowerShot A640 camera to test its capability for infrared photography. Together with this revived unconverted Canon camera, I also tested an unconverted Canon PowerShot SX120IS and an unconverted Fujifilm FinePix S6500fd with the ever popular Hoya R72 filter.
