Have you seen these Infrared Photography pictures?

In this second article about Infrared Photography I will cover the Super Blue filter by  Lifepixel. When I sent my Canon 50D for Infrared conversion I had multiple choices.  I chose the Super Blue filter.

The Super Blue filter is an interesting choice.  The blue color and infrared wavelengths are going through this filter.  This means that it is possible to have blue sky along with the typical look of Infrared Photography.

This has a drawback.  With some lenses, infrared wavelength does not focus on the same plane than the blue wavelength which results in chromatic aberration.
Another advantage of the super blue filter is that I still can shoot pure infrared picture with the help of the Hoya RM72 Infrared filter that block wavelength below 720nm.

This picture is exactly the same that I published on the earlier post on this topic.  I removed the Hoya RM 72 filter and took another shot of the same scene.  This should give you a good understanding of the differences between a standard IR filter and the Super Blue filter.
As you can see, the “before” picture is purple.  This is the result of blue and red.  By using Adobe Camera Profile generator I was able to create a profile that bring this purple file to what you see in the “after” side of the picture.

While a black and white conversion was possible with this raw file I did prefer this rendition.  In some case the blue is over-saturated.  Should this be the case, reducing saturation create a more realistic color rendition.
