To all those who removed blessn900 after having this problem, I believe the fault was with an incompatibility between the version of the fcam drivers and Titan's 42 kernel.

I had the same problem until upgrading.

The recent versions of blessn900 have added a ton of features including HDR, shallow depth of field (pseudo macro), etc and the user interface overhaul really made it a joy to use.

The person/people behind dear Blessie deserve a reward IMO.

See examples and explanations of the method here:
