Once in a while it is good to use a completely different treatment than is usual for a given genre. The aim in macro photography is to get as sharp and as noise free (clean) an image as possible.
In this case I thought the subject matter would work well with the opposite approach so reduced it to black and white and added grain to further degrade it.
This gives the image a 50′s ‘B’ movie type appeal and really focuses attention on the massive (even by insect standards) eyes.
A quick note about adding grain. This is the one area where Lightroom 4 falls down in my opinion. The grain it adds looks extremely artificial and seems to sit on top of the image rather than being a part of it. I much prefer Snapseed’s version.
