I'd read some things about blood spatter last year, but it sure helps to see some actual photos, doesn't it? MC's blood drops look low velocity and passive. I'm still really curious about what Mr. Klein had said in his previous interview that he felt the blood drops were arterial, rather than venous, blood. If arterial, I always used to think blood evidence showed sprays and spurts- blood leaving the body under pressure.This is an easy to read slide show about blood splatter. I find slice 30 particularly interesting because it talks about how different textured surfaces impact how a blood drop will look.
