Using Photo References

This is just something I thought might be of interest to one or two people. This is the kind of behind the scenes, production, and process stuff I always really enjoy seeing so maybe someone else does too.
Sometimes when I'm drawing a page, I'll come to a panel that requires me to draw a difficult pose. Usually action shots need a reference of some sort to understand how to body moves a certain way. Most static shots I can think through in my head or pose and take a photo with my macbook.
Sometimes action shots are tricky so one place I'll usually look to find a helpful photo, is sports photography. You can find all sorts of odd poses in mid-action.

Below is an example of how I used a sports photo as reference for drawing an RCMP officer getting his brains dashed out by barrage of bullets.
I found this image through a simple search online, and reversed the photo to fit my needs for the panel and composition. Then I roughly used the image as a guide to capture the line of action and basic movement. Once I had the body structure down, I fleshed it out with the RCMP officer details; helmet, uniform, pockets, guns, etc. Then plugged him full of bullets... Once that was done, I inked it and that brought me to the stage you see the panel at in this photo!
