Target Before and Afters?

Afternoon all.
I was wondering if anyone has any photos of a target before and after they've shot it, or even in between shots.
I'm having a tinker with a, potential, shot recognition and grouping measurement toolset and could do with a few real-world images to see if it's feasible.
Ideally they need to be shot from exactly the same position and angle.
Cheers

You can't park anywhere these days!

Demonic, would it not be possible to just get up close to a small target and shoot at it with an air pistol?

Are you trying to do something like this

Similar knewmans, but free and more universal

I have used this program. Take a pic of your shot target with your phone / tablet then work it out later. I found the program simple to use.

That looks excellent and very close to what I wanted to achieve.
My plan was to use a battery powered Raspberry Pi and camera hosting a web server that you could wirelessly connect to from your phone or laptop etc and see where your latest shot hit, then measure the grouping.
I got as far as being able to compare images, getting an output that highlighted any differences; new bullet holes.
I also found some software to measure the grouping, though not automatically yet.
I was hoping opencv could do it all but I'm not enough of a geek to get started with that :-)
Long run I was hoping for a system that, with a little planning, could be taken out add far as needed and used to replace markers (if unavailable or unreliable) and/or aid them in their job.

OpenCV would be my choice for something like that... Just use the PiCam to poll the target every second or something and spot the changes, something that the software should be able to do with no problems. If you are already using a Pi, I'd say you were geek enough.
I'm crap at coding, but I'm happy to help you test things if you want.

I was hoping you were going to say you were happy to code
I'm not great at coding but can usually cobble stuff together when I need to, usually for the Arduino/MSP430 or using HTML, VB etc. OpenCV is a bit much for me though as I've not spent much time on C++ :(
