High speed ballistic pictures

.500S&W Magnum flame:

It really lights up the scene ;)

yet again, awesome pics dude.

question, in the video you linked to on the Desert Eagle (.44 it looks like) there is no muzzle flash, and very little smoke, why?

Hi, those high speed videos are taken with different kind of setup than our pictures. They are using high speed sensor read and we are using length of the light pulse to limit our frame. Our setup is more sensitive to light in some sense and it can freeze much faster object in great detail but the draw back is that we cannot close shutter fast enough to limit unwanted light: There may be too much light in form of muzzle flash and that flash is really visible. Big calibers like .50AE / .44Mag / .500S&W Mag and so on make so much light that the picture is dominated by it and actual not burning gas is not seen (actually most of that gas usually burns when it comes to contact with air but anyway).

Here is one example. High speed video of .45ACP usually show just load of smoke (and lots of it) but we get view like this:

It's important to understand that the flame above the bullet is in different time than bullet itself so even though they appear to be in same time and space in that image they're actually are not. And now I may have confused many of you...

And also 3D to visualize those structures:

I Gif-ed your photos for you. Hopefully that convey the 3D better, because I could not see it.

This is the original photo sequence;

This one is altered in photoshop to bring the positions closer together.

Both are 150ms offset.
 
Stereoscopic 3D seems to be most effective when the subject is centered in the image, and the camera rotates around that center in very small increments. Smaller angles produce greater reality, while a sequence of small angles makes the very best 3D effect. Smaller angles, which could be described as better framerate, making the images less jarring and easier for our brains to process as 3D images.

This article gives very good examples of stereoscopic images, with the ASCII text and the Cat being the most realistic looking of the lot.

These shots give you an excellent idea of how destructive a contact, or near contact range gun shot wound is - you can clearly see all 3 wound mechanisms, and get a great idea of the intensity of the energy involved.
