Bullet

Digital Art

Looks like fun. An exciting creation.

Quite extraordinary. I'm even more impressed if this was faked than if it was set up to be taken in synchrony!

Regardless of the timing of the shot, or the movement of the glass. The meniscus should remain horizontal. Gravity... Cool imagery though.

this is an excellent picture

Perhaps a more accurate title may be in order. Neat shot nontheless(I missed some hyphens somewhere didn't I?)

err Correct a title of pellet would be better. Oh well not being a fire arms expert maybe you will forgive me.

 

The image is not a straight shot it is made up of 3 images and a few hours in photoshop.

(no gun was used and no glass was broken in poducing this)

 

I have been told that the water level looks strange in the top of the glass. I would have thought that with the speed of bullet (opps pellet) the water would still be in the position that it started and would not have had time to settle.

 

Well that is how the shot was planned so if I got it wrong then I am sorry.

 

I think the smaller entry on the right with the back much larger (on the left) is correct which would have also caused the top glass to tilt in the way shown.

But if anyone has any views on this I am more than willing to hear you out.

This is a good picture, but that aside, I don't think you are right about water not having enough time to settle. I mean, yes, perhaps, in reality it wouldn't have enough time until the bullet is long gone, but the glass and the water in other sections of the picture also wouldn't have enough time to move that far. Your photo, generally speaking, looks like a much more advanced stage than the time when the bullet just travelled thru this glass of water. Perhaps "much" means only 1/100s, but always ;-)

 

So, let's ignore the bullet / pellet for a while. Look at the amount of water you've placed outside the glass - it made its way out already, so it should be replaced either by vacuum / gas (which we don't see there), or sucked from the top of the glass causing some very violent flow that would affect the surface in some way. Actually, I guess that the flow would be so violent that pressure in some sections would be lowered sufficiently for water to evaporate, so we're back to gaps filled with gas. Water does not stretch, you know, and there's no gap on your picture. If so much water already leaked out, the remaining water can't just keep still.

 

That said, I don't think that the water would just 'follow the bullet' this way anyway. This looks more like a running water, not a water accelerated to a speed faster than sound. I would expect a very serious spraying instead - it would make more sense to put few thousand tiny water drops on the scene. Maybe it would be less romantic, thou ;-)

 

Another issue, as mentioned earlier, is that I doubt that glass and water would move that far (and the water would have enough time to start falling down) when you still see the bullet / pellet soo close. Remember that for both water and glass, most of the energy would be used to break the existing structure. It would start moving significantly slower than the bullet, while on your picture, it is maybe two-three times slower. Hmm, don't think so. I guess all you should see is a hole, some cracks, and a bullet trail. But I can be wrong.

 

Finally, I don't think that the trail left by the bullet / pellet should be a straight line. There would be quite serious turbulent flow for a while after this.

 

Enough pointless remarks. Good picture, did I say that? I just think that if you are trying to be a perfectionist, you should pay more attention to tiny details like the physical properties of the matter involved, energy distribution, etc. Remember that the scene involves tremendous pressures, speeds and forces, it does not really look like a glass full of water hitting a floor.

A few additional thoughts: This doesn't really look like a glass just hit by a bullet; rather, it looks like a glass that's just been whacked with a sword. A bullet hitting your average glass of water at an average bullet speed would be traveling too fast to create any great visible disturbance other than an entry and exit hole, some very localized cracking and a small outward spray of tiny glass fragments and aerosolized water at both holes. Of course the water would begin draining out to the level of the holes, but not in any violent fashion. In the picture, the water trail following the bullet out, though quite beautiful, is not realistic--any water droplets trailing along in the vacuum and eddies behind the bullet would be left far behind and probably only make it a couple of inches in a fine spray. The bullet would likely be completely dry by the time it had reached this point in the frame and not even have the "jet stream" you've shown--at least not a visible one. I certainly don't know how hot bullets get while traveling through air, but I'd bet it's hot enough to vaporize any water clinging to their surfaces. I think only larger and/or slower moving objects would create the sort of trauma you've depicted here. But...this is still quite visually stunning and artistically pleasing. Very impressive work!

Intriguing. Well composed. Quite a pleasing effect.

Regardless of all the mindful evaluations listed herethis is an example of excellence in graphics art by one who seems very skilled in applying all the benefits of the software layers.

Very nice composition and good Photoshopping. It doesn't look real, but so what? (To see what it would look like, fire a pellet or .22 short at a glass of water beats theorizing.)

I wonder what I would think if I were one of those water skimmer bugs on top of the water? I'd be scared, right? Or, if I could catch bullets in my teeth, would that one, ok, the pellet, would it be wet? Just a few questions that popped in my mind.

This is the closest "real" picture I could find. The container is aluminum instead of glass, but I think the effect would be more or less the same.Yanked from http://www.ammoman.com/gunshots.html

Actually if the bullet did hit the glass, the bullet would send a shockwave through the water causing the glass and water to burst outwards in all directions. Otherwise known as "hydrostatic energy". The image would look more realistic if the glass was empty.

Still its a neat image.

And I've been breaking real glasses all this time like a chump?

Very nice job, but as others have pointed out it takes liberties with physics. Search the net or your public library for the name of Harold Edgerton, the man who invented the beginnings of our electronic flash units. He started trying to harness the power of lightning and was able to take pictures of this sort in real time (very short intervals). His pictures include one of a bullet going through three balloons in a row. The last has only the bullet holes, the second some signs of fracture and the first to be penetrated is beginning to collapse elastically. He also invented a way to take pictures of the center of an exploding nuclear bomb, capturing some tiny exposure and used regular explosives to force a lead plate in front of the film before the radiation from the bomb could fog the film. If you cannot find any reference to him, contact me and I will dig out the title of a book or two from my library.

Sorry to say this, but this is not a credible phenomena. It looks like bad science in action. There's no fluid cavitation. There isn't even any deformation on the pellet. However, I give you credit for the amount of work that you must have devoted to this. But you should look at the Edgerton photographs.

Someone else already mentioned Dr Edgerton. He and others did similar shots so there's plenty to look up. As for the PS work, I think to try making a convincing version of this you'll have to create a lot more detail for the back spray at the entry, the exit spray and the fracturing of the glass. You're on the way, but it'll take some more time and a little research. Keep it up and I look forward to seeing the result.

 

In fact, if you rework you image, let me know and I'll try shooting the real thing for posting. My strobes won't match edgerton's 1 microsecond, but I can get about 50 microsecond bursts.

Being an avid shooter and having shot lots of items with water in them most of the water would have gone out the top of the glass with the large opening it has. If it was closed or a small opening it would have blown it all apart from all sides. Also water will rapidly slow a bullet and deflect it. The bullet would still come out the other side but not in a straight pattern with the entry point. I hope this helped in answering your question. Excellent job on the picture though. I think it is very creative especially since it's all done in Photo shop.
