Crosshair lenses

hunting. What I would like is to have pictures of deer with crosshairs
showing what could have happened had I used a rifle. ANYBODY got any
ideas on how to rig a SLR to do this?? Please e-mail me at

Well, I took a photo like that two years ago. First, I shot a nice doe with my
.30-06. Then I suspended it from an overhanging tree limb using braided
fishing line so the deer looked like it was standing up. Finally, I used some
thick black nylon rope suspended in a crosshair form right in front of the deer
and took a photo with one of those round vignette things. The photo fooled my
hunting buddies after they'd had a few beers.

I would use either a slide sandwich or a slide/film duplicator. A slide
sandwich puts two slides together - one of the animal, the other of the
circular cutout and cross-hairs in black together. Just put and align
both slides in the same slide mount kind of idea. The other better
approach is to duplicate the animal slide with a black cutout (vignetter)
and the cross-hair pattern of your choice. You can either emulate the
slide sandwich, but in your slide or film zoom duplicator, or use
multiple exposures - one of the slide and the other of the animal. If
your camera allows multiple exposures, you might also try one exposure on
the animal and the second of the desired background or vignette or cross
hair pattern - but I suspect this would be harder to do with most animal
shots than with the full moon into a landscape, as it is usually used as
a trick to do that kind of static photo tricks. For the digital
illuminati, you could also scan in the critter and then overlay your
crosshair pattern etc. and provide standard output as desired ;-)
good luck bobm

use it when printing the photo. See if you can find a commercial photo
lab and see what they can do for you. The prints could also be altered
digitally to give the same results.
I don't think you can do this on camera with a filter because the
cross hairs would always be out of focus. Seems like it will have to be
added after the fact.

The only way I can figure is to have some kind of long extension device
holding a crosshairs. The device would need to be attatched to the camera
(so as to aim where you aim) and extended to at least your minimum focus
of each individual lens.
Then you would need to be taking pictures at a very high f stop to get it
all in focus (crosshairs and deer). This would require tripod and longer
exposures most likely. Unless you used say 3200 B&W and use it at 6400?
Tough any way you look at it.

Another idea ... shoot slides and sandwich an image of cross hairs
over the slide.

How about just taking a sharp scribe and draw crosshairs on the
negative? Any clear spots on the negative will print as black.
But that would practically limit you to only two intersecting
lines ... no fancy stuff.
Of course if you had your own darkroom, you could expose an
image of cross hairs over the print. You could probably get
a custom place to do this for you, but would probably be
limited to 8x10's or larger. DIY darkrooms are around in
most large cities.

I think the only way to get crosshairs on the film at the time of exposure is
to have them on a glass plate in the film gate of the camera, and at the film
plane. This way the crosshairs block exposure at the surface of the film as
each shot is made. I recall reading that this is what was done to the NASA
Hasselblads that went into space (remember those funny crosses and corners
that appeared in the shots from the moon?). So it is technically possible
with a Hasselblad. Not sure if you could fit a reticle into a 35mm SLR,
maybe it could be done with a Leica rangefinder (less mechanism in front of
the film plane), but in any case it would involve a lot of custom work. NASA
could afford it but I know I couldn't.
The earlier suggestion to add crosshairs in the printing step is going to be
the easiest, although it does smack a bit of "cheating" if the point is to
prove that you would have made a properly placed shot if you had had a rifle.
On the other hand, I know from my target shooting competition experience
that it's tougher to make a shot when it "counts" than when it doesn't, so
maybe taking a photo wouldn't actually prove that you would have made a kill,
even if the crosshairs in the camera came out exactly on the money.
Anyway, it's an interesting project. Let us know what you decide to do and
how it comes out.

Hmmm. Interesting. I don't know why I didn't think of this.
In infrared photography, some people use a very small sheet of 25A (red)
literally taped on the inside of the camera (just in front of the film
plane) so they can take action shots.
The acetate taped inside the camera allows you to see through thw
viewfinder without having to look through the red filter.
I beleive that the size of the acetate was just tall enough to fit between
those raised 'bars' on the inside of the camera that the film passes over,
and wide enough to cover the opening and be taped with a tiny peice of
scotch tape on either side.
Did that make sense? I'll include a URL to a page that describes it.
Anyway, if you didn't care about crucial image quality you could use a
clear piece of acetate with cross hairs drawn on (or even HAIRS!) instead
of the 25A.
Wow. That should actually work!
PROBLEM: You won't be able to see or sight with those crosshairs.
You will need to add crosshairs to your mirror, or get a mirror with
crosshairs on it, and then shoot some test rolls. When you get back the
pics, you will need to move the acetate around on the inside of the camera
to match what you were actually seeing.
There may be a better way to calibrate that, but I'll let someone else do that.
Yeah, let us know how this works out.

Jerry,
How about getting a special focusing screen made up so that you will see the
crosshairs through the viewfinder. This will not put the crosshairs on the
picture itself, but would give you the feel of the gun. The crosshairs can be
added in post processing.

Alternatively, you could look at using the same method used for some
1x telescope finders ("telrad") and (I believe) bombsights.
\
eye/lens----------------\----------------- target
|\
| \glass at 45 degrees
|
----- diverging lens (increases apparent distance)
|
------- illuminated overlay (crosshair, dot)
Take a piece of glass at 45 degrees - look through it to the target.
It also reflects light from an illuminated overlay (LED dot, crosshairs or
whatever, superimposing it on the target. You can compensate for the
focussing problems caused by the different distances by using the appropriate
strength diverging lens to increase the apparent distance of the overlay.
or, as another alternative, tape a laser pointer to the lens barrel (or fix it
to the flash shoe, or whatever) to put a red dot on the target.

Crosshairs on the mirror won't help: the mirror doesn't lie in a focal plane.
They'll have to be on the focusing screen.
