Hi to the forum. Are there any filters for x-ray photos? I have an Olympus c730.

Can someone explain me how the whole thing works? Thanks in advance.

If you believe that I have posted it in a wrong section please move it.

If you are talking about a filter that produces x-ray photos, I am fairly certain that no such animal exists. If you are talking about a digital software filter for PS or PSP there may be something available the produces an "x-ray like" effect. However, for a true x-ray photo, you need the gamma or x-rays produced by an x-ray machine to be able to penetrate the subject and give a "shadow" of the interior. Medical x-rays are just shadows where more dense objects block varying amounts of the radiation from the film.

I saw some greenish pictures and the guy said they are x-ray pictures. I know that they can't be real x-ray pictures and all the technology behind them. I thought he must have used some kind of filter, or a special mode that his camera supports. This is what I'm looking to explain. Is there any filter that gives that effect? Or perhaps if you shoot using a night, probably, mode do you get that result. Unfortunately I haven't got an example to post. I will look again and if I find something I'll post it. Thanks

Are you sure he didn't say Infrared versus X-ray? Some of the Sony models have a "night shot" mode that produces greenish pictures (the light source is Infrared from the Camera and allows photos in total darkness).

He said x-ray but I suppose he meant infrared... because I think he mentioned something about sony camera too.

So it is a 'special' mode that sony have...?

Ok thanks probably I won't be able to make it because I've got an Olympus.

Yes. Most modern Digital Cameras have a Hot Mirror Filter (IR Block Filter) in front of the sensor to reduce IR light. Some Sony models have a feature that moves the Hot Mirror Filter out of the way.

In Night Shot Mode, the camera uses an IR Emitter to illuminate the subject (good for closer ranges) with the IR Block Filter moved away from the sensor.

This allows the camera to see subjects in total darkness. However, the photos are rendered in a monochromatic (greenish) color.

there are some filters out there that block UV and let IR pass
you end up with a green image
IR passes through some cloth
thats what they are calling X-Ray
you need a Nite vision camrea to use it
they claim Sony Handycam works

Wow, an Olympus c730 can detect ionizing radiation? Call your local radiology department, they're clearly overpaying for their equipment!

Don't you find it kind of a drag to carry around a portable generator and cascading microchannel plates to generate the X-Rays, though? I mean, that's gotta be pretty heavy, and X-Ray generation isn't very power effecient.

This sounds like the ads on the back of comic books for x-ray glasses so ou could see through clothes.
