Light blaster

Amazing , but sadly not for us unless you have a Canon or Nikon lens around link

The need to create slides for this is going to be the Achilles Heel.

Some method of flashing digital images into a scene is a whole new level and would be great.

I think it would be worth getting an old inexpensive Canon lens to try this product, or you could actually try and recreate it yourself with a bit of diy. It's actually a simple (but ingenuous) idea. Some one came up with a very similar concept which used an old camera body as the light blaster... Try googling 'fulgurator'.

By using an old slr body you could actually use the winder to cycle through unmounted slide film!

Not really, Smeggy!!.. Places such as Rymans sells A4 plastic film for overhead projectors that you can print onto from an inkjet printer, so you could easily recreate your own set of slides on one sheet! All you'd have to do (after printing your slides out) is to mount them in 35mm slide mounts (if they need to be mounted prior to using in this gizmo).

But the technology used here is basic, so it's very cheap. There probably isn't enough demand for this to make it worth the r&d of doing it entirely digitally. You can of course get slides done from digital images.

The old film way was to use rear projection.

A green screen would be more use.

I would expect a Canon to Pentax lens adapter to work, but
it seem a very silly idea ...... more of a toy for kids.

Why not butcher a broken Pentax mount camera and make a DIY version?

I have a very beaten up K10D that may just do the job...


Where's Don????

Not at all, just buy an eos to pk adapter off ebay for around £6 and use an existing Pentax lens.

Sounds interesting, thanks for the link!

The problem with front projection is that you have to
overexpose the subject to get a decent level of light
on the background. You really need a special Scotchlite
rear screen.

It's unlikely that a flashgun would be bright enough.

What are you talking about Algi?

Have to love the assuredness of your 'pronouncements'!

You light your subject with flashes, and use a flash for the background (via the blaster). You can control the output of the flashes to balance the light as desired. This is different from using a normal projector, where the light output is typically low (especially if using battery powered ones, which are feeble).

Imagine a scenario where you used your flash via the blaster at full power, and your 'subject flashes' at 1/16th or lower.

A green screen is not the same, because this product allows you to project ONTO walls, blending the texture with the image, and even project shapes over your subject like this.

Do a google image serach to see how people are (successfully) using this product.

For it to work properly the camera lens and the projector lens
have to be on the same axis. This is a Pro system...

Most pro's who tried these systems years ago were far from impressed

Algi, you are missing the point of this completely. Front Axial Projection was an entirely different thing and it didn't work very well anyway.

Algi you can project from whatever angle you please, think of it like a Gobo, not a system for 'photorealistic backgrounds'.

Excuse me for direct linking an image from the Lightblaster website, but it's apparently the only way of getting the point across.




People have been experimenting with OHPs, slide projectors and digital projectors for ages. The lighblaster does a similar job but is portable, cheap and uses the much brighter light of a strobe. Is it a bit of a gimmick? Maybe, but it's a simple and cheap piece of kit and very effective.

I was thinking it might be great for projecting onto backgrounds like buildings with the Light Blaster behind the foreground subject matter

That looks terrible and about 30 years out of date

Much more can be done digitally nowdays.....
