Remote camera flash- through double glazing?

I am photographing wild life and wanted to buy a remote flash and place it outside.

Will it work through double glazing and will its signal range be reduced much?

I might want to place the flash 25m from the camera...

Will the camera be behind the glazing?!?

Yes, £1500 camera and lens indoors or in shed, remote camera flash in the garden near subject.

I got a lot of flash bounce untill I shaded the glass around 1" above the lens with the lens touching the glass. But I wanted to snap stuff further from the house. the camera is also noisey. Animals seam more frightened by the SLR noise than the flash!

I have a Pir and a wire triggering the camera.

I might have to add a power socket to the flash to keep it working on standby all night

the animals can hear the (£1500) camera behind double glazing?!? Must be a beast of a camera.

Through any window the shots are going to be 'meh'.

Judging from another posting it is probably a £150 camera, not a £1500 camera.

Radio -RF will be fine. Look on ebay - lots of cheap Rf triggers their.

IR based stuff - like the offical Canon system - probabably won't work.

I have ordered a RF trigger

I have a number of cameras, a fuju pocket camera
an olympus c720uz both well out of date. the fuju f100 ? is a fantastic tool.


My cannon 450d was around £500, 500mm lens was around £900.
I tried placing the camera outside and the there noise of the camera 3m from the subject bothered them.
I put food on a row of posts the birds took the food from the other posts and were cautious of the post with the camera near (camoflage net might have helped) when the camera triggered they often aborted the landing. by using the long lens I can get close up shots. I want to use remote flash to light the subject.


Also having had a few theives in the garden this year I am very reluctant to leave my camera out side. not to mention rain or dew.

The only noise from the camera should be the shutter- which by the time the birds would have heard it, would be too late for them to fly off. Do you not agree?!?

If your 500mm lens cost £900 than no wonder your shots are poor!!!

Tony, thanks for your PM, I'm not attacking you at all, just pointing out that a lens of that spec of an acceptable quality usually costs a heck of a lot.

You didn't say whay noise exactly was scaring the burds. I've tried kinda what your doing but with poor success due to a cheap zoom lens amongst other factors.

Just trying to help you brother.

What that man said, it's hardly likely to be equal quality to the Canon 500mm f/4 IS L-series for sub-£1k is it? (Or the hillariously green $25,000 Sigma 200-500mm f/2.8 for that matter, just for further if somewhat extreme price comparison)

As for RF triggers I've never used them but a mate got some cheapish ones that were more trouble than they were worth, misfires with a handful of no-fires thrown in for good measure.

[nitpick mode]

If the lens in question is fixed 500mm focal length it is a prime telephoto lens, rather than a zoom.

has the op abandoned the thread? Post some pics if you're still keeping an eye on it!

I think we are into different sorts of photography.
I want to record whats going on rather than produce award winning magazine shots.

The project is still ongoing, I am waiting delivery of RF flash control.
I have pir trigger working wery well on wildlife from a sparrow upwards.

I have also developed a tremble sensor that will trigger with the landing of a bee. I want to try it out on an active mole hill.

I have been shooting through glass and I use a lens hood and a sheild 2cm above the lens to prevent the flash bounce, however even the short lens creates a shadow in the picture. I really need to get the remote flash set up.

I have multipe shots of the fox stealing the bowl of food. bowl never to be seen again. Cat v Fox...
The night time slug activity is scarey. http://www.facebook.com/album.php?ai...39137267&saved

I also have an owl who drops pellets in the same spot regularly near the house I want to capture.

I have just recieved an IR beam kit I hope to set up across his path to trigger the camera

Tony, think I may have misunderstood yr thread a tad- think I thought you had trouble with noisy/poor IQ shots!!

Any chance you could post pics of your sensors?!?

That's an insane slug problem btw!!!!!!

If I've mentally imaged your set-up correctly, I'd have thought short lenses are MORE likely to see a shadow at the bottom of the image due to their wider angle of view.

I am using the standard 18-55mm canon lens fitted with a 9cm diameter rubber lens hood with a bit of 100mm x 100mm black plastic on the top that touching the window glass to prevent the cameras flash rebounding through the double glazing. It works but it creates a shadow.
