BTW, for those wondering what the easiest way to mount such a filter to your camera.... if your lens has a petal hood... simply mount the hood on reversed, as you would for storage, focus manually, then use two small rubber bands to hold the filter onto the lens hood......:wink:

I just cancelled an order I placed with WarehouseExpress in March for a Lee Big Stopper 10 stop ND filter and bought one of these Parweld glasses for £2.00 delivered. The Lee would have cost about £100.00. I figure for the amount I'm likely to use it, the welding glass will do to try out the tech...

If you then take the welding glass to your local glass merchant he'll probably cut it to size for you for another few pence. (Here I'm thinking of a Cokin P filter holder). Some will even cut 52/55/58mm circles for you to fit a circular filter mount Bernard

I expect they'll say they are for welding Bernard, and not photography :lol: For what its worth I think a number 10 is around about a 14 stop filter. The lower the number, the more light it lets through. So maybe a number 9 is about 12 stops, at a guess. :wink:

Mine arrived yesterday :D Now, anyone know what strength ND filter I use on the Longtime app as the filter is practically black to see through ! When I ordered my set of welding filter I tracked down the formula for the different shades & calculated home many stops they equated to. However in us...

I have a filter labelled ND16, bought some 30 years ago, which I had hoped to use to take "people less" street scenes. I never did figure out, correctly, what change I needed to make to my exposure time for this filter and no decent pics ever came out. After wasting no end of film it was consigne...

Geordie, get something like this for your next attempt . I tried elastic bands and wasn't very successful. I then used electricians insulating tape to secure it to an adaptor ring I found lying around. Its on there semi permanently now, and I just screw the filter on and off. I will get around to...

Is there any chance of members posting more of the trial photos this is an interesting apprroach and as said worth the few pounds just to give things a whirl. Regards Ian Two of the few I've done, on a bright day back in February: According to my records these were with a shade 8 (My...

Unless you have a specially modified camera IR & UV response is very much less than visible. So the variations with non-vissual light are not significant. I have a bog standard K10D and have lifted the figures from a photocopy from the manufacturers and compared their figures with a table from Wiki...

Lovely garden, but is this an appropriate scene to test such a filter? Those are actually the same shot 35mm - f32 - 1/10 - ISO400 (check the EXIF data), which is why I can't see any difference :lol::lol::lol: You've linked to the same image in both cases. I'd thought that the primary use for ...

My £2 bit of glass arrived today. I found it fits into a spare Cokin filter I have (no idea why I have it as I don't have any Cokin filters that fit it. The ones I do have are from 25 years ago...) I just need to buy an adaptor ring now. I'll probably go for 52mm and 58mm rings so I can use my ol...

Wet Jeep
I needed to get a quick shot of the car this evening to send off to someone, but typically it started to rain so it stayed in the garage. Instead I decided to turn a problem into an opportunity and took some shots of the rain on the Jeep instead, exploiting the water resistance and shallow DOF virt...

Thanks Stefan. The car is a titanium colour (i.e. fairly colourless), so most of colour came from the green and red from the trees and brick wall. I think most of the effect came from CP filter and pulling up the vibrancy slider in Aperture 3.

I hope to have that camera soon, KM, any news for me? I have bought the Kx, so the Km is ready for a new lease of life.....:D I'm still awaiting a quote on the filter glass from Basildon, but my confidence with the principle of tinkering with the SR gubbins is growing - I believe I can take it all a...

Two IR shots - two treatments
Well, the attempt at colour channel swapping was an experiment. Since this is with an R72 filter there is false colour, so I wanted to use it. However, it is still false colour no matter how much PP is done... Here's the first one with the colour removed - much more in my comfort zone of PP: ...

Hockley Viaduct - in IR
I've been following your IR posts, Richard, from your recounting of the conversion of your camera to IR &, I have to say, I'm hooked! They are beautiful, ethereal,& show the world in an entirely different light(!) Can this "effect" be achieved with a non-converted camera? Can a filter be used? W...
