Just thought I would drop a picture on here with some interesting findings......... Yeah !, I know its been done before, but not everyone has tried it, or even seen any results. I so so so want to buy a 10 Stop ND filter (Lee Big Stopper) but thought I might try the cheaper alternative. This picture was taken using a grade 10 piece of Welding Glass. The image was a 30 second exposure at f4.5. The day itself is cloudy and bright with a very very light breeze.
The image was what I set out to acheive with the cloud blur, and the exposure is not too bad.
The Welding glass has been stuck into a COKIN P Filter holder, with slight modification (I can give more details if you so wish)
The glass has a slight green tint to it. So the image comes out of the Camera looking a little Greenish. You obviously have to tweek this in your processing software. Because of the green tinge, to adjust the blue colours, I found myself using the aqua slider to achieve the desired change. This process does not take an awful long time, but it NEEDs to be done. I think I have got the colours ok on this upload. These adjustments may not need to be as thorough if you process your image into a Black and White photograph
As like any 10 stop ND Filter, these filters are really really dark so you can hardly see through this welding glass. You may have to compose the photo first, slap the camera into Manual Focus, fit the filter onto the lens, and shoot.
Now the big question...... Would this stop me from buying the proper filter? Hmmmmmm probably not. It may be a good stop gap until I can afford the real thing. I have heard some great things said about the lee filter system, and I am saving up for the bits and bobs. But in the meantime this could be be fun until I get my pennies together.

Oh, I forgot to say.......

Cost of the Welding Glass? £1.35 ebay Purchase

I can't see your photo, but it could be my browser settings.

The problem I found with the welding glass I used was a defect in the glass that showed up in the photos, but it didn't cost very much so was worth a try.

I found it easier to set up a custom balance in the camera than adjust the colour of the pics with software.

The problem as I see it is, you are using a 7D and a 17-40mm L lens. Why oh why oh why would you put a piece of poor quality glass in front of it, does it not defeat the purpose of buying L?. Yes it can give resonable long exposure results but it is bound to reduce the quality of your images.

Depending on your filter ring size the B&W is a good alternative to the Lee system, its a simple screw in.

Hi,

I think you miss the point my friend. I was mearly pointing out the results of my welding glass photograph,

http://www.ephotozine.com/u75399/gallery/1602812


and that it could be an option to those who cannot afford, or (like myself) are saving up for the "real thing" I also ended my post by saying this could be "fun" until I get my pennies together. I was not seriously saying that this was as good as the big boy filter companies

However, I could add that I could argue, that the present filter system I have is not much better than the welding glass option, judging by the HUGE colour casting I get. And they are a well known high street name.

I have though of B+W but not sure I could deal with the screwing in and out of the lens in and between photographs. I would value you opions if you have tried one of these filters

Thanks for reading and replying to my post,

Peter
