p.1 #1 · p.1 #1 · Stacking Square filters


I don't want to spend the $100+ on a B+W 10 Stop ND filter or a Lee Big Stopper as I'm just starting to get into long exposure. I've noticed that on square filter holders you can stack multiple square filters together.

My question is does anyone have experience stacking multiple 3 or 4 stop ND filters together to achieve a 10-stop filter effect? If so are there any problems with vignetting or light leakage between the filters (I assume the filters aren't stuck completely together and there's space between them). I'll be using this setup on a Canon 10-22

I stack square filters. I use cheap plastic Cokin filters, so what I've found is you start to lose some image quality with each filter you add. If you have 1% distortion with one filter, then you'll have 4% if you add three more. Cokin tends to add a slight color cast too, but you can mostly correct that in post.

agree with pixelrandy.......you will begin introducing some visible contrast loss and sharpness loss as soon as you start stacking multiple resin (or even high end glass) filters on front of the lens.

You also run a MUCH higher risk of off-axis glare in the image, due to refraction at the extreme capture angles of the filters.

Why not just get a 10 stop resin filter from HiTech, they are about $40.00 from B&H or Adorama.

I've ordered the Hitech, but it was $140. The Lee Bigstopper is 6 months back-ordered.
I've heard/seen in some reviews that the Hitech filter has a pretty severe blue color cast.
Have you noticed this? Is it easy to correct?
Here's one of the reviews: http://blog.jholko.com/2012/06/24/battle-of-the-big-stoppers-lee-vs-hi-tech-10-stop-nd-filter-showdown/

I should be getting my delivery of the Hitech next week to try it. Hopefully the blue cast isn't too severe. Maybe it will be correctable in Photoshop/Lightroom?

surfmonkey; would like to hear about the Hitech filter whrn you get a chance. I have read that the clolr cast depends on how your camera reads it so it can differ from camera to camera or brand to brand.
Best wishes.
