630nm B+W 091 Filter For Stunning Faux Color Images!

B + W 58mm #091 Glass Filter – Dark Red #29

630nm, B+W 091 Filter

As we have talked about in several of my past posts, the 590nm Infrared (B+W090) is my favorite part of the spectrum to shoot in.  But right up there in capabilities is the 630nm edge using the B + W 58mm #091 Glass Filter – Dark Red #29 filter.  The 590nm tends to give you more of the yellow and gold tones (hence the Goldie name!) but at times I like more of the yellow and pink leaves in my images! Take a look at the top image, the main change are the pinks mixed in with the yellows of the leaves but you still get great blue skies and water!

This is a low cost filter (around $30 in 58mm at Amazon) and is a lot of fun to use.


B+W 091, 630nm Frequency Chart

Looking at the B+W 091 chart to the right you will notice that it has a very sharp turn on point from 600nm to 100% at 630nm and stands between 590nm and 665nm.  In my opinion it generates better Faux Color images than the 665nm filters and will do equally as well in B&W! It is a little darker than the 590nm (2 extra stops) but is still well within the hand held operational zone!

As as I stated earlier, I LOVE the pink tones that this filter will generate!  The pinks/yellows are dependent upon the angle of the sun as well as the amount of green in the leaves.  If you look on your cameras LCD display and notice greens in the leaves (or on the computer during post processing after you do the channel swap) this is where you will generate your pinks, all other leaves will make yellow!  Look at the RAW version below of the title image. The darker areas of the leaves will become green during the channel swap and by lowering the green and blue levels in Viveza during post processing you get the nicest shades of pinks!  BUT, I also want you to notice that as in all things Infrared, sometimes you get such a perfect RAW image right out of the camera that it needs NO EDITING or Post Processing to stand on its own!  The image below is one of these rare images and deserves to be looked at for this reason!

Post Processing with the 630nm filter is EXACTLY the same as with 590nm except for the fact that you will see some areas in the leaves that are green after the channel swap.  When you open and run Viveza, you simply select these areas and lower the green and blue (blue is just a little) which will give you the really nice pinks.  All other processing is just the same as with the 590nm!

OK, let us take a look at some example images made at 630nm!  Please, let me know what you think of these when compared to the 590nm images that you have seen here in the past!

As you can see from the image above, you can expect stunning B&W images from 630nm!

As stated earlier, 630nm will generate stunning B&W images!  They are easy to do with NIK Software’s Silver EFX Pro Photoshop plugin.

I think that the next post will be a tutorial on how I create my own B&W images from the RAW Infrared images.

Stay tuned….!

  1. Hello Mark, would using a Neutral Density Filters with a B+W 091 (together) on a unconverted camera gives me the same result as you have taken above?

    • Zedek, no, most of the ND filters are really transparent to IR energy! Plus the visible portion of the spectrum that the 091 allows to pass thru will poison the image itself and destroy any control of the exposure! To do this type of photography you REALLY need a converted camera. Have you considered a low cost micro 4/3 system like the E-PL1 or 2 from Olympus? You could get the camera for about 250.00 and have it converted to 590 for another 250.00 and be ready to go with a high quality low cost system that is small, light and has interchangeable lenses!

    • WOW! On 2nd thought, you do bring up an interesting point… If you place the ND filter on the lens first, then the 630nm filter the ND filter will drop the exposure of the visible part of the spectrum and allow the ir thru…. Hmmm a very interesting point! This would be worth a little experimentation!

  2. These look wonderful .I am new to infrared and keen to one day give this a try. Faux colours are great, though I feel they shouldn’t be arbitrary. These seem to reflect the bandwidths of light being captured, which makes them magical to see.

  3. I’m confused… were you shooting these with a camera that was converted to capture infrared without a filter? Or are you using the filter with a camera that has the infrared blocking filter removed?
