Meeting House Series In B&W Infrared

I believe we have had a stay at home order in NJ now for 34 days! We can not even go to a park to walk. But we can walk outside in our Condo Community (with a mask). So I thought I would go to the Meeting House on the Commons in our community. It is used for meetings, concerts and various church services. It is an interesting building & Commons for photography, some of which I have posted before. So I thought I would practice some B&W Infrared Photography.  I shot a mix of multi-image panoramas along with single shot images. For this I was using a Canon R camera with a Hoya R72 Infrared Filter on with a Canon 17-40mm lens. All images were shot with the lens at 17mm. With the Canon R Mirrorless Camera Body I can actually see what I am composing/framing in the viewfinder with the R72 Infrared filter attached on the lens. On a standard DSLR all you see is BLACK in the viewfinder. So you would compose/frame your shot, then put the filter back on. Then you would manually adjust your focus point to the IR focus mark on the lens. (See images detailing this procedure below in this post). Since with the lens set to 17mm and shooting buildings my focus for all was set manually at infinity focus on the IR Focus marker. Also for shooting with this R72 filter it is necessary to photograph a white piece of paper for adjusting the White Balance when Editing your IR images.

When you Open your IR Image it has a Reddish Orange Cast from the R72 Filter. Use the steps below to convert to B+W Grayscale Image.

Since you are using long exposures because of the R72 filter, clouds seem to get an even smoother feathery look. I chose an f/stop to get a ~14 second exposure. If you go too long the clouds have even less detail which looks a little bland and gray.

Below are a series of images showing the manual setting for infinity focus for InfraRed shooting. If shooting closer than infinity, take filter off, manual focus and adjust that spot to the IR Red line on focus area of your lens. Hopefully by seeing the 3 images below you will understand how to set the focus manually to the correct IR focus point.
