    Great images, Peter. Are you working with a non-converted camera with just the R72 on the lens? If so, I'm amazed. I have a D850 and have shot with the R72. Got great IR effect but always with a hot spot in the centre of the image.

    Thanks, Andrew. Yep, I'm just using an R72 filter on a regular D600. By any chance, were you using a zoom lens? Did you cover the viewfinder during exposure?

    Yes, I was. Could that be the issue? Should I try a prime? I do have a wide angle prime.

    Give it a try. I've only used primes. Make sure to cover the viewfinder. According to Lifepixel, some lenses are known to cause hot spots.

    Thanks, Peter. I'll give it a shot later today. Thanks for the viewfinder tip, too!

    I have an extended silicone cup viewfinder hood. A rear Nikkor lens cap fits over it perfectly.

    I hope it works out for you!

    Peter, I tried the wide prime on a D850, with the R72, and I couldn't really see an issue. I did though, with the 87C filter. Brutally long exposures that took ages for the camera to "process" the image, before I could preview it. I'll wait for an IR day to try it again...
