For less than $10 you could get a step-up ring and keep your finger out of the frame.
It looks to me as though the IR + full spectrum shots have a similar effect on the clouds that a yellow filter does in B&W.

If people actually care one way or another, let me know and I'll either continue or stop posting links to sets like this. The clouds a couple of days ago looked quite interesting, so I tried photographing them with the IR camera, both in full spectrum and with the IR filter. Since my filter is a 77mm and the 18-250 on the camera had a 62mm thread, I was just holding it in front of the lens, hence my finger in the lower right corner of a lot of the shots. I was doing some pretty severe bracketing when I took the photos, because the JPEG histograms are for shit when it comes to telling you if you're actually clipping on the sensor. I tried a variety of processing techniques in lightroom on the shots taken with the IR filter. Processing these photos is going to be very situationally dependent. By definition, you are not going to get anything that looks natural. Since I snuck out into the parking lot in the afternoon at work to get these shots, I didn't spend the time I would have liked, experimenting with the polarizer with and without the IR filter for the cloud photos. I suspect the eventually, the ultimate technique would involve multiple shots with both IR only and visible only filters on the camera, and then compositing them in post production. Since I couldn't even play Mark Roberts in a high school play, I'll leave that tricky photoshop shit to others. http://www.fluidr.com/photos/ellarsee/sets/72157635169672192/ -- Larry Colen [email protected] http://red4est.com/lrc -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
