« Here's How I Do B&W Infrared: Part 1 | Main | Final Reminder (Update: Sale is Over Now) »

Ctein's two IR articles are most helpful and appreciated. Thank you.

"...My go-to tools are the Topaz Labs programs: Denoise AI, Sharpen AI, and Gigapixel AI..." The same tools I use in most of my to print photographs, truly exceptional.

Thanks so much for these two very helpful tutorials! I have always liked IR images and this sale and your posts have persuaded me to have LIfePixel convert one of my cameras to BW IR. Should be a fun adventure! At the moment I’m trying to decide between converting a Sony full frame camera and a Fuji X camera. Thanks again!

99% technical, 1% emotion. Makes for boring photography.

Is "how to glue the dowels on your snooker table" next up on TOP?

[Well, it hadn't occurred to me, but now that you mention it I *could* prepare a 3,000-word step-by-step tutorial about how to develop 35mm film...my qualifications are that I tried every method known to humankind and made every single one of all the possible mistakes. --Mike]

Thanks for explaining your process. FWIW I've found shooting in IR (in my case, a Sony A7 converted with a Lifepixel 720nm filter) to present a dizzying array of approaches for rendering the IR file into grayscale. The trick is to find a way to exploit the medium's signature strengths to create a vivid image without calling attention to itself. But then that is true of most "alternate" photographic processes.

The lifepixel conversion for Deep IR I just leave on high contrast BW mode in my camera... all my shots come out perfect, but thats just me... you have to like jpgs. Also, it looks like that Leica 12mm has some IR hotspotting in the middle (reduced contrast and higher brightness in the center of the frame), prolly nothing.

Dear Taran,

So far as I've seen, every lens not designed specifically for IR is going to show hotspotting in the middle. It's unavoidable. What you want to avoid is a lens where it's so severe that you can't correct for it reasonably well in printing, or where it shows the outline of the diaphragm blades or some such. It's not too hard to get rid of a uniformly soft-edged blob that fades out. A whole 'nother thing to deal with sharp edges!
