More infrared from Palau. This time I used Efke IR 820, Expired 3/2013. This film doesn't give as much of an IR effect with a red filter as Konica 750. I assume that's because it's further out of the red spectrum and more into the IR. It still gives dramatic skies and sometimes I get white foliage. I think next time I use this film I may give it a little more exposure to see if that helps. Developed in HC110 Dilution B for 7 minutes.

Yep, the red filter doesn't filter out all visible light. I have a filter to get the full effect out of Ilford SFX and it's pitch black. I've never had a chance to try it out.
The Efke is sensitive up to 820nm while the Konica is to 750nm. Ilford SFX is sensitive up to 740nm. Just as a comparison, Kodak HIE was sensitive up to 900nm.
I once saw a plan to build a IR sensitive light meter, but it needed to be calibrated by wasting a roll of film.

I've had good IR results with HIE using a red filter, much better than Efke.

It's probably actually due to the very different spectral sensitivity curves of both films.
HIE has a very deep dip in the greens before going back-up for the infrared.
The Efke has a more even spectral spread.
Check page 9 of this data sheet (https://www.maco-photo.de/files/images/MACO_TA820c_ENG.pdf) and you'll quickly see why this is.

Great shots as always Bryan
Early autumn we had a week in Cornwall and I managed to catch some surfer action - not that I went into the water - in between the sun and showers. Mamiya C3 Ilford FP4+ i in ID11

Those tropical photos of the beaches of Palau and Cornwall make me want to jump on the first plane to the coast. It's been foggy and grey here for weeks.
I've been using my Instafrankenroid to document my hobby projects lately. This is a small side table I just made for my mother-in-law for her birthday.

I have not shot anything for the last two weeks, crap weather with rain and wind and now we've got snow as well. But I've spent some time scanning old films all the way back to 1972, some not scanned before and some scanned with a lo-fi scanner from the digital stone age. Here's one from my student days, most likely from the last day before Christmas break in 1973. There's a lit candle on the desk and advanced maths on the blackboard. ;)
This was shot with my first camera which I bought secondhand in 1972, a Nikkormat FTn with a Nikkor-S Auto 50mm 1:1.4. Shot on Kodak Tri-X developed in Rodinal in the school's darkroom.

Happy Weekend! Great shots everyone! I would swap the cold rain for one of those sunny beaches right now.
I have some autumn colours on Kodak Ektar.

You picked up the colours of Autumn well there. Nice ones.
