ins13 Posted May 9, 2019 Share Posted May 9, 2019 Orange filter OC12 (50% on 550nm) for the startI added СЗС14 (about as СЗС24) in the hope to muffle Infrared and get more hues in vegetation. I'm not sure if it made sense. Olympus em5FS, OC12+СЗС14processing: channel replacement, contrast, saturation foggy weather Link to comment
Cadmium Posted May 10, 2019 Share Posted May 10, 2019 Yes, this is when I really like the #12 post processing better than the all-in-one #729 method.I really do miss the yellows that get transposed from visual red with the #12 process.Well done.I like the last one best.The kid with the hat is just a little scary for me, I am worried he will fall... What post process did you use? Link to comment
ins13 Posted May 10, 2019 Author Share Posted May 10, 2019 Thank you very much! :) I like it better, too. Many colors, many shades. and, уes, the variety of yellow tints. Processing in the little things is a little different in different pictures, depending on the situation and ideas.But basic steps is such:White balance depending on what to need. Or asphalt, gray stone or facemixer channels R--B, G--R, B--Gif it is necessary - auto level or auto contrast in lab mode - adjustment - curves at a and b channels for desired colors and add sharp in lightness channel by filter sharpen - smart sharpenagain RGB color mode. if it is need - to make overlay layers with multiply or softlight or others. with opacity. if it is necessary - auto tone or colour Link to comment
Cadmium Posted May 10, 2019 Share Posted May 10, 2019 I don't know how to do that processing. :(Your flower/building pic is very nice! What building is that? Are those both clocks, or is one a speedometer? Link to comment
Andy Perrin Posted May 10, 2019 Share Posted May 10, 2019 These are all fantastic images, ins13. I love the flowers and the little kid on the railing[*] best. [*] How was he allowed to do that?! Was it less dangerous than it looked? Link to comment
ins13 Posted May 10, 2019 Author Share Posted May 10, 2019 Cadmium, thanks!) Why do not know ? lab colour in photoshop? I'll write in greater detail later once I've determined the best options.It's a University building. These are a clock, barometer and thermometer. not speedometer :) Andy Perrin, thank you very much!!! :) it's less dangerous than it looks. There is large but smooth downhill just behind the railing . to fall and slide down is possible of course but unlikely big damages some more pictures Link to comment
Cadmium Posted May 10, 2019 Share Posted May 10, 2019 Yep, you know how to process. Those are great, probably some of the best I have seen using #12.Yellow tail lights... love them. Yellow botinki! (Evgeniya taught me that word) I think I am using that word correctly...?The fog actually works very nice with these. Link to comment
ins13 Posted May 10, 2019 Author Share Posted May 10, 2019 Thank you for the kind words!!))yes, yellow botinki :DI completely agree: in foggy and non-Sunny weather the orange filter works perfectly. I like it less with the sun Link to comment
JMC Posted May 10, 2019 Share Posted May 10, 2019 These are really nice images, and yes with the foggy weather it works really well. Link to comment
Cadmium Posted May 10, 2019 Share Posted May 10, 2019 Is the street sign blue in visual? Link to comment
Cadmium Posted May 11, 2019 Share Posted May 11, 2019 OK, it didn't make sense at first, but the visually blue paint must reflect IR, therefore it is red. Link to comment
Cadmium Posted May 11, 2019 Share Posted May 11, 2019 Take a pic of the same sign in 850nm IR and the blue should look white. Link to comment
GaryR Posted May 12, 2019 Share Posted May 12, 2019 Eka,Outstanding Aerochrome processing on these images! The first one is great just on the subject matter alone, but colors of the crowds of people is quite intriguing. I had to look up the OC12 orange filter, and see that it's quite a bit darker that the standard #12 yellow, which is normally used for this kind of processing. Link to comment
ins13 Posted May 12, 2019 Author Share Posted May 12, 2019 Cadmium, the red colour of the street signs is a result of channel mixer GaryR, thank you very much! :) But probably it's not just the differences between the different orange filters. I checked orange ОС11 filter and yellow filter ЖС18. Results are similar. I don't know, probably, nobody paid attention that I use for these images the IR-blocked glass СЗС14 - like СЗС24. I wrote about it at first post. It works very well for imitating infrared film. The main thing is to choose the right degree of cut-off of the infrared. For example сзс25 is too much cut-offHere are the comparisons OC12 and OC12+СЗС14the processing of both images is exactly the same OC12 OC12+СЗС14 Link to comment
Cadmium Posted May 12, 2019 Share Posted May 12, 2019 Yes, the red color of the sign is a result of channel mixing using the 550nm longpass filter, but what I am saying is that the sign is blue visually, thus the channel swapped red represents IR. In other words, the blue paint of the sign reflects strong IR.It is not important, it just had me curious where the red was coming from with the blue and white sign, it comes from the IR in the paint, visual blue disappears with minus blue filters.https://russiatrek20.../moscow2020.jpg Same street corner on Google street-view:https://www.google.c...!7i13312!8i6656 Link to comment
Cadmium Posted May 12, 2019 Share Posted May 12, 2019 Very nice photos above also. :-) Link to comment
Cadmium Posted May 12, 2019 Share Posted May 12, 2019 The OC12 is equivalent to Schott OG550. Both have slightly steeper transmission slops than the Tiffen #12 filter.OC12 and OG550 work virtually as well for this as does #12, in my opinion.Here are some graphs below. The red line is OG550 2mm thick. 3mm would be even closer. OG550 3mm thick: Link to comment
ins13 Posted May 12, 2019 Author Share Posted May 12, 2019 Thank you) and thank you very much for the graphs!! Graphs is my everlasting gap :) Link to comment
Cadmium Posted May 12, 2019 Share Posted May 12, 2019 Stack your OC12 with S8612 or such, cut off the 700nm+ IR, and see what happens to the blue. Link to comment
Cadmium Posted May 12, 2019 Share Posted May 12, 2019 The blue sign turns red.The color checker card blue turns red.The blue house turns red. This is not because of the visual color blue, it is because of the IR.If you block IR with a #12 (550nm) + Visual only bnandpas filter stack, then the visual blue should turn black, using the exact same post processing.

ins13 Posted May 12, 2019 Author Share Posted May 12, 2019 Yes, the color of the blue street signs turned black with more strong ir-blocking filterI apologize for the poor quality of the pictures. these signs were far from me. nothing closer. And, of course, it is not blue visible, I understand it, because the orange filter does not pass blue Link to comment
Ninjin Posted May 12, 2019 Share Posted May 12, 2019 Very interesting photos and combination of filters! Does adding of IR Block a bit brighter 'yellow' color (after processing) than using only ОС12?It seems the color of yellow is much better. Not so greenish. Link to comment
