ins13 Posted April 6, 2019 Share Posted April 6, 2019 I like the orange filter. I saw a lot of photos with an orange filter and took a lot of such photos myself. I like them all.It will not be a mistake to say that when processing these photos, usually the replacement of channels is done.As a result, the blue trees and grass become reddish tone processing: cheater slider "hue" instead of replacing the channels :) + color saturation, contrast But!The effect obtained without replacing the channels is as good as with replacement. In my opinion. Green trees and grass continue to be blue. Autumn leaves remain yellow.However, this method of processing apparently has limitations. On the open space when shooting landscapes the images turn out not very appealing. with rare exceptions perhaps. But under the forest canopy colors are very nice, fabulous even. in my opinion again Link to comment
Andy Perrin Posted April 7, 2019 Share Posted April 7, 2019 Oooh. That snake looks very scary. I like your enchanted woods! Link to comment
ins13 Posted April 7, 2019 Author Share Posted April 7, 2019 Thank you very much!! :)It is a natrix. a harmless snake. It was so frightened and have pretended to be dead, even opened their mouth for naturalness and didn't move, and lay so until I go away. Link to comment
Andy Perrin Posted April 7, 2019 Share Posted April 7, 2019 Heehee, "opened their mouth for naturalness." Link to comment
ins13 Posted April 7, 2019 Author Share Posted April 7, 2019 :D By the way yellow spots on the belly of the snake remained yellow. In the same way, the yellow autumn leaves have retained a yellow color. Green leaves, moss and grass turned blue. Link to comment
cancington42 Posted April 8, 2019 Share Posted April 8, 2019 beautiful images!! when you say orange filter, is it a specific infrared filter, or is this just the colour orange? like a basic gel coloured filter? Link to comment
ins13 Posted April 9, 2019 Author Share Posted April 9, 2019 Thank you very much!! :) It's a glass filter, russian ОС12, or other its designation O-2.8 x Link to comment
nfoto Posted April 9, 2019 Share Posted April 9, 2019 Orange filters typically allow deep orange, red, and infrared to pass. It is a strongly orange in appearance. The Nikon designation is O-56. Wratten 18 equivalent if memory serves. Link to comment
Cadmium Posted April 9, 2019 Share Posted April 9, 2019 Birna, 81, I think you mean.AKA Schott OG550, 550nm Longpass. Link to comment
ins13 Posted April 9, 2019 Author Share Posted April 9, 2019 It is the most usual orange filter isn't it? average :) Link to comment
Cadmium Posted April 9, 2019 Share Posted April 9, 2019 Usual? I don't know. I think 550nm is popular yes.I think they call 590nm the "Goldie" look, not sure.Here is a 570nm shot, swapped (Schott OG570). Link to comment
ins13 Posted April 9, 2019 Author Share Posted April 9, 2019 Yes i imply usual as a popular. My English....It seems to me 570 is better than 550 in swapped version Link to comment
Cadmium Posted April 9, 2019 Share Posted April 9, 2019 I think 550nm is better. So is sunshine... Link to comment
dabateman Posted April 9, 2019 Share Posted April 9, 2019 Birna,The Wratten equivalent to a 550nm is the #16. I also like the Orange wratten #22. The 590nm wratten equivalent is a #25. Link to comment
nfoto Posted April 10, 2019 Share Posted April 10, 2019 If I ever doubted -- memory is failing :) or expressing laziness as I didn't bother to pull the Kodak filter handbook of filters from the shelf to check :D Oh well -- found and consulting the old handbook now and the Nikon O-56 obviously is #22 not #16. Wratten #18a, #18b are for UV [with film]. #25 is Nikon R60, which is a red filter. In the former days of the IE (Infrared Ektachrome) I didn't like the effects of the R60 as the sky turned green not blue. Link to comment
Cadmium Posted April 10, 2019 Share Posted April 10, 2019 There are the Wratten 81A, B, C, D, and EF, which are all pale orange, so I thought maybe you just had it typed backwards, but those are just 'pale'... not the same.25 and 29 are 580/590 and 600/610, depending on what info you look at. Schott OG590 and RG610.And then there is 25A, not sure how that is different, or not. I have the books too, but for handy reference (not all Wratten filters listed in the books are on this list, books from different years include or exclude various filter numbers):https://en.wikipedia.org/wiki/Wratten_number Link to comment
ulf Posted April 10, 2019 Share Posted April 10, 2019 The B+W Yellow-Orange Filter 040 (16) is also OG 550 More B+W filter information:https://www.dropbox....ndbook.pdf?dl=0This document is not available anymore on the net. Link to comment
dabateman Posted April 10, 2019 Share Posted April 10, 2019 Ulf,You correct, the new BW catalog is only a brochure, with less filters. https://www.schneideroptics.com/Ecommerce/CatalogSubCategoryDisplay.aspx?CID=57 Glad I downloaded the earlier version. I am not sure why, but I seem to think in Wratten numbers. Probably, because the old reference books are all free downloads. The common yellow filters were #8 (50% 495nm), #12 (50% 520nm), #15 (50% 530nm)The #3 seems to have made a come back as I see it available new, 50% 455nm.The Orange were #16 (50% 550nm), #21, #22 The reds are #23A less common, #24 (585nm), #25 (590nm), #29 (630nm), #70 (680nm) The Wratten book:https://archive.org/details/WrattenLightFilters/page/n21 Link to comment
Cadmium Posted April 10, 2019 Share Posted April 10, 2019 B+W 040 and 099 are the same, both made of Schott OG550 filter glass.The difference (according to the B+W catalogue I have) is that the 040 is available with coatings, whereas the 099 is not. Larger filters not shown on this chart width are the same. Link to comment
