Stealth3kpl Posted May 29, 2012 Share #1 Posted May 29, 2012 Advertisement (gone after registration) I thought I'd compare results with yellow, orange, and green filters. Well,....I can't tell any difference. Where did I go wrong (or can you tell a difference?)? Pete Yellow: Welcome, dear visitor!

too old to care Posted May 29, 2012 Share #3 Posted May 29, 2012 My guess, your scanner is "correcting" the image, trying to make them uniform with a program installed at the factory. I use yellow and red for almost all of my shots outside. I certain can tell the difference, although I do not scan my negatives for printing, I still use chemicals. Do the negatives look different to your eye? There should be differences in the contrast between them, it should be apparent. This is especially true for the orange and green filters.

madNbad Posted May 29, 2012 Share #4 Posted May 29, 2012 Either have prints made from the negatives or just try a contact sheet. TOTC may have hit the mark with your scanner adjusting the image. On paper the filter effects should be obvious. Link to post Share on other sites More sharing options...

earleygallery Posted May 30, 2012 Share #7 Posted May 30, 2012 Advertisement (gone after registration) I agree, there's something at play here to do with scanning or post processing, because the photos would look different, especially with the green filter.

Leicanerd Posted May 30, 2012 Share #8 Posted May 30, 2012 The irony is that just the green filter caused the darkest shades of green. What is the reason? All three examples are aligned in terms of exposure to the best representation of the white clouds and the blue sky. As a green filter has the weakest blue damping, one has to make a darker enlargement than necessary when using an orange filter. This of course affects the overall impression of the image, and the foliage is even darker than when using an orange filter. I recommend the use of a deep yellow filter (Wratten #15, available from Heliopan). It provides almost as good tonality of sky and clouds as an orange filter with the advantage that it does not affect the greens, if that is to be feared.

No. They all appear the same What film did you shoot?Fgcm It's Fuji Acros (Legacy Pro 100) I really don't know what to think Pete Link to post Share on other sites More sharing options...
AlanG Posted May 30, 2012 Share #10 Posted May 30, 2012 Was the original scene in monochrome or full color? Seriously, how green was the foliage and how blue was the sky? Orange, yellow, and green filters would all keep the foliage from going real dark. And if the sky is not very blue, that might explain the lack of a major difference. If you do this again, insert a grey card and also shoot one without any filter. Then make sure when scanning that the grey card is reproduced the same in each. It does seem peculiar to me that there would be so little difference but as I said, the subject colors may be the reason. It does make me wonder about all of the concern about the MM's spectral response. Link to post Share on other sites More sharing options...

The lawn is quite bright green, the tree darkish green, and the brighter looking bush at the edge of the lawn is quite a bright yellow/green. I'm not sure if this is of use, taken with a ND filter: Welcome, dear visitor!

Fgcm Posted May 30, 2012 Share #13 Posted May 30, 2012 Interesting problem. I will test some different films with red and yellow filters and I will post the result. I have been a "beliver" of filters but I must say I never made a test. Fgcm Link to post Share on other sites More sharing options...
too old to care Posted May 31, 2012 Share #14 Posted May 31, 2012 I do not own an orange or green filter, but I though I would duplicate your experiment with no filter, a yellow filter, and a red filter. I shot this on Ilford FP4 at ISO 100 and developed in Rodinal 50 to 1 for 12 minutes. I then scanned them quickly on my Canon 8800F scanner with no care for dust, scratches, etc. However, the examples shows the differences between using even a yellow or red filter vs no filter. It is bright afternoon sun, no clouds, blue sky. First photo, no filter, 1/500 of a second at f11. Second photo, yellow filter, 1/500 of a second at f8 (to compensate for the filter factor) Third photo, red filter, 1/500 of a second with lens set 1/2 way between f4 and f.6 (again, filter factor) No compensation was done in photoshop and the scanner was set to manual, thus you see what the negatives look like. I do not know why your results are different than mine. But, you can see the differences the filters make in the sky. Forgot to mention, camera was my Hasselblad 501C with 80mm lens. Also, note the graduations in the sky due to the not so good Canon scanner. This is why I wet print my stuff for my own use. Wayne Welcome, dear visitor!

01af Posted May 31, 2012 Share #19 Posted May 31, 2012 Why don't mine work? :confused: Sorry, no idea. But from studying textbooks about b/w photography as well as from my own experience in both analog and digital b/w photography I am 100 % sure your result is the exception, not the norm.
