Hi,
Have you used the Neopan films Acros 100 and Neopan 400?
What EI do you set them to and how long do you develop them for!!
I shot a roll of 400 with a red filter on the lens on a misty day at the 400 setting!!
I developed it in Rodinol 1+25 but the pictures were very grey and grainy!!!

Hi,
I haven’t used Neopan 400 with Rodinal 1+25, but it used to be my standard film with Rodinal 1+50 – I rated the Neopan 400 at 250 and developed it in Rodinal 1+50 at 20°C, with 30 seconds of constant inversions, followed by two inversions at the start of every minute, for a total of 9 minutes.
How did you measure – through the filter with your camera, or with a handheld light meter? It is not a very good idea to measure through a red filter, as the red-light sensitivity of many camera-integrated meters does not correspond to that of black-and-white film – it is better to use a handheld meter or measure without the filter in place first, then apply the correction factor for the red filter (depending on how dark the red is, the factor is usually around 8x – meaning you have to open up the aperture by 3 stops).
What effect were you trying to achieve with the red filter in the first place?

Well, to tell you the truth, I don’t know why I put the red filter on – just to see what effect it would have, I suppose, as I’m new to this business!!!
I have a Dynax 5, so I just adjusted the exposure compensation using the dial
on the camera so that it read ZERO on the display inside the camera!!!
Are you the same bloke with a negative image of yourself on the board!!!!

Nah, that's just a 'special friend' of mine, who thinks he's being funny...

Oh, I see!!! Am I supposed to laugh now?? Just tell me when I’m supposed to laugh!!!
What does a red filter actually do!!

Obviously, a red filter is pretty much useless when shooting black and white!! :angry: Try using it with colour film!!! :) You’ll be amazed!!!! :D
Niall
I think someone told me it was suitable for black and white!!
OK! Ferdinand OR Roman (You need to get out more!!!)
What does it do for colour film!!!!!
Niall :angry:
Roman
Hi Niall,
Ferdinand’s pulling your leg! The red filter doesn’t do anything useful for colour photos – everything will just turn red...
In black and white, the red filter is used:
-) for infrared film (such as Kodak HIE) to block out visible light and only allow the red end of the spectrum to pass through – producing the typical ghostly IR images, with glowing white foliage (‘Wood effect’) and dark skies.
-) for standard black-and-white film: to boost contrast and darken the sky, to achieve a sort of ‘moonlight’ effect, resulting in very artificial-looking images, with a graphic quality.
I don’t find it very useful for landscape photography, as a red filter not only darkens blue (the sky) but also green (foliage), which results in very poor shadow definition. Personally, I don’t like the red filter at all; it might be useful for photographing (modern) architecture, producing somewhat abstract, artificial, graphic results.
For me, the most useful filter for landscape photography, but also for portraits and general photography, is the yellow-green filter: it slightly darkens the blue sky, giving better definition to the clouds, and it slightly lightens the foliage, making it look more defined; the most extreme filter I use is the orange one, which is sort of halfway between yellow and red – higher contrast, but not too artificial-looking...
