Hi,

Have you used the Neopan films Acros 100 and Neopan 400!!

What EI do you rate them at and how long do you develpo them for!!

I shot a roll of 400 with a red filter on the lens on a misty dayat the 400 rate!!

I developed in Rodinol 1+25 but the pictures were very grey and grainy!!!

Hi,

I have not used NP400 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 in Rodinal 1+50, 20?C, 30Sek. constant inversions, then 2 inversions at the beginning of every minute, for 9 minutes.

How did you measure - through the filter with your camera, or qith a hand-held lightmeter? It is not a very good idea to measure through a red filter, as a lot of camera-integrated meters' red-light sensitivity does not correspond to that of B&W film - better use a hand-held meter or meter without the filter in place first, then dial in 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 3 stops).

What effect did you want 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 give,I suppose, being new to this bussiness!!!

I have a dynax 5 so I just adjusted the compensation with the Dial

on the camera so it read ZERO on the display inside the camera!!!

Are you the same fella with a negative image of your self on the board!!!!

Hi Niall,



Ferdinand is pulling your leg! The red filter does not do anything useful for color pictures - everything will be tinted red...

In B&W, the red filter is used:

-) for infrared film (like Kodak HIE) to shut out visible light and only let pass the red end of the spectrum - giving the typical ghostly IR-pics, with glowing white foliage ('Wood effect') and dark skies.

-) for regular B&W film: to boost contrast and darken the sky, to achieve a kind of 'moonlight' effect, to get very artificial looking pictures, kind graphic looking.

I don't find it very useful for landscape work, as a red filter not only darkens blue (sky) but also green (foliage), which will give very bad shadow definition. I personally don't like the red filter at all, it might be useful for shooting (modern) architecture, giving kind of abstract, artificial, graphic results.

For me, the most useful filter for landscape, but also for portraits & general photography is the yellow-green filter: it will darken the blue sky slightly, giving better definition to clouds, and it will slightly lighten foliage, and make it look better defined; the most extreme filter I use is the orange one, which is kinda half way between yellow and red - higher contrast, but not too artificial looking...
