Yellow/Green Filter and Development Time.

[Gary Grenell]

Today I made a photo of a gentleman against foliage. I used a #060 yellow/green filter and was shooting with Plus X rated at 80. Normally, I would pull the development on this scene by one stop, to prevent the highlights from blocking up (it was late afternoon, direct unfiltered sun and the leaves looked pretty bright in the sunlight). I did increase my exposure by two stops when making the photo, as the filter factor is 2 for this filter.

My question is, how does the use of this filter affect my development time? If, unfiltered, I would pull 1 stop, does this remain the same or change with the #060 filter?

Thanks in advance.:confused:

You compensated for the filter factor, so develop as you always do.

Yeah. An on-camera filter affects exposure when you adjust your exposure. The only need fo adjusting processing times would be if the filter factor adjustment were to lead to reciprocity failure.

I think I see where the OP is coming from.

He has yellow sun, and yellow/green foliage, and a yellow/green filter.

There is a danger that he might have a fairly compressed range of subject brightnesses recorded on the film.

I would consider increasing my developing time or, in his case, doing away with the indicated pull.

Your leaf highlights in the sun are going to give you some points of white light regardless, if you are unsure of whether to increase or decrease development, always go with the lesser, it is easier to make contrast then to dilute it, id go with a wide range developer, not something like POTA but maybe something with stand development capabilities, rodinal? with slightly increased time. what the filter does is passess its own colors and blocks others that it is rated to , at the extent it is rated too, i think your filter may be comprable to the #11 wratten yellow/green, green foliage is not highly saturated green and will not increase in negative density with use of even a #61 deep green filter, the yellows probably didnt increase much, you should only worry if your using something like a #15 with a yellow flower, in which case no factor would be given as it readily passess the yellow and does not signifigantly lower other values (unless in a highly saturated landscape) the reason for giving a filter factor is to give more exposure to those colors which are blocked by the filter, which in turn increases hte passed exposure, therefore filter on lens exposure often deals with over exposure, but i think for your case you would be fine with the type of development i suggested

Thanks to all

Thanks to all for their input. Brought my film to the lab today (i don't enjoy processing film) and had them pull 1 stop (N minus 1), which would have been the instruction absent the green/yellow filter. I appreciate the expertise in these forums!
