Rollei Orange filter compensation

[baachitraka]

The exposure compensation required for this filter is from -1.5 to -3.0 stops and may I know why is this range? Does it has anything to do with the light from the Sun at the raise, noon and at the set?

I use a orange filter (BW film) all the time on mine and shoot as per light meter. Turns out perfect. ND filter is different story.

Depends on different film sensitivities to the color spectrum. As Todd mentions the latitude of most B&W should produce a printable negative whether you compensate or not however knowing you're using such a filter it does not hurt to shoot one stop or so open from a standard meter reading for the film's speed. Personally for higher contrast scenes I'd do 1.5-2 stops open and pull back slightly on development time, for standard or low contrast lighting only 1 stop and no development time change.

I like the orange Rollei filter and use it a lot. I always give it 2 stops. My use of it is generally always for the same reason, to darken the blue sky. I guess if you are shooting autumn leaves with lots of red and orange color you might not have to give it so much.

I use incident meter together with Rolleicord.

I use an orange filter a lot, both a B1 on my rolleis or a orange on my other cameras, I simply set my Weston V to 100 for a 400 film giving me 2 stops extra exposure and follow the meters exposure readings, works every time, for different speed film simply set the meter 2 extra stops, saves a lot of working out

 

[JPD]

I too give it 2 stops with panchromatic film, and 2,5 - 3 stops with orthopanchromatic films like Efke that are less sensitive to reds.

That's the way I use my Orange filter (B+W 040 4x).

I went through this myself, and strangely enough, different filter makers give different answers to that question. Basically, I had to shoot a few frames to figure out what my film, w/ my camera, w/ my meter worked best. 1.5 stops difference w/ B&W film is not that much anyway. In the end I discovered that it was a lousy filter for dark complexions, and gave it up. It turned the wife into me! (one of use is dark, the other light).

I'm a red and yellow filter guy all the way, at least this point.

Try bracketing some different exposures using 1.2, 2 and 3 stops and make up your own mind which you prefer with your film.

I was curious about the compensation range for this filter and as well as the light-red filter.

I thought it may be due to different spectral during day and as well as during morning and evening.

That is true as well, and the colour temperature also affects the film speed a little.

For the sake of completeness ... - sometimes I use a green filter (B+W yellow-green 060) for portrait photographs : +1 stop

Good guide.

At the end it will depend on:

1) The amount of yellow/orange-ness of your subject. If you're under tungsten lights, you don't need to compensate so much.

and

2) The spectral sensitivity of the film. For example Foma 400 will be very different to Tri-X.

It's simply becausefilter compensation depens on subject color.Take a few test shots of a typical subject for you and bracket in 1 stop increments. this will tell you the optimum compensation for you.

That never works for me. the spectral sensitivity of lightmeters ary and they can get easily fooled by colored filters.

I'm confused with this. My Yellow and Green filters says 1.5 and Orange 1.5-3.

Looking at the ND filters chart, 1.5 density is 5 stops and 3.0 density is 10 stops.

I know it's not the same as ND because ND with density of 3.0 has almost completely black glass, but what's this measure then on color filters? It's confusing because it has the same numbers but the conversion is stops is totally different.

 

[Dan Daniel]

Color filter numbers are stops of compensation. So 1-1/2 stop more exposure for the Yellow and Green.

Always best to do tests on your actual filters and film stock combos.

Thanks Dan, it's clear now. I never used color filters, so I'll certainly have to test them asap.

At the same time, I found 1.8 and 3.0 ND filters in a dusty box, that I never used and wanted to give i a try, and I was a bit confused, why it has the same numbers and the compensation in stops is different. But now I get it.

I have this table in my notes, but without the transmittance column. Now it's completed! Thanks.

No. On Rollei filters, the numbers are "Light value compensation." The easiest way to think of it is as a multiplying factor for the shutter speed. The first number is for Ortho film, the second for panchromatic. For example, medium yellow is 1.5× for Pan film. So that means about 1.5 times the exposure or about a half stop.

But do test your favorite film, developing technique, and your light meter.

-1.5 = A half stop for Orange?

-1 = No compensation for light yellow and light green?

 

[Kodachromeguy]

It's confusing. I spent a lot of time trying to understand these numbers decades ago. I usually use the f-stops that mnemosyne recommended:

yellow +1 stop
orange + 2 stops
red + 3 stops
