I already have a Pentax Y2 yellow filter, like this one:
And I see the changes in my exposures when using the filter,
Now, I found a Orange X2 filter in my city, and I wanted to know, is there any real difference between yellow and orange filters?
I know there is a big gap from a yellow x2 filter to a x4 red filter, but I don't have experience with orange.
I sometimes use tmax100 but monstly Pan100 and 400 (rarely push it more than 1 stop).
The filter I found for sale is Cozo "Y2" (I think the seller must have got that wrong" filter
Any help will be much appreciated.
