3X is the filter factor, which makes no difference if you use TTL
metering......

I use a hand held meter, and I meter through the filter.  Same as above.

I do, however. Chjeck this meter reading versus without the filter + filter
factor.  If there is a difference, I split the difference ... I take 2
images.  One each way.

Film is cheap, missing a shot because I am too cheap is unacceptable.

Back to Dark Yellow:

According to ilford's website, "A typical yellow filter will have a 
filter factor of 2; the manufacturer will supply the exact factor with 
the filter. Most cameras with TTL metering will correct automatically 
for the filter factor but check the camera instruction book".

OK.  i get it.

But on the box, the label states "Dark Yellow 3X Coated".

My question is:  even though the R8 and R9 read through the lens, do I 
want to open up a stop or two, or go with the internal meter reading 
and just shoot away?
