a red filter would , besides being useless, not let the blue light pass
And I thought I was doing well

I shot through a 4x5 box about a decade ago and totally agree with INTERNEG that it seemed like regular film minus red sensitivity. It provided a little better tonal separation in tree leaves but I saw no sign of extraordinary sensitivity to blue or UV. Ilford provides a spectral sensitivity curve in the relevant data sheet: http://www.ilfordphoto.com/webfiles/...7119221450.pdf

A very good example of what today's ortho films will do. I use ortho film about 5:1 compared with panchromatic film.
Is Ortho Plus what you are shooting, or is there something else available in continuous tone today? I've been curious about the Ilford. I've got an old box of Tri-X Ortho that still seem fine. I'm shooting Xray film in 11x14, but I'm not sure how similar that look is.Originally Posted by Jim Noel
I am shooting the Ilford Ortho Plus ISO80. Not sure of the other ortho film from years back, not familiar.

I use both Ortho Plus ans X-ray film. They are very similar.
The most relevant factor is spectral response. An ortho film has the tonality of a regular panchromatic film shot with a deep cyan filter.
With ortho films a yellow filter has the same effect than a green filter, because allowing red to pass (yellow filter) has no effect. So using a Yellow or Green filter with ortho film deilvers same effect than using a green filter with panchro film.
Thanks. That is certainly interesting to hear. The spectral response does look similar in some specs I've seen. I'm still a little surprised sometimes the way some faces look on x-ray film. I tried to get an ortho look for a rephotographic project a number of years ago with filters, but kind of messed it up. I recently got a minus red filter which should be closer. I tried that yesterday for the first time. ortho film such a normal part of photography for so long, but kind of fringe information for a while now.
I have meant to try the Ortho Plus for a long time, but just haven't gotten around to it.
It's a great film for mid-late 20th Century Scottish municipal pebbledash - brings out the contrasts nicely. If your granite is anything like the Aberdeenshire granites, it might do a similar job tonally.
Other aspects of the film worth noting are: 1, it's slightly less hardened than other Ilford films, & is paper interleaved; and 2, the 'ortho'-ish-ness of it depends on how high a CI you take it to - at normal-ish CI's it can look more panchro-esque than you might expect.
