Old Ford, New Specs

Just out of curiosity here, Ken, what are the two principal colours here. Is it yellow(bonnet and radiator ) and red( engine and gearbox) and any filter used Thanks

@pentaxuser Yes, the bonnet and radiator are yellow, and the block/gearbox is red. I wasn't using a filter. The day was dull and gray, as you might have surmised from the exposure; I took the photo in the early afternoon, too.

Thanks Ken I find it useful to study such shots knowing the true colours so that I can think "b&w" colours more clearly. I had initially wondered if maybe an orange or even red filter had been used as the yellow looked almost cream coloured and I tend to think of the colour yellow as deeper than this in b&w without a filter but then realised that while a red would lighten yellow it would have had more of a lightening effect on the engine/gearbox as well.
Works well in b&w

Interesting ideas. I tinkered with the contrast a bit, by the way, trying for a pleasing balance between the block and the hood (bonnet!) before settling on this version. I just got a yellow filter the other day, but it's for other lenses. Otherwise, I might have tried it.

Yes the problem with a yellow filter as i understand filters is that if the two colours are yellow and red then even a yellow might reduce contrast and orange or red certainly would. So a b&w picture of a soccer team in tops of red and yellow stripes might require a bit of thought if you wanted to increase contrast. Possibly a yellow/green filter might work but I don't know. Maybe no filter would work as well or even better as in this picture rather using any filter at all

Nice! Those were very common when I was a kid, except they were in the original light gray and red. Great you're developing your film. Next thing is to do real prints. I know you probably need some equipment and a set-up for than, but, it's really rewarding.

@bsdunek I've got a "photo-pal" here in town who keeps threatening to let me use his enlarger and such, but I'm also considering getting a mid-range inkjet printer. Sending my stuff off to Costco when I want a print is getting a bit tiring . . . Hey, and thanks for the comment!
