This shot was taken yesterday continuing my mucking about with the RA4 Reversal Process, i pulled the dark slide out a little bit more each time to see how different exposures effected a filter combo that I liked. I would say im happy with the middle strip, you cant see it in this shitty scan but there are greens in there! finally GREEN! also seems to be infrared trees? anyone got any ideas about that?

well worth a watch, saw this on Mark Hiltons Blog which is also well worth checking out.

Some more experiments from today, didn’t go so well these ones. I used some of the filters I bought this week but think I need to go much more extreme with them, maybe if the second picture wasn’t quite as over exposed it would have been ok. will try again tomorrow.

The video shows the magic moment when the negative becomes a positive

Game changer, will post some results soon

This is great! seems like a really nice bloke as well makes me want to get some 20x24 and build something big 

These two shots are from further playing about with using paper colour negatives and ‘reversal processing’ them so they come out as positives. Colour balance is a huge problem with doing this with the first picture looking like a cyanotype! It is however really satisfying to get a big positive one off print straight out of the camera! 

Bottom two pictures show how the images look after processing in black and white developer and second image is how they look after being exposed to light and processed in RA4 developer and Blix

I will have to make a video of the image turning from black and white to colour
