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

Now these two images might not look like much but they are actually quite cool. They are direct positive prints straight out of the back of an 8x10 large format camera no contact prints, no enlarges, no negative, no inverting and in colour all I did was load some Fuji Crystal Archive Paper into a film holder and Processed it using this procedure these are two test shots from today I did several over all and learnt a few things.

1. As with most paper negatives (are these paper positives now?) You need A lot of light ISO I think is around 25 

2. Longer in the B&W dev gives you Blue cast and shorter Green 

3. The images are incredibly sharp

I never set out to get perfect picture with this so I wont be using an elaborate system of filters, chemicals, temperatures and timings. I think the top one looks a bit like a LOMO style cross process image and I like that, there is a lot of room in this process for some interesting one off images so will be experimenting a lot more with it hopefully to find a colour balance I like and then the aim is to do some portraits
