Tintypes are also reversed, but that's a part of their charm. And this paper, while certainly pricey at present (import VAT being a killer) is nonetheless usefully faster than any other. I think it will find its niche.
Yes, it's speed was why I backed their first KS campaign. And, I will probably back this one for 5 rolls. When I commented on the high prices it was in regard to contact printing this paper when it is used as a negative. You just use regular paper to print, you don't have to use the expensive high speed paper to make the positives. When I use this material I'd only use it to make negatives thus saving it for what it does well. My original interest in paper negatives is fueled by two things, low cost and you can work under safelight. The down side has been the very slow speed of regular paper, ISO 3 to 6 usually. The high speed of this paper solves that problem but at more than double the price of a roll of HP4 so, win and lose you might say.
As to the reversed image on DP paper, well it is probably a personal issue that bothers some people and not others. As to Tintypes? Well with that process you don't have a choice, the medium is not translucent. Even with a positive only image like a tintype, they were sometimes displayed in a fold open picture frame where one side was a mirror. Thus you could view the image as a reflection with the correction orientation.
Paper negatives seem popular enough that I've always wondered why no one ever made a paper specifically for that purpose. The paper would be designed for low contrast and a somewhat faster speed. Even ISO 25 or 50 would be a big help. Here in the US I can buy Ilford 120 in either HP4 or HP5 for $5 a roll currently. I don't know what the price is in the UK but so far our prices seem reasonable for B&W film.
