Well, at least one paper Dr. Ware recommends does seem to work. Unfortunately it's weird and being discontinued. Luckily it's HUGE sheets which will probably last me forever and was only 95p for elephantine-sized paper.
The thing you can't see from a scan is that this is like slightly shiny smooth tissue paper. It holds up to water well. However, when brushcoating, it likes to stick to the brush (!) on the final stroke closest to an edge so it's a bit of a fight to get it coated but the colour is good (better than what I've gotten out of Buxton paper and Crane's Kid Finish and Arches Aquaelle) I wasn't sure of its colour because it took a while to oxidize properly... some shadows look more solarised after washing. Oh it washes nicely too with it being so thin. I'm sure there's some artsy project you could do with Silversafe's see-through properties but I'm just not interested in that aspect.

First attempt with this lens. 2010-07-22. Sinar Norma with Homemade Petzval-type lens, Aviar doublet and +3 meniscus 220mm F/5.6 lens 1s at F/5.6, EV=9.5 at 100ISO. Kentmere VC Select at ISO6 in R09 1+80, 3-5mins at 20C. Invert colours, curves, spotting, The Gimp.
I've been trying to get the Petzval swirly bokeh in a homemade lens for a bit. Looks like I am close at last... more tests at the weekend.

August testing can be so tough! Summer vacations. Back to school time. There are a lot of distractions! So proud of all of our students who prepared and did their best at the August Belt Testing!

I wrote an article about the long term test. Please check here for German speakers: www.doreen.es/2009/07/04/test-der-grose-erfahrungsbericht...

One of the smaller-massive testing facilities at NASA Goddard in Greenbelt, MD.
When acoustics testing occurs, the entire area needs to be evacuated otherwise people will be injured, despite the 2' thick doors. Apparently this room can simulate the decibel level of lift-off.

Testing of the iPhone HDR option in the iOS 4.1 update. A summary of my observations thus far will shortly be posted to my blog.

There were two guys testing the water at Audubon Park. They told me they do this periodically. I wonder what were the results.
