So, if Era RC paper is not available, what would beginer use in China? There is another one: Lucky ("乐凯"). Lucky produces 135 and 120 film. I would say that they have different characters to Era. Some people say that for sunny days, use Era; cloudy days, use Lucky. My personal feeling to them is that Era is like Trix, Lucky is like Tmax.
Lucky also produces fixed RC paper, usually 2# or 3#. But it's not my piece of cake: they are not pure black, and the contrast is a little lower. Maybe it's good for describing foggy nature scenes, though I haven't tried, since mostly I shoot portrait.
Nowadays, I start to use Ilford RC multi-grade paper. Though it is expensive, I could easily get the contrast I want by split-grading.
My hope to Chinese manufacturers is that they shall open their eyes further to the future, they shall not give up the traditional darkroom market. China is entering the preliminary developing stage, in upcoming years, more and more mature guys would turn back to traditional B&W, which has the beauty that no digital could express. That's why I seldom use digital camera now.
China is a large market, Ilford now takes almost all seats of fiber-base market & multi-contrast RC market. The price of Ilford is higher and higher, I hope more and more foreign producers of multi-contrast papers come here, they would not loose money here in the long term.
By the way, 2nd-hand darkroom enlargers are cheap on ebay in USA, UK, Germany, etc. Sellers of Durst, Kaiser, Beselor, LPL shall sell their enlargers to China, they would make a good fortune through ebay.
