Film sales are going down. That's why plants are closed.
Over the last years there was a mean worldwide decline of about 30% per year.
On some segments the decline was less worse than on others, but the former were often segments that were already low in sales.
People who speak about uprise, have it about a niche within a niche. Or the cancelling of production at a competitor will bring short time relief for the other.
A further problem here at Apug is that constantly apples are compared to oranges. The photochemical industry is more than Agfapan or T-max.
Concerning Charts:
Even those companies who are obliged to publish figures can hide segments of their revenues within other segments. So be careful with these.
The most known charts are those of consumer film. But these only apply to certain major markets, do not take into all materials and all supply routes. So these have to be taken with care.
But you could still use your eyes: what do you see on street, in the hospital, in the print shop...?
But to my mind more important than charts is the current situation. Or with other words, what do manufacturers out of the situation? Try to consolidate the markets, or with written off plants fight for the lowest price?
