This is weird! Why're customers of DR5 reporting to Fotompex the problems they face with DR5 processing?! They should report the problems to DR5 and additionally make the problems known through forums such as this.
They have of course contacted them. But the response was not satisfying. And using a forum is unattractive for probably 99.9% of film photographers. That is at least our assessment if we compare the number of total Fotoimpex customers to their activity in forums.
Anyway, can you share with us the problems DR5 customers have reported to Fotoimpex?
We will send you a conversation.
Hey! these data sheet values, DMax and DMin, are not in your datasheet ;-P and it's a pity that I had to get them from you through this thread!
As already explained, these values differ from process to process. And they also in addition differ because of variances in processes done by photographers by themselves at home, e.g. variations in first development time due to personal preferences. Therefore it doesn't make much sense to implement them in a film data sheet.
Now if you claim that your process gives overall better overall quality than DR5 and other processes
Sorry, but we have not claimed that at all. We've just explained that Dmin and Dmax should not be overrated, and that the image quality is dependent on a combination of several different factors.
Maybe this short example makes the point more clear: You will not see a visible difference in projection between a slide with 3.1 Dmax in comparison to a slide with 3.3 Dmax.
But you will see a significant difference between these two slides when you project one with a cheap projection lens, and the other one with a better quality lens.
And you will see a significant difference if you view one through a cheap loupe an a lighttable, and the other one with an excellent loupe.
There are factors much more important than density values.
