[Leica] Re: Curved edges

[Jim Brick <jim_brick@agilent.com>]

Mary,

Which lines are not straight? Lines IN the print (telephone poles, building 
sides, windows, etc.) or the edge of the print where there is a white 
border crreated by the easel blades or easel border that holds the paper 
down during exposure?

What kind of easel are you using?

I cannot believe it would be IN the print as that would not have changed 
and would actually be flatter/straighter in the glass carrier.

If it is the edge of your print, your glassLESS neg carrier is not full 
frame and you are probably using the easel to create a border on your 
prints. Easels make straight lines. If you are printing inside the easel 
with the glassLESS carrier, the carrier edges are machined straight and you 
will get straight border lines.

With your new glassless carrier, you are probably printing the entire 
negative including the space around the film, giving you a black line 
around your print followed by the white border from the easel. Is this 
correct? If so, it is your negative edges that are causing the non straight 
lines since you are printing the edges as well as the image itself.

Bottom line, going from a glassless to a glass carrier will have no effect 
on the image lines except that the glass carrier will give a flatter 
straighter representation of the image (but watch out for newton rings and 
dust.) The edge of your print is controlled by the edge of the neg carrier 
and the easel blades or edges (depending upon easel type.) And should be 
straight.

So look at the edges of your negative which you are now printing but were 
not printing before. And how they lines up with the blades of your easel.

I hope I read your question correctly...  :)

Jim
