RE: [APML] first try
Len,
It helps APML members assess images if detailed exposure data is posted on
the image web page. You can use the notes I have on my web pages as a
template. The more info you provide the better each viewer will be able to
provide you some insight. For example, Chris is asking about film type for
good reason. For example, different films render colors differently.
I think the image is stretched a bit much. It looks clipped on the top end.
My curving article goes into detail on that.
When you stretch so much, it increases the grain. Maybe SGBNR can help.
I agree with Chris' suggestion to use minimum to help reduce star sizes.
Star shaping would help too, but that's pretty advanced processing.
One reason I went to medium format (in conjunction with longer focal
length) was to get smaller stars.
