Confused

[Digi-Steve]

Hello,

Last night I took 150pics of 15 sec looking like this

All together in DSS it looks like this

What goes wrong here. I'm confused. I saved the DSS result and put it into CS5 to edit but as soon as I play with it, banding shows up.

Any ideas.

I've been out a few times now and the end results are putting me off.

Star count looks very low on the DSS output, when you see the imput files showing plenty of data.

i would bump the star count in DSS see if that throws up a better result. you have well over 100 stars showing in the input image, so check DSS knows this bumping the star count up

[Digi-Steve]

The star count is set to 2% and it give a rate of +200 stars

Are you adjusting the luminance and RBG/K values to stretch out the curves in DSS before you save your TIF?

[Digi-Steve]

I'm not touching anything. I also notice that the end result i see in DSS has more stars then the saved picture. I'm very confused

[Digi-Steve]

This is the example of what I see in DSS as end result. Totally different then my Saved Tiff file.

I run DSS on a mac using VMware Fusion 4

I can't really shed any light on whats causing this, but I my preview of the end result in DSS is always dark!

I also do not have CS5 (I have CS2), for me I have to change the mode on the TIF from 32bit to 16bit. Then I adjust the levels, then play with the curves...

What are you adjusting in photoshop?

I adjust the levels as I've seen in tutorials. After that I play with curves.

My experience with DSS is that it saves the output as a 16bit TIF (as well as an Autostack.TIF).

When you open PS to manipulate the TIF from DSS, it should detect it's a 16 bit/pixel file. It's not opening it as an 8 bit/pixel file is it?

The file does look dark in PS, but the first thing I do is a histogram stretch to move the white point in (leftwards) to show up the details.

I've never used DSS so can't comment on what has happened but as I see you have CS5 you should have no problem with getting a reasonable result from the original image.

I have CS3 working on a Mac and can pull out quite a bit from the first image............Might need to increase the saturation looking at the result on Forum screen.......
