Thanks Ric and Jase, I will have another go at processing this one, but I'm not quite sure what to do, or how not to do the clipping stuff you have mentioned.
I usually convert to tiff's as normal, then open in Image Plus, align and combine with average, an end up with a combined image, then i use digital development and move the background white to 65-70, and then move the break point to where the image appears the best.
Sometimes i then take it to PS2 and use levels on it to see if i can enhance it some more, usually that's about it.
Am i doing this wrong, as I not sure if this is the best way and what should the Histogram look like.
Thank You.
Leon
