First, much thanks Pekka for your LS_D60. Excellent tool! The workflow for these images after acquiring a linear tiff was to apply the convert/medium sharp setting (w/Beta_2), followed by PS_7 autolevels, then two hits with noise blur. Generally I’m pleased with the results but before I compose final images, any suggestions from the forum on my Moiré problem? It shows up pretty notably in the whiskers of the male tiger?

(Warning dialers – I need to reduce resolution; file sizes are 250k)
For those interested both frames were taken as follows:
D60: Canon 70-200mm 2.8 IS (ISO 200: 105mm f3.5 and 200mm f3.5 respectively).

Have you cropped and enlarged your images? There are too much jaggies. At this point it is very difficult to rectify them. Few things might have caused it
1) Too much sharpening
2) Too much cropping and enlarging
3) D60 cmos can create such pattern and color artifacts for very thin and closely spaced lines and grids.
I will suggest use the 100-200 HQ chooser option in Pekkas Linear Sharpen. i do not use it much so I can not remember, but so far I can remember- post conversion if you look into the history palette, you will find Pekka has already created all different levels of sharpened images. Very neat! Press Ctrl + Alt and 0 to zoom up to 1:1 size and select the image which looks the best.
Auto Level is not always good. Learn how to manipulate levels and color. This the one of the most important basic digital darkroom technique for any digital photographer. It will pay its dividend in the long run.
Lastly have you ever tried Ultrasharpen (http://http://www.ultrasharpen.com) ? Download the lite version; it is free. Much easier to use than Unsharp Mask for a Photoshop newbie.
Sorry, if I have used too many technical jargons. I am trying to help and not to confuse anyone. Earlier I was rebuked for my response :D Being a Software engineer, I sometime inadvertently become nerdy. Advance apology.
