@PPG;

I just had a look at "alienskin blow up" on their website....looks like a very interesting product.  I had heard of alienskin but had not heard that they produced up-resing software.  I will be looking into this product further.

The popular up-resing programs I have heard people use are Genuine Fractals and ACR itself.

Please tell us of your experiences using "blow up"....I'm sure many folks here would be interested in how well it performs!

In youth, we learn....with age, we understand.
