comment What hobbyist landscape lens should I get to go with my Nikon D90?
Which kit lens? When I bought my D90, I had the option of two packages; one with an 18-55 and the other with an 18-105.

comment How to upload multiple CF/SD cards fast?
The using a single 32GB card sounds like putting all your eggs in one basket. Whilst having multiple cards of the same event means downloading is a pain, it does mean if a single card is lost/breaks that you lose a lot less.

comment Which Nikon kit lens is best to start with — or should I skip the kit lens?
I haven't done any detailed comparison on image quality between the two, but I suspect that you are right, in order to get a wider range of focal lengths there will have had to have been some more compromises made. In my situation I'd accept a slightly lower image quality for the increase in flexibility gained by having a wider zoom range, but your priorities may differ.

comment Is high ISO useful for photography?
I think I've finally worked out how the experiment works. The single variable this is changing is the position of the amplification in the overall signal path, which is affected by the ISO setting. In the ISO1600 example the majority of the amplification is earlier in the overall processing chain. Whereas when using ISO 100 the majority is later on. The amplification provided by the iso setting + post processing does remain constant. So the conclusion is the earlier in the signal chain the amplification is provided the better, and this is achieved by using a higher ISO.

But the brightness of the overall image is part of the output, which you expect to change as you alter the input variables, with all intermediate steps remaining constant.

comment Is there any significant difference between Nikon and Canon?
You said you were trying to decide which make of camera to buy, and as you pointed out and others have confirmed there aren't any major differences between the cameras so it is important to consider other factors that will influence your decision.

comment What solutions are available for a self-hosted portfolio website?
It said "don't mention photo sharing sites like Flickr, Picassa" this doesn't use the picassa photo sharing site, it uses the application which runs on your computer, so it meets the self hosting requirement rather than using someone else's infrastructure. I'm still getting the hang of this SE system so am interested in finding out how improve my answers.

Ok that makes sense, thanks for the extra clarification. I'm more used to Computer Science experiments where all parameters of the process except the one you are investigating have to be exactly the same.

My understanding is that of the 2 RAW images before any processing is done the ISO1600 image will have more noise. Yes, both images have had the same steps done on them in post, but the auto contrast function will have performed more gain increase on the ISO 100 image meaning more than one variable has changed so the experiment isn't valid.

Why the down vote? This answer was before the comment about being a web developer was added, so I went for the a simple solution that would achieve what was requested.
