Hi dilbert.It is very easy to take sunset pictures without blown highlights. All you have to do is wait until the sun is well below the horizon, or you can use photoshop to subtlety darken the offending area in a manner so that the blown highlights will not be noticeable
Please could you show us a picture of yours to show us how it should be done, or if you don't have one perhaps a detailed explanation of the technique and processing needed to achieve no blown highlights. Whilst you at doing that the rest of us can take our pictures wih blown highlights and at least have something to show!
Cheers Graham.I can't believe how many of these images have blown highlights.
