Template Suggestions

I am looking for something along the line of a responsive template, but am amazed at all the templates that look the same with a home page of large almost full screen images.
I am wandering are there any templates out there that have or easily allow for a slimmer image – along the lines of 900px x 350px. Simple menu below would be preferred. I know you can possibly adjust any theme, but wouldn’t know where to start for these images. I’ve tried with one responsive template and it inserted the image but left a large white space below it. I don’t know how to modify the code to do this.
