Category search as a button?

I wanted to feature two sections on my blog, my photography and my design portfolio. I wondered if I created posts under the two categories, there was a way I could hide the default blog page, but create ‘Design’ and ‘Photography’ buttons that just linked to a search for that category??? Would that work?

Or am I going to have to figure out how to set up a multi blog??
Thanks in advance for any suggestions.
