    We are back in Vermont and in the process of putting our house on the market.
    One realtor we interviewed seems especially plugged into hi tech digital to present our property. Here are the quotes:
    -HDR and flash photograph a technique used by architects that produce evenly exposed images.
    -Use of a 4K video camera w/associated equipment gimbals and a 4K drone
    Do you have any comments on his technology?
    Thanks for your help

  2. Hi, I’m here in vacation. My home photo group is unlimited vision from Waukesha Wisconsin. We are a PSA member. I’m going to Sanbel Ding Darling on Monday. What is the best time of day? Am or sunset? Any Egrett nesting site shots you can get with a 200-400mm. Any favorite spots? I’m particularly interested in groups of Egretts and spoonbills. Or babies but I’m aware it’s probably too soon for the latter.
    Best regards
