For you it was 5 minutes. For me I would struggle for an hour. It is pretty much documented at this forum I am basically incompetent when it comes to working with photos. But I agree without the photo enhancement and the missed flowers I was heading down the wrong path. But since I am not going to be treating the pond over the internet, as soon as I reached down and grabbed a handful of the material up, I would know how to treat it. My business is not predicated on positive ID of plants from a distance. If it was, I would be best served like yourself becoming an expert with photo enhancement. I have zero desire to go that direction. I don't like working with photos, I do like visiting ponds and my customers on site. That is where my rubber hits the road. Or my frontline. If I ever felt my business was not fun and entertaining, I would stop it tomorrow. Playing with photos is not fun to me. Playing with ponds is.
