Well said Gurcharanji This is very important now that this group is a few years old and most of its members have been watching the episodes and good photography and features essential for diagnosis, its time we had some more guidelines. the writing above is excellent . every body should bookmark this and put on the bookmark toolbar, I did. . its very important.
I have been saying this to various our members in various ways... but their habits dont change because someone of our experts comes up with an id... so it satisfies the asker ... and the habit of poor photography and all the excuses that go with them continue... so one habit the experts have to develop is to they need to be disciplined enough not to jump in with a diagnosis when the photograph is poor in quality or content.... I think you have been saying this repeatedly and so has Mr. Garg from time to time may be now is the time to make it a rule both for the person asking and the person jumping in to give a diagnosis on the meager information and poor photos... granted not every one has great photo equipment, but even with point and shoot in the pocket one can take enough pictures very quickly and provide enough clues... usha di On Fri, Sep 21, 2012 at 2:39 AM, Gurcharan Singh <singh...@gmail.com> wrote: > Dear members > Whereas Valley of Flowers has been a very enriching experience and all of > us have greatly benefited from this episode, it would be even more useful > if we learn from our shortcomings (partly because of pressure of time), so > that our next trip and its results are still better and helpful for experts > who spend their time and energy to identify these plants.
