With the iris, I'm on the point of clipping the red channel and had to dial it back a little on the yellows to preserve what I could of the texture; hence the pastel shade approach.
If I push things a little too far into the clipping area I get this.
The fine petal detail is just beginning to disappear.
ps. This week, I've been experimenting with foxgloves and tall thistles to see if I can get tall whole plants to look acceptable; but there have been a lot, an excessive lot, of rejects and I'm still not there yet.
