Thanks for the comments.
John, I'd take care of the watemark hereafter. Somehow I like that orange colour but I'd remember your comment.
Clive - I didn't expect good comment on the lighting. The parapet of the balcony is about 4.5ft so it is little dark inside the 'well'. Saw sunlight reflecting into the kitchen from next building and put a mirror to direct it to the flower. The speed at f/4.5 was like 1/50 or so w/o mirror and with mirror it went up to 1/160 on ISO200.
