Blotches. Any thoughts?
All the gear with no idea
Looks like stuff floating on the water surface. They're sharper closer to the bird.
Not sure Haris if he's talking about the stuff floating in the pond or there seems to be a touch of flare maybe or something on the lens, roughly mid wing on both shots.
As Haris said, the green bits are of course perfectly natural.
I know what i like, If not always why.

Don't mind me.

:/
Don't mind me.
Of course we'll mind you, someone has to



Doesn't look like moire to me, looks lens related ( I could easily be wrong though ), have you tried taking the lens off and shining a light through to see if it shows up anything ???

I initially hadn't made a distinction between the marks in the background, and the marks on the birds wing. Looking a bit harder, and considering the replies so far, I'm inclined to think that the large number of blotches are indeed things floating on the water.
I don't think it's dust or marks on the sensor, as it's in different locations in the frame, and it's only this handful of pics that they show up on.
The marks on the birds wing could well be lens related, eg flare, as suggested. There was no filter attached to the lens and a hood was being used at the time.
I don't have the lens to hand, but I'll give it a good going over when I can.
Cheers folks.

I've only just got around to looking properly at them, and while most are OK, there's a sequence of about 6 shots that have odd random blotches on them. Hopefully they're visible on the images attached.
Any thoughts? Cheers.
