I see it in multiple places, but I really notice it under the wings. Looks kind of oversharpened too which can account for some grain.

Hello there.

The whole photo has a slightly grainy feel to it. I think the easiest place to see this is the under surface of the wings. As an aside, though there is no clear reference, the photo has the feel of needing some clockwise rotation for it to look level.

It is certainly a very nice picture - where exactly is it taken?

Cheers.

Paul

P.S. Matt posted at the same time and beat me to it   . Hi there Matt!

P.P.S. As I 'P.S.'d' you posted too Mark. I would not appeal - I am confident that the Head screeners will see it as grainy too, and I would also agree with the slightly oversharpened diagnosis.

P(x 3). S. We are all posting at the same time! I figured it must be either Scotland or the Lakes. I don't know Scotland, but certainly could not place it anywhere within the Lakes - but the environment looks very similar.

Matt,

thanks. The grainy area under the wings is actually the reflection of the pebbles of the beach off the shiny underside of the wings. Would this be grounds for an appeal.

Cheers.

Paul it was taken at the base of Loch Lomond seaplanes, near Luss on the shores of Loch Lomond.

I've re-processed the image and reduced the amount of USM applied to it. To my eyes at least, this does not seem to be as grainy as the original.

Hello Mark.

This one is much better.

But still a couple of issues as I see it: now it looks as though it could benefit from a bit more sharpening, and also I would still be a bit concerned about the level. This might be a minor issue, but it is the lie of the land in the background that encourages the eye to see the photo as sloping slightly right to left. This is then replicated by the slight angle of the wings.

It looks as though you may have used the wheels as the horizontal reference. Just for interest I took the liberty (hope that's okay) of having a closer look and I used the horizontal reference of a line between the tips of the wings. This resulted in about 0.35 CW rotation. Not much at all, but I liked the result.

Good luck with the image - that rainbow is very nice, as is the landscape. If you would like any help with it, just say the word.

Cheers.

Paul

Hi Paul,

Thanks for the offer of help. Would you add a touch more sharpening to the whole of the image, or just certain areas of the aircraft?

There were 2 big problem areas with the levelling of the aircraft:

1. The background has a slope.
2. The slipway where the aircraft was sitting had a pronounced slope to it, from the aircraft's right to left.

I used the horizontal spar between the floats to level it - giving it around a 1.55 CCW rotation from the original.

Cheers

Mark.

Hard to say how to address the sharpening issue without looking at the original. I tend to start by adding one pass of USM, then look at the result and go from there. Do say if you would like me to take a look at the original. I certainly think there is every chance of getting this one up to the required standards.

I can imagine the problem with the levelling. But one thing I have learned is that it is important for the shot to 'appear' level. I can well imagine that the slipway has a marked angle to it - thus the motivation for correcting that. The problem for me is that I am still left with the feeling that that correction has left everything else looking sloped. It looks like all the water in the lake would fall off to the left.

Very tricky, I admit  wink .

Cheers.

Paul
