Ghosting, I think

The arrow points to a flower pedal which has some ghosting, or some damn thing. Is it ghosting. At any rate, can it be removed, and fell free to try. I would appreciate it. Seamus

Might be your filter or lens. I get the same thing when I use my CPL....and its not a cheap CPL either. It shows up when the filter/lens has an item in the photo that has a contrast area at the exact focal distance where the light fails to converge properly onto the sensor. I am COMPLETELY guessing here and I am sure there is a better explanation. Could it be is at the exact location of the beginning of the most evident background blur beginning and you just got unlucky that it happens to fall on a high cintrast area (light petal with dark background)

I notice you dont see it in other contrast areas and there is no camera shake evident...

Do you get this with other lens/filter combos? Did you try this shot at different aperatures/focal lengths....seen it before in your photos?

Not that I have noticed. I had a Canon 100-400mm L, and I don't remember ever seeing this. Since using the Canon 70-300mm I see it in some pictures. I don't have a filter. Thanks crazydaddio.

The depth of field is very short when shooting at 300mm from a very short distance. I do believe that what you are seeing are out of focus edges on the most distant petals.

Thank you. How could I have taken a better shot, what's the remedy?

Couldn't ask for much better with the equipment used.

I Know, I feel that way two. My Nikon D7100 and 80-400mm lens were stolen in a break-in, no insurance. Thanks

It's chromatic aberration (CA), also known as colour fringing. The reason why it's inconsistent throughout the photo is that it varies depending on the difference in light levels (contrast) either side of the edge in question. And depending on the lens, it may vary depending on the amount of zoom and may be worse close to the edges. In your shot it's worst where a bright petal has a dark twig behind it, but you'll notice it's not limited to that area.

CA is one of the factors that lens manufacturers put a lot of effort into minimising. As a general rule, expensive lenses will be less prone to it than cheaper lenses (is 70-300 a kit lens?).

You could try a de-fringe tool, but that will probably just get rid of the colour of the fringe rather than getting rid of it completely. Lightroom's 'Lens Corrections' section recognised the lens, but checking the 'Remove CA' box didn't do anything. I tried the de-fringe tool in the Adjustments brush but that just removed the colour of the fringe and left it grey.

Thank you. No, it isn't a kit lens but it's no L Series.

Hmm. You may be right. If you zoom in to the other contrasty petal transitions you see it there also....just not as pronounced.
It appears to be "green fringing". I think it is more pronounced the greater the contrast transition and generally worse in the mid-transition to " out of focus.". Not sharply focused but not quite blurred yet.

It is there in both focused and fully out of focus just not as noticable.....

The ghosting is easy take out with my cloning tool. But that damned arrow. That's a tough one.

Look at other images. If you were using Autofocus, try AF-S, or back button so that the camera isn't constantly seeking focus.

I think we're all looking forward to the day when the software writers eventually get round to giving us that much-needed arrow removal tool .

(I've heard that there's a plug-in available from a company called Arro-Gon... ).

If you have a filter on the lens, try shooting without it. Might help.

But it isn't always avoidable.

Yes, it can be retouched, but it's more work.

BTW, did you know copyright laws changed about 20 years ago? You no longer need to use the Ⓒ symbol or put the date on your images. You can simply "sign" with your name.
