I took this shot last night (November 15) using my Canon 90D with my Sigma 150-500 lens. I also added my Kenko 3.0 TC The Lens was zoomed at 403mm with the 3.0 it would then be 1209mm I then went into Elements 2020 and used unsharp mask to sharpen the photo. The values I used was Amount 122%, Radius 10% and Threshhold 0% Do you feel I sharpened this too much?  Here is a side by side of the before and after:  I shared this on a photography forum. One person said this: You might try selective sharpening so you don't emphasize any over-sharpening halo and green fringing on the lower half of the Moon. I replied: "I do not know how to do selective sharpening.... what do you mean by the halo and green fringing? I do not see anything green? I use Photoshop Elements 2020" He replied: You should see the oversharpened edge on the bottom and left side of the moon along with a faint green color turn off and on every second. By selective sharpening, you should be able to use something like a lasso tool in Elements to just select the parts of the moon you want to sharpen so that when you apply sharpening, the edges won't get overdone. End of that statement I do not understand what he is saying in "a faint green color turn off and on every second" What are your thoughts? Did I over sharpen this photo? Thank you very much for any help you may have! |

Nice moon shots Inspeqtor. Not over sharpened to me.
I know nothing about "green" ... some lenses produce chromatic aberrations..sometimes green.
Not sure what your forum adviser means by selective sharpening. I often select just some parts of a photo for sharpening using the "quick selection" tool....say I want to do slight sharpening to a bird's head but the background is plain and already showing some slight noise...and sharpening will enhance the noise..so I might select the head only for sharpening. In the case of you moon, you could do a quick selection and then reduce the side of the selection using "refine edge."
Moon looks good.

Charles,
I believe the person on the other forum is talking about a very thin greenish (cyan?) line around the edge of the moon (the edge which is in the light). I am no expert but it doesn't look like this was caused by over sharpening as that line is visible in the "before" shot. It looks more like a case of chromatic aberration.
Try this (before you do any sharpening). Hope it helps!
- Create a Hue/Saturation adjustment layer.
- In the Channel box, select Cyans.
- Move the Saturation slider all the way to the left (to minus 100).
You should see that thin line disappear.

I think your moon shot looks fine as well.
Another way to sharpen your image selectively would be to use the high pass filter.
1. Duplicate your image
2. Go to filter>other>High Pass and adjust radius to your liking.
3. Change the blend mode on the High Pass Layer to overlay and add a mask.
4. Fill the mask with black...this will hide the sharpening. Now using a soft white brush you can paint in the sharpening just where you want it.
You can also change the blend mode and adjust the opacity.
Just read Sepiana's post and I do think I am seeing what she pointed out. So as she said you would do that first before sharpening.

Charles,
You said you used Unsharp Mask to sharpen your photo. You can use it and still do selective sharpening.
1. Duplicate the background layer.
2. Apply Unsharp Mask to the duplicate layer.
3. Add a layer Mask.
4. Use a soft brush and paint with Black to hide some of the sharpening.

Clive It turns out, what I did not tell you because I did not understand, he made a composite of my before and after shots, and from that made a gif file that blinked on the lower edge. I did not know he made a gif so I was not looking at the photo looking for flashing. Yes i knew he had my photo, he said he made a composite but I did not understand that would be flashing. He did that to try and make me understand the area that was slightly over sharpened. He did say in the end the green was very subtle so not to worry about it. Thank you for your compliment! |

I did not see the green disappear, probably because I do not SEE the green at all in my image anyway. After doing those steps, now when I go to Enhance/unsharp Mask.... unsharp Mask is now greyed out, not available. What I did then was "Save As" a PSD file called Saturation Adjustment Layer, then I saved it as a JPG file also as Saturation Adjustment Layer. I tried now to use the unsharp Mask but it was still not available. I closed the file out of Elements, then re-opened the JPG file and now unsharp Mask DOES work. Here is my new (hopefully better) Image:  A new before and after:  |

Oh yes... what steps do I need to include to be able to do the unsharp mask after doing the Saturation Adjustment Layer without having to close down everything first?

Thank you Sepiana... I just now did the 3 steps. After doing those steps, now when I go to Enhance/unsharp Mask.... unsharp Mask is now greyed out, not available. Charles, it looks like you had the H/S adjustment layer selected. You can't apply Unsharp Mask on such a layer; that's why this command was greyed out. Oh yes...what steps do I need to include to be able to do the unsharp mask after doing the Saturation Adjustment Layer . . .? You have more than one option. Merge the H/S adjustment layer with the moon layer. 1. Shift-click on the two layers to select them. 2. Do Ctrl-E to merge them. ORCreate a composite layer, a combination of all your visible layers. The advantage of creating such a layer is that you can work on it without affecting the other layers. When you run the Stamp Visible command, Elements creates a new layer at the top of the stack and then fills it with the contents of the other layers. 1. Make sure the top layer is selected. 2. Run the Stamp Visible Command by pressing Shift-Alt-Ctrl-E. |

Charles, My suggestion was to create a H/S adjustment layer and, then, select Cyans in the Channel box. Once you are done doing the necessary Saturation adjustment (minus 100) and you go back to the layer stack, the H/S adjustment layer will automatically remain selected (i.e., activated). This means that, when you apply Unsharp Mask, Elements will target the adjustment layer. However, as this command cannot run on an adjustment layer, it will be grayed out.  If you merge the H/S adjustment layer with the moon layer or if you create a composite layer, you will be able to apply Unsharp Mask. Now the moon layer will be the selected (activated) layer and the Unsharp Mask command will not be grayed out.  |

Here is another moon shot I took 12/13/2019 before 1AM with my Canon 90D, Sigma 150-500 at 500mm with my Kenko 3X ISO 1250 1/500s f/6.3 What are your thoughts? I did do a Levels and Sharpening with Elements 2020 Thank you for looking!  |
