I took this photo 3 years ago when Mrs Bailey and I drove around Tasmania over 2 weeks. Last night I had a bit of a play with various combinations of Hue/Saturation, Gradient Map, Levels and Photo Filter Adjustment Layers in PSE and ended up with this. Cradle Mountain - Tasmania (Enlargement is clearer)

Bailey, this is certainly a beautiful landscape and I can understand why you wanted to enhance the colors. Not that long ago I learned this trick for removing chromatic aberration when the usual fixes (Camera RAW, hue/saturation adj. layers) don't work.
Make a selection of your mountains and then contract a few pixels.....I tried it on your image and think I used 6. Place the selection above your image and use the free transform tool to cover the aberration. If you have the time, give it a try and see what you think.

Hi hmca, Thank you for your constructive criticism . I appreciate it but alas, I do not see any chromatic aberation on my original photo. When I do see some chromatic aberation in my photos it is usually blueish and/or purplish in colour and I use the colour picker in a Hue/Saturation Adjustment Layer to select the chromatic aberation colour and then desaturate it to match the neighbouring colours. My posted image has a lot of colour edits applied as I briefly summarised in my op. I also applied an outer glow coloured a shade of yellow to the edge of the mountain to emphasize the edge between the mountain and sky. I suspect any fringing you see in the posted image is most probably due to effects introduced when I down-sized the photo (which throws away a lot of pixels) for web publishing in combination with your and my screen being calibrated differently. Out of curiosity, how have you calibrated your screen?The print I made using the full high resolution version of the processed photo doesn't have any fringing along the mountain's edge at all and matches extremely closely with what I see on my computer screen.

Interesting, Bailey. My monitor is not calibrated. Perhaps, that is why I see distinct cyan fringing along your mountain edge. I'm glad to hear that you are happy with your printed image. Attached is a screen capture of what I see when I click your image above.

I see that you have edited your original post 45 minutes ago. The fringing is no longer visible on my screen. Attached is a screenshot of the same area.

Hi again hmca, Yes, all I changed was the resampling method in PSE when I downsized the photo for uploading from Bicubic Sharper (Best for reduction) to Bicubic (Best for smooth gradients). The original high resolution photo doesn't have any fringing along the mountain's edge. Also, maybe imgbb do something to the jpegs to help make them display quicker - who knows? But I do know they blur thumbnails (at least mine ) to some extent and maybe do something to enlargements as well. To be honest, it doesn't concern me if anomalies occur when resampling images for the web or if there are other subtle differences between what visitors see on their screen and what I see on my screen as obviously I have no control over the calibration and settings on a screen visitors are using to view images. The only thing that concerns me is that the original high res. image looks how I want it to on my screen so that there are no nasty surprises if I print it.

bailey,
Have you thought about using a different method to upload your photos to the forum? As you are a 500px member you could easily share your shots from there. This may eliviate the issue you are having regarding the fact that the images uploaded through imgbb appear not as sharp as they are.
I use Flickr to upload my photos here, as I am already a member there it is no great effort to hit the share button on a photo and copy the BBCode over to my gallery here. I find that I do not have the same issues with sharpness of my photos as when I use imgbb to upload.

Bailey and Helen I also noticed the problem where the mountain’s edge met the sky. I think it was not chromatic aberration and the problem was probably created during the editing. So, I decided to try Helen’s fix and it worked perfectly. Thank you Helen for the tip. For the record, I use Datacolor’s SpyderExpress to calibrate my monitor.

You're welcome, Pete. I did wonder how it looked to others with a calibrated monitor.

Hi PeteB,
As I mentioned in an earlier post, there is no fringing on the mountain's edge in the original high resolution photo - pre and post processing. I made a print of the high res. image before posting the low res. image and the print also looks fine.
It was only after I tried a different resampling method in PSE, as described in my previous post, that hmca observed there was no longer any fringing. To me it's clearly a resampling issue and/or something imgbb apply to uploaded images.
Hi Simone,
Most of the photos I upload here on PSE&M I don't have or need on my main gallery on 500px.
If imgbb is good enough for the PSE&M admins, then it's also good enough for me especially when it's easier to just click the "Add image to post via imgbb.com" button. If imgbb "massage" uploaded images for their own reasons, it's not a deal breaker for me.
