After a bit of research on t'internet, I eventually went to the Canon support site to check out any software or firmware upgrades my brand new shiny 800d should have that might fix the CA problems with my ancient Tamron lens.
Nothing leapt out at me, but I did notice that Canon had an image processing application called Digital Photo Processing. Well, nothing ventured...etc: I downloaded it (though you have to enter the serial number of your camera to prove you are the owner of a Canon camera), installed it and fired it up.
When I opened one of the raw files exhibiting this severe CA the DPP software fixed it before my eyes automagically! I didn't have to anything except perhaps click on the image or change the White Balance. Your blogger is much relieved.
I shall have to explore what else this software does, but beware, dear reader, it only works on raw files.
I processed the photos in my previous post that were affected by CA, and redisplay them in this post. It was a rather tedious process as I fixed each file individually. I did notice a 'batch' feature which should allow me to process a whole load of files at once.
Hopefully, Canon will get around to issuing a firmware fix of this which I can load into the camera.
For those of you who do not know what Chromatic Aberration is (it took me a number of months to figure it out properly) here is a before and after example. The CA is a little on the severe side, but is fairly representative. Note, I have cropped a tiny area from the photograph. You don't see such wide fringing unless you zoom right into the photo - almost 100% zoom.
Now onto the fixed photos from yesterday's post. If you compare them against their equivalent from yesterday's post you might detect how much brighter and apparently in focus they are. Oh, I did take the opportunity to set the white balance to 'Daylight' rather than auto. It made the sky a shade more blue, and the greens a little darker. More representative of what I saw, I feel.
The upshot is that I do not have to remember to turn the focus ring 3mm to the left every time I take a landscape scene.
