I think that when I get more confident with this program I’ll be using PSE less and less. In fact, experimenting with Affinity, I have now found that the CA removal tool in the raw development part of the program, also did a good job, much easier than messing about with the defringing filter later in the workflow in Affinity. However, since I wanted to use the raws directly in Affinity for HDR merging, I couldn’t take advantage of DPP. So my choices were DPP, which does the job excellently, or Affinity Photo. I was really looking for an easy way to remove it using PSE, but the stripped-down version of Camera Raw which comes with it, lacks the tools. In the case of my Canon 17-85 zoom, it is certainly worst towards the corners, worst of all at the widest zooms, even at smaller apertures, and the purple is most noticeable. However, it all seems to boil down, on a practical level, to having unwanted coloured fringes along (mostly) high contrast edges. I was somewhat confused by the terminology, and still am to an extent, because the terms seem to be used both as if they refer to different phenomena, and as if they are interchangeable. Easier to try and minimise at point of capture than later in software.Thanks. Such unfortunate effects are usually most noticeable when shooting into the light and it is the stray light bouncing around in your lens that make such matters more visible, so be aware of that when out shooting. Some lens coatings also are designed to cut down on the amount of CA and fringing occurring. It is often exacerbated by the arrangement of the glass inside the lens. I wonder if I could have achieved this more efficiently just in PSE? I did try masking to replace the highlights, but wasn't happy with my efforts.įringing (often called purple fringing) and chromatic abberation, are not uncommon on many lenses, (often a corrolation to cost, although you can pay thousands and still get CA or fringing). The best solution I've come up with is to convert the raw in PSE, then open the 8 bit TIFF in Affinity Photo, which did allow me to remove all the purple fringing and most of the green, at least down to acceptable levels.īTW, it wasn't a great problem having to use Affinity for this correction, because the Blend Ranges feature seemed to allow me easily to just use the non-blown highlights from the darker exposure to replace the blown highlights in the lighter exposure. But I don't know how to remove this fringing (CA?) in Elements. However, for a particular conversion I'm working on, PSE seems better for my purposes (using two exposures but not using an HDR tool). If I use the DLO feature of Canon DPP, it makes a very good job of removing it. I have a Canon zoom which has quite bad (fringing or chromatic aberration?- not sure which: I'm confused) at the wide end: purple on one edge and green on the other.
