MDM Posted May 20, 2020 Share Posted May 20, 2020 (edited) 20 hours ago, M.Chapman said: It all depends on the maths used to "linearise" the distortion. Pixel positions can either be remapped by shifting affected pixel values outwards (away from the image centre), in which case the original image size is retained but image quality at the edges is reduced as data is "spread out". In the other case affected pixels values are shifted inwards (towards the centre). In this case image quality is retained (and possibly enhanced were image data is squeezed together). But the image will require cropping and so the pixel dimensions of the image are reduced. I find it can be useful to turn off distortion correction on wide angle lens shots of subjects without straight lines as it improves corner sharpness. I can do this in LR or PS by altering the image metadata (using EXIFToolGUI.exe) before opening the image. Other packages (e.g. DXO) allow automatic lens distortion correction to be turned on an off, but not Adobe. Mark First paragraph is very interesting. I remember years ago using a Canon20D during a short flirtation with Canon using perspective control in Photoshop and the edgess of the image went to mush. That doesn't happen with anything I am doing nowadays in Lightroom working on raw NEF files - the edges are as sharp as the they should be. The bit about Adobe is incorrect as it depends on the lens. With Nikon it is only the Z series lenses (S lenses) that have built in profiles automatically applied, all others in my experience can be turned off. Sony seem to have been doing this for some time. However, if you click Custom Profile (talking Lightroom Classic here not older versions) and manually find the lens profile in the profile boxes, then it is possible to use the distortion slider on the Adobe lens profile. It is not clear if it is actually using a different profile and the differences are minimal or possibly non-existent in the case of the Panasonic raw file that you made available in relation to slide copying. I read in Martin Evening's Lightroom book that it is the camera companies forcing Adobe to use the built-in profiles automatically. Finally, I read recently and I can't remember where offhand that modern lenses tend to be geared towards sharpness at the expense of distortion as this is easily corrected in post nowadays and is almost certainly the reason that the camera makers are enforcing the use of automatic lens profiles.

MDM Posted May 20, 2020 Share Posted May 20, 2020 5 minutes ago, Harry Harrison said: A what!!? Yes 🤣 - back in June 2005 I bought my first DSLR - the Canon 20D. I bought a fairly expensive (>£500) Canon standard zoom rather than the kit lens and a 60 macro. I was never happy with the image quality from the zoom having been used to using Nikon primes on my film cameras. Fortunately I kept the Nikkor lenses (including the 55 Micro which has been seeing action again as you know). When Nikon brought out the D700 in 2008 as their first affordable full frame camera, I jumped back on board the Nikon ship and there I have remained ever since.

Must depend on the camera manufacturer too 😞. I just tried it on a variety of my RAW files. Canon G10 (fixed zoom lens) - Seems to work Canon G15 (fixed zoom lens) - Can't disable distortion correction in LR Classic Lumix G5 and G7 - Can't disable distortion with any of my Lumix lenses in LR classic, unless I use ExiftoolGUI.exe to set the "DistortionCorrection" tag in the RAW file to OFF. Panasonic/Lumix doesn't appear in LR's list of lenses I can select a manual correction profile for either. It's as if the "built in" distortion correction happens very early in the RAW decoding process in LR for some cameras/lenses. But DxO allows me to turn distortion correction on and off at will. It can really save some wide angle shots if corner softness is a problem. (As can using ExifToolGUI). ISTR there's a section on distortion correction, vignetting and CA removal flags in the Adobe DNG file spec. 28 minutes ago, MDM said: Finally, I read recently and I can't remember where offhand that modern lenses tend to be geared towards sharpness at the expense of distortion as this is easily corrected in post nowadays and is almost certainly the reason that the camera makers are enforcing the use of automatic lens profiles.

M.Chapman Posted May 20, 2020 Share Posted May 20, 2020 I see there's a comparison of the features in Capture One Express versions versus the full version here. It shows sessions aren't supported in the Express Versions. Mark Link to comment Share on other sites More sharing options...

I've developed my own idiosyncratic way of cataloguing images. However, I do prefer the processing tools in Capture One Express. Also, I end up having to do more tweaking in PS Elements after using DxO -- e.g. adjusting levels for Alamy, which is awkward in my version (9) of Optics Pro but easy in Elements and Capture One.

I see no loss of pixels when using manual focus lenses. Are you correcting distortion yourself using the "distortion" slider? The catalog is a complete mystery to me. I need to watch some "how to" videos. Maybe I'm confusing it with Lightroom. I haven't used the Rokinon lens in a long time. Link to comment Share on other sites More sharing options...

I had even toyed with the idea of buying the complete version so I could use it with my Olympus but it didn't seem worth it - there's such a steep learning curve and LR does a perfectly good job.

I do not backup the catalog as there are no images in my catalog (which I don't use) as all are in sessions and these all sit on an external hard drive as previously stated.

I currently have less than 300 images in the catalog, and the catalog "cache" file already takes up over 500 MB on my SSD. I wonder what happens if I delete the cache?

I use Lightroom but I've always wondered if C1 (Express or more probably Pro) might be a suitable replacement so I watched some of this video: https://www.youtube.com/watch?time_continue=1041&v=IqaZoskYy4w&feature=emb_logo They do seem to have quite a lot of videos and they are obviously keen to show how easy it is to switch from Lightroom or Aperture. The video seems to suggest that the catalog automatically creates 'Smart Previews" and you can choose how large these will be depending predominantly on your screen size so I suspect that this is where most of your 500 MB is going, that's only 1.67 MB for each of your 300 images after all.
