> in horizontal lining is needed.Īl this has nothing to do with your question but more understanding what your doing wile correcting and that is also the case in applications.the same theory goes for horizontal lines so some / and ( If you over correct the image by straighten al lines, your place of eye hight is lifting to a point that you standing at 4m high. That artical does showed me why, The brain corrects by sampling wile looking up, focussing at smal points and rebuilding that to straight lines in your brain like to look at it at a more distance,

So as far as optical correction without any manual help it is doing a fine job i think.Īs far as viewpoint correction the auto mode does surprise me that it over shoots on occation at 100% and gets unnatural. There lens sharpening optic module does give a instant kick in the right direction. at first it looked less good to fine tune but because of the non realtime viewing of the corrected image the ab correction kicks in when zoomed in. Shading which is the mild form of vignetting.Ĭomparing to my other program vignetting can be done better at first glans but i find out that dxo has a wider image angle, uses less crop or uses more of the sensor?, to cut out vignetting. Pincushion/barrel things, aberration and vignetting.Īnd some things like lens corner light losses. So the optical module on dxo does three things in one automatic go, Probably not really your question answering but reading your quest started me to think about what is optical and what is perspective, non lens error, but point of view?Īnd this artical is rather clearing that up. alone, Lr handles this easily and I prefer Lr’s crop functionality.Ĭaveat: DPL can cause colors to change in a way that makes them hard to correct in Lr. Open original folder with DPL, correct images where necessary, save to Lr (architectural shoots) Note: Just lens distortion, leave keystoning etc.As Marie-Catherine proposes (general, mixed/nature shoots).Geometric noise means that lines/edges will be less sharp than they were before correction.Whether you’ll see this or not is another discussion though… Correcting geometric properties of a lens will therefore introduce some (geometric) noise in your images. But the source pixels are in a well defined position and if you move the pixels, they will miss their target location more or less because target positions also exist in predefined positions only. What is distortion correction? It changes the location of your image’s pixels in a way to make crooked lines straight. I didn’t find the right solution from the Internet. I want to be able to make all my image edit to the RAW data and then I’m happy to duplicate the files that require lens correction (obviously correcting distortion right in the RAW file would be ideal – ahem, Adobe?). IMO, distortion correction should be the last or next to last step if you’re output sharpening. I’ll give Nikon credit for at least making it “automatic” and possible on NEFs.Back to DxO – The main issue is distortion correction is really all I want to use it for and I’m a little frustrated by how it integrates with Lightroom – I can’t (or shouldn’t, according to DxO) make any adjustments to my file in Lightroom prior to correcting distortion which seems totally ass-backwards to me. This got me pretty excited at first as I thought Nikon must know their lens characteristics even better than DxO does, but it seems their correction method is more along the generic lines of what Photoshop does rather than truly customized to a particular lens and when comparing it to DxO results, they don’t look quite as good. I’ve been sort of obsessing about this for a little while now – I’m trying to determine the best course of action when it comes to dealing with lens distortion.I started out using Photoshop’s Lens Correction filter which works ok in a generic kind of way, then I gave DxO a shot which works extremely well for distortion correction (more on that in a minute), and recently tried Capture NX 2 as I noticed it has lens correction as well.
