This what i get when merging 3 vertical images in Lightroom shot with D850 and a Schneider TS 28mm lens. It used to work fine, but now no longer. It works fine in Photoshop. My other 2 Nikon TS lens 24mm and 19mm work fine on both platforms. Am baffled. Help please.
Are these raw images or did you create derivatives (tiff)? Lightroom is extremely picky about things like image size. The images must have absolutely identical pixel sizes; a difference of just one or two pixels already makes it fail.
I use Nikon Capture with my D850 tethered to Mac Book Pro and images show up in Lightroom directly. Settings are Image Quality NEF (RAW), FX 36 x 24, RAW Image size Large (8256 x 5504), Lossless Compressed, 14 bit. The 3 images are selected in LR and Control/M keys are clicked on, but merging fails. (images are not edited before in anyway)
I see no clear reason why they would not stitch, but they indeed also don't on my system. Also not in Camera Raw. I suspect that the overexposed bright doors are throwing off the stitching process, but as you've shown, other software (including Photoshop) can deal with that without a problem.
Dont think it is the light problem, as i have tested it on other images that are less dynamic. would you have any idea whom i might ask, as i do this for a living and it slows ever shot down having to constantly test the image in PH. and BTW thank you already for your help. the difference between the Nikon and Schneider Krutznacht is it has no electronics at all. but there again, it was working fine before????
You're on the right forum for asking. What I do know is that missing lens profiles makes Lightroom complain when doing stitching. And the use of perspective control lenses also complicates it, because Lightroom does not always know how to distort the images to get the perfect match. Maybe these shots were taken with more shift than others? So while I'm not completely surprised that the stitching failed, if it worked before...
Nothing has changed in the way I shot the ones that work and the ones now that don't anymore. I do a full shift to one side - shoot, then rotate the lens 180 deg. to the other side, rotate the camera back to the upright position - shoot, then shift back to center for the last shot. No tilting involved, although, in the past I have done that too, successfully. Exactly, it worked before????
Sound great, but in real terms, what does this mean for me and when can i expect it to work again for me and what , if anything, will i have to do on my side.
This is what i am told, but need to thank you for your time and for caring........ The engineers identified the issue and have logged a bug for it. Thanks for reporting and providing sample files.
Rikki - Got a new one for you. In Lightroom, when I HDR some bracketed images, the results come out with patches of excessive noise. Have no idea why and I have to resort back to using Nik Efex Pro 2. Here is a Dropbox link to view 1) The 6 dng images, 2) the resulting HDR dng where patch noise is visible, 3) the final jpg image that was made with Nik . https://www.dropbox.com/s/xgwd57e7w13l760/Noise.zip?dl=0 Tx, Christopher
Hi Christopher. Maybe you have deghosting on. It's not the best feature of the HDR merge but I've seen this noise you're referring to before and it was when I forgot to switch it off when I didn't need it. Switch deghosting off and try again.
Hi Jerry, You are right. Noise problem gone, but now I have a ghosting problem. Is there hope that LR will be improved in this matter in the near future?
Ha, God knows! They are reading these posts and have made some improvements to merging in recent releases so there's always hope. In the meantime, try playing around with the different levels of deghosting. Low might work best.
I will, but thanks either way for your time. and if ghosting is a problem there is always Nik Efex, but that software annoyingly only spits out a tif file.
I am having the problem of 'Unable to merge photos' far too often lately. I set the deghost amount to 'none and I've finally had success but it shouldn't be like this.
