Tailwagger Posted May 7, 2022 Share #1 Posted May 7, 2022 Advertisement (gone after registration) Aside from screwing up and forgetting to reset the resolution to 60 MPx after some testing, I've yet to spend any time with the alternate resolution modes. I simply have yet to find any important (to me) use cases that really required them. However yesterday that changed, as I discovered a valuable scenario after the fact that I hadn't previously considered. I happened to be out and about doing a few errands when I ran across a scene I found interesting. I was lens limited and so ultimately decided to attempt a panorama. I shot seven frames in portrait (hand held btw) which I then stitched via LR and exported to PS for processing. As you might imagine, the end result was rather large (21815 x 8432). So much so in fact that I ran my 64GB Mac completely out of memory while working on it, forcing me to close several applications to avoid crashing. Perhaps this use case was immediately obvious to everyone other than me, but I thought it worth mentioning for those who occasionally attempt similar things. The reduced pixel count modes actually provide a unique to Leica capability for generating manageable sized panoramas from a 60 Mpx camera. Welcome, dear visitor!

Ktsa5239 Posted May 7, 2022 Share #4 Posted May 7, 2022 (edited) Thats an excellent idea! I do loads of panos and the files are becoming so big that luminar keeps crashing! I will definitely going to try 18MP for panos! Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

AZN Posted May 7, 2022 Share #5 Posted May 7, 2022 > (21815 x 8432). So much so in fact that I ran my 64GB Mac completely out of memory while working on it, forcing me to close several applications to avoid crashing. Don't know what happened there. I used to do this stuff professionally on a 8 GB mac ~ 20 years ago. Never crashed or slowed down. Suspect your stitching software is a RAM/ system hog. FWIW I use an application called ptGui: https://ptgui.com Do panos just for fun now. Find 24MP per image more than enough to produce 110 MP panoramas after stitching. The M11's 36MP setting would be ample for this, or as you suggest even 18MP. FWIW some of my pano examples can be found on one of my websites at: http://www.theboomerlegacy.com/landscape/ 1 Link to post Share on other sites More sharing options...

I can stitch and develop in LR with no difficulty. The problems start when I export out from LR to PS to do some final tweaking. At that point everything goes tiff and the memory usage explodes. I always have a couple of browsers with dozens of tabs open, printer drivers, etc which further exacerbates things. Normally not an issue but when the image gets over 1GB on disk, things get a bit iffy. [EDIT] I should add that per activity monitor mem usage in LR alone was over 30GB.

LocalHero1953 Posted May 10, 2022 Share #8 Posted May 10, 2022 Leica (and I assume others) are having to become creative in justifying offering sensors with such large pixel counts. The number of people who actually need 60mp for the success of their images must be small. The Q (I have just acquired the Q2) is one example where Leica provides tools to make use of high pixel counts, with its digital zoom. The M11 offers both digital zoom and variable pixel counts. I suspect we shall see a lot more of this - high pixel camera bodies explicitly marketed not to show what a 60+mp image looks like, but rather the images you can get when you start out with a high pixel sensor.

On Apple 16 Max Not really, on the latest version anyway. Did you import 150 photos or so, work through them all and then do the pano? Memory usage mushrooms very rapidly and LR is often very reluctant to release it. Chrome and Firefox are even worse. All adds up. The Max is a likely upgrade at some point, but I'm getting my money's worth out of this one for the time being. Link to post Share on other sites More sharing options...

I still have the iMac from 2017 and works fine... Lightroom is always behind on performance. I can imagine they will ever catch up on speeding up the software enough for me.. Stitching Panoramas Benefit from better hardware, and for me getting the MacBook Pro MAX made sense. I shoot so many images to panorama as a architectural photographer. Most application at this point only use one apple core, so getting more will not always show speed increases . But you are right to close the browsers. they can keep all you ram in use if you have many tabs open.. Link to post Share on other sites More sharing options...
AZN Posted May 11, 2022 Share #11 Posted May 11, 2022 FWIW, the following article addresses some of the reasons why Adobe Lightroom CC runs slow: https://www.findingtheuniverse.com/improve-lightroom-classic-cc-performance/ From the article: Quote On my desktop, which has 64GB of RAM, Lightroom is more than happy to take up more, often sitting at between 20 and 25GB of usage. Yikes! I dropped L/R back in 2017 and never looked back. No wonder… Link to post Share on other sites More sharing options...
