WOW This showed very creative elements. Thanks!
Just rented the Loawa 19mm shift lens for a Nikon z mount and started fiddling late yesterday and began to realized the complexity with multiple row pano that you described. Well I’ve got a long weekend to see what’s up.
fantastic video. great to see your workflow on how you use other apps too.
Thank you so very much for this great video Greg!
A very interesting video thanks Greg.
Thanks, I'd been scratching my head about having to re-define the export settings each time. Make default sorted it.
Amazing. Thanks for that. Really liked the techniques and result. I thought you would have shot with HDR bracketing, but looks no need.
I did bracket for testing, but there was no need/value in it here.
I'm very impressed by this PTGui stuff and by your use of it, of course. I'm curious to know if this result would be possible without the Pro version? Or, would the regular version be enough?
Regular is ok, but Pro helps generate controls points. Also supports HDR and batch work. ptgui.com/features.html
@@gregbenzphotography What would be the benefit of using the program HDR features, especially that it can take in OpenExr and radiance .hdr files? It's not clear if it can output such files, though. Also, other program can do that pretty well. Batch work is a feature I would probably never use anyway, the example you used is a pretty good example of why not. As for the control points, it seems that the automatic optimum seam placement is the only thing I would really miss, with the regular version, right? If I buy such a program, it is to save me the need to buy a TS lens or a back to hold my camera on the back of my 4x5. Spending thousands on a lens I would rarely use is not an option for me. I'm looking for the next best thing, if not outright a better solution.
It can output HDR from your bracketed inputs: ptgui.com/hdrtutorial.html
Did you try 3 rows of 5 (or 5 columns of 3) as individual images and then stitch the 3 rows using ACR/Lightroom? That has worked for me in the past.
No, but it seemed to put things in the correct place and I’m assuming it would fail too. Might be a workaround here.
Nice walkthrough. LR is terrible for complex pano's, photoshop a little better with multi-row but there is zero control to really make adjustments compared to ptgui. I miss Kolor Autopano Giga which was pretty awesome, too bad gopro buried that software. That sunray out of Luminar was awesome!
Thanks!
yeah, LR's RAW export is amazing when it works (which is often enough to be very useful), but it often can't cope with moderate to tough stitches. I wish PTGui would export RAW DNG files, that'd be incredible.
I used to use Autopano Giga as well, very nice software when it was available - powerful and pretty easy to use.
The sides of the image still look a bit distorted to me. And also left and right side have different distortions. But having tried something like that before I can only applaud you for getting it that far. I love multirow Panos. But, at least for architecture or anything that has a lot of straight lines, I have pretty much given up on it. Though I have not invested in a pano head yet. Do you think it’s worse it?
I honestly thought that by now the algorithms would be good enough to get perfect results even from a handheld multi row pano. I mean with all this Computational photography lately, it seems like stitching software (outside of a product like iPhone etc) is kind of an afterthought for 5+ years now. Or did you detect any major improvements there in the last years. In the stitching algo? Sure auto HDR Panos were added a few years back, but alignment issues are still mostly the same.
I’m sure I could push symmetry further if I weren’t trying to do the whole edit in 15 min, but it’s pretty close already with minimal effort.
I find a pano head (nodal slide and leveling base at least) is tremendously helpful. Better algorithms can help, but garbage in / garbage out always affects the final result. I don’t think handheld will ever be great for serious prints, you would have data discrepancies from frame to frame requiring the algo to invent data and resolve conflict in across a variety of complex scenarios. Works fine for phone snaps of distant objects, whole different ballgame for close subjects and high resolution.
nice tuto. Lot of powerful tools. Are you using a tablet or mouse ? with mouse i am using flow in photoshop to build the effect when scribbling. But with wacom tablet i have the feeling it is useless and opacity also allows to build dodge and burn by scribbling.
Wacom when I brush, mouse/trackpad otherwise. I use low flow with all of these and disable pressure sensitivity on the Wacom (I don’t like the transfer function, zero to full flow too quickly at the least sensitive settings). gregbenzphotography.com/photography-reviews/use-a-pen-tablet-for-better-photos-in-photoshop
So you angling upward for the top two rows with pano head rotations and no camera lens shifting wit was involved is that right?
Angling and shifted. If I angled without shift, distortion would have been worse.
Greg, are these three layers of five shifted or are you rotating the pano head about its nodal/centered rotational axis and only the distortion capability of the inherent 19 TS lens?
Started level with shift, and then angled subsequent rows upwards. Let me minimize distortion with the shift if the lens, but the required multiple rows certainly introduce challenges.
Did you try to stitch them with Photomatix?
As far as I know, Photomatix has no capability to create panoramas, just blend exposures for a single scene.
PTGui is a great pano program. Personally, I prefer shift lenses for panos, especially for Architectural Photography. I like the vertical lines be vertical. It's not so much a problem with landscape photography.
Agreed, that’s ideal. Wouldn’t have been able to get this shot with my 19mm tilt shift without ultimately panning the camera.
How can I put that image back to PTGU so that effect will be in my panorama?
I don’t understand your question, you wouldn’t go back to PTGUI generally for the same image, but should be able to save in process results if you aren’t done tweaking.
How easy would it have been to retain the verticals?
Very difficult without losing the vantage point that made it interesting
@@gregbenzphotography Thanks Greg, is it possible take the panorama shots with the goal of keeping the vantage point & the verticals, and if so how would you do it? I'm thinking adding another row of 5 shots at the bottom could do it? Or taking a step back and using a longer focal length with less perspective distortion?
Your pic is mint though, I'm asking purely from a technical standpoint
Not really in this case, I’m looking up at steep angle. It is what it is.
I think there are too many pictures. Half would have been enough and the pano wouldn't have been half the resolution. Less is often more. Despite everything, well done.
I've tried and it fails. Truly need this much overlap. It's a very wide scene with significant lens distortion due to wide angle lens.
