Ptgui Pro 9 1 3 Registration Key
Vida Hubbert
What am I missing? Any advice(es)? With PTGUI I need to give the program some controlpoints for a few panels it just cannot stitch without help. APP is really usually good at this, maybe this is too much.
I have to say that I'm not sure about the status of milky-way mosaics (@mabula-admin). This is already a pretty old post which might clarify some things ( -forum/distorted-milky-way-mosaic/#post-1384) but I have to ask Mabula about the best settings and if a better projection is still in the works..
hi, yes, tried it, curverture comes later then when adding more. adding them to a set of 3 and then stacking these did not work either, registration failure. at least I tried with the settings I permutated before which I guess are all except maybe a few strange combinations
I talked to Wei-Hao Wang about this a while ago when I asked him how he did his great 360 degree milkyway (his answer was sincere and long, well done manual work!) and he had suggested to Mabula before to implement a 360 degree projection, like PTGUI and many others have.
I reread all I could find and saw Mark's suggestion on turning the images again and that solved it. Actually crazy after trying every other combination before and failing. Maybe this should be implemented. Turning stacks can be a pain in APP, especially with larger files. Due to the time passed I forgot this possibillity, partially relieved partielly annoyed though... Does APP use swap files? Sometimes it does not work with their own created (big mosaic) files or is really slow. In Pixinsight these things are a lot faster
would it be better to do the bigger efford to subtract LP on each panel before doing the mosaic? So far I have never done this. Or increase LNC and maybe MBB and do LP & starcolor on the final mosaic? How to get rid of the curved milkyway?
Ok, so yes this should be improved and I know Mabula has it on his list, but it's unknown to me what the status of that would be. Personally I have had better success with getting each panel really processed nicely and indeed doing the LP etc. APP is not yet fully optimized for this field of view I think, but given what you have now it should work. I am curious though as to why the differences are so big, I'll ask Mabula that as well.
seems to me a combination of some things. Not sure if I got the colors right, but not this off. The shots were done for my daughter using an unmodded Nikon D750 with a Sigma Art 40mm lens at f/1.8, ISO 200.
No, agreed, I would probably need to take a look at the raw data myself, but am very limited in data transfer at the moment. So still waiting for Mabula. ? I reached out and he should be almost finished with his e-mail backlog and then attends here. @mabula-admin
I will try to make this up to you by working on your dataset myself to give you detailed advice on how to do this in the latest APP versions. Maybe we could use your data even for a detailed tutorial, like on your previous mosaic of the Milkyway and Rho Ophiuchi ?
So after registration, you want to use the l-c-registered image viewer mode in combination with the projection settings to plan the orientation of your integrated mosaic. For instance, load the reference frame of the mosaic and visualize it registered with the lc-registered image viewer mode. That will tell you how the mosaic will be oriented.
For data that has such a big field of view (larger than 120 degrees), you need the calibrated projective registration model, so you can use different projections like Equirectangular and Mercator. These two can project the data 360x180 degrees. (horizontalxvertical). You need to take this into account in how you want to project the field of view. I will soon introduce another projection that is able to project 360x360 degrees.
Now, If APP would register the data correctly with accurate optical distortion correction, then by using the projection rotate and move Center Of Projection options, you should be able to get the milkyway exactly like you want. Is this working now? Your latest images seem to indicate that it is working more or less, right?
LNC will not give you a perfectly corrected result in terms of gradients, it will only help to better blend the mosaic panels. You will still need to correct the result with the Remove Light Pollution tool. Have you tried that?
Off course, if you want me to give more detailed advice or how I would process this in APP, please upload the mosaic panels and I will work on it and I will describe in detail what I have done and I will show you the results. You can upload the data here:
I know that fully automated mosaicing can still be improved greatly in APP, i am working on a bit update of the registration engine with this purpose (also for comet registration) and I am planning for a rather big update/upgrade of the current LNC algorithm, which is needed to further improve things with regard to illumination differences in the data. It will take some time though before these upgrades/updates will be released still...
IMPROVED, 4) REGISTER, DIRECTLY ROTATE FIELD OF VIEW, you can now directly rotate the field of view of your integration/stack by setting the projection rotate slider. After registration, see your field of view of the registered data with the l-c-registered image viewer mode. Then adjust the rotate slider and view again, you will see that the field of view rotates. This is possible with both projective and calibrated projective models.
I have this idea of doing mosaics of a huge part of the sky (preferably H alpha, maybe even OIII - Ha bicolour), and this drew my attention to the Mollweide projection frequently used for all-sky projections.
First post your issue in a new forum topic, in the appropriate subforum, and please only try to upload your data when we ask you to do so. Upload details will be provided then. When the upload is approved, please make a folder with your name and issue, like "mabula-register-mosaic". The upload server address is :
PTGui belongs to the category of in-depth panorama stitching programs that offer a huge library of features, complex projections (the way your set of images are actually mapped), and powerful tools for adjusting how those images are blended. To get a sense of how much more control is offered, consider these two screenshots comparing the controls offered by Lightroom when stitching and one of the dozens of screens you can access when working in PTGui.
The overall interface is very clean, with a contemporary dark theme. The layout is customizable, to an extent, with the primary interface really being two windows, with one controlling project settings and the second being a resizable viewport for seeing the panorama and making adjustments directly on it.
I typically will finish my panoramas in Photoshop, so I love the PSB option. As a bonus, PTGui can output the individual frames as layers atop the finished panorama, letting you easily blend in singular elements or touch up any problem areas.
A very nice article about a very interesting subject! Thanks! Probably a definite must for the pro-photographer! I myself am just an interested amateur and a little spoilt by the ease of taking (many) digital pictures and then not going through with them but instead they just take up space on my harddrive ...
To at least stitch the panoramas together and get a quick look at them, with a minimum of job, I have used Microsoft ICE (free) for a few years now and think it is doing a decent job! Just drag and drop the pictures onto ICE - then it is fully automatic and it even has a autocomplete feature to fill in missing parts along the edges. I certainly prefer to use it over the Photoshop alternative - it is quicker and easier to use!
It is probably not anything a pro would use but if it has a relatively straight series of pictures it will do a quite ok job. "Easy" pictures like nature and landscapes turn out really good but indoor scenes with sharp edges pose a bigger problem. Lots of projections to use and zoomable preview to look for any misses before you actually commit to a stitch. Even if it usually manages to align the pictures it is pity there is no way to help the software find the control points if it fails. Autocomplete is good to use to get a "preview" how it would look if you put in a while editing it in Affinity Photo or Photoshop - but not always something you would keep! No limit to the size (according to MS) and you can set up structured panoramas of amazing number of pictures.
I used to use ICE - it was amazingly good. The problem was that Microsoft stopped supporting or distributing it. Eventually I had to get a new computer, and found I could no longer install ICE - or maybe it just wouldn't run, I don't remember. PTGui has more flexibility and the ability to fine tune the matchups - although as this writer points out that's seldom necessary.
Thanks Sven! Yeah, as I tried to point out, more advanced tools really make a difference when your image set is suboptimal - parallax, subject movement, etc. If ICE is working good for you, that's great!
What I find an underrated quality of this (or potentially other?) panorama editors is reprojecting single fish-eye or ultra wide shots. Of course there are others, dxo viewpoint seemed a nice one but isn't quite as capable.
I tried a few panorama editors but ptgui has been my long time favorite.
I've made hundreds of panoramas, gigapixel images and other composites in PTGUI, it really is the powerhouse that could. I have found nothing that I can't piece together with that program and as importantly, that I can project in thousands of varying views. I've sold many wall sized pieces of gigapixle art made in that program. 10/10 stars!
Dang. Should have bought it back when it was $100 a few years ago haha. Still probably worth it for anyone shooting panos. I've played with it before and it was phenomenal. The ability to click and drag your projection in real time is irreplacable. Every free alternative I've tried (Hugin, etc.) has come away lacking.
