Problem child.

[Solar]

I shot some footage last week for the express purpose of creating a Hi-Res mosaic. It consist of four prime focus shots of the disc and proms.
All shots are the same configuration and settings and number of frames.
All were completed within 10 to 12 minutes. Number of frames about 2000 each and 250 best stacked in Registax6 and flats applied. Prom were done the same way after the disc. I have tried to blend the images with and without the proms.
The problem is Photoshop CS6 merges all four images but separates the top and bottom. For some reason it joins the two haves ok but puts the top on the bottom and bottom on top as two separate images. Tried joining from north to south and it kicks out the NE quarter. Here is the NE quarter in B/W and colour and the two halves as PS produces them.

Any ideas :help:
PS Have already thought of the garbage bin :confused2:

Still ...they are great shots ...nice detail.

For the easiest way to get this mosaic together put the 4 files ie each quadrant, into Microsoft ICE and it will Align and modify to a seamless mosaic.

I have yet to see any stitching program beat AutoPano.

Can you post the four frames here or (if you don't mind) the full resolution somewhere?

Thanks Allen,
I will download and have a crack at it.

Hi Andrew,
No worries here they are. The Tifs are 10.5 megs each, I will send them to you on disc if you like. My web site will be up in about 2 weeks I hope then you can down load any of my images.
Thanks I really appreciate the help. capt.ralphsmith@bigpond.com

I have used AcroPano before without issue. It was even a Give Away of the Day recently.

Works well.

Just tried it in ICE - doesn't like the 2 east quadrants. It'll stitch the 2 west quadrants though. Hmmm.

EDIT: Got it to stitch the 2 lower quadrants fine, but now not the upper left.

Threw it into PS 5.1, and it seems the upper left quadrant is of a different scale than the rest. I managed to NON-SEAMLESSLY merge it, but...

The upper left seems to be the problem child.

Great image,lots of filaments.

Thanks to all. I think there is some problem with the N/E shot. No idea what though as all were taken together. Tried three different programs to no avail. Managed to sprag one effort in CS6. I will try another series when the sun returns. (cyclone on the way)
Any good ideas on fixing the hot cross bun effect on the overlap. I am new to mosaics. :screwy:

That last pic is pretty good.I,ll leave the mosaics though I have a hard enough time using CS as it is.

Very nice Ralph, plenty of great details on each of the shots. I had a quick look at the panels, seems to be a very slight shift in scale, but you have sorted that out in your latest version, well done! The hot cross effect looks like a blending issue, you may have to play with overlap contribution from each panel.

AutoPano managed this. It does not like greyscale so I converted to RGB and turned off focal length correction.

Thanks Andrew,
That has improved the blending effect (hot cross) as well.
I will download it and try. With your result HDR Toning should fix the blending issue.

Ralph, I can give you the 50% size PNG or re-render it as a 100% PNG. The 50% one is too big to upload here.
AutoPano would have no problem with the 4*10MB tif. I have Giga which can handle seriously huge images.

A really nice mosaic with a great amount of detail. Glad that autopano works.

I manually merge mosaics in photoshop, I never tried to use automatic software.

If you put the original files on dropbox while you are waiting, we can download them and take a look/have a go.
Dropbox gives you 2GB of space and is completely free. I'd love to take a crack at your data!

If you use the link below for dropbox, you get 2.5GB, we both get extra space :)

That second autopano shot is an improvement, but 'hot cross' at the 4 panel boundaries is still present.

Ralph sent me a link to the images - on DropBox. :)


The full size TIFFs merged better.

Excellent set of images!
