Problems with Photomerge

[sarahl31546411]

I have used photomerge many times before and it has worked well until this file. I am having trouble because the program continues to give me hard line borders between the images where Photoshop has merged the photos together that I cannot get rid of. I have tried redoing the merge many times with different settings with the same result. The images are all taken with the same shutter speed and aperture settings so blending does not work to get rid of the lines, in fact when I try to blend the images to get rid of the lines, the lines will stay while the blending occurs. I do not know the computer jargon to perfectly describe these lines, but when I flatten the image the lines will go away until I try to edit it, at which point they reappear. When I reopen the Photoshop document, after saving the document with the lines and close the program, the lines are still there.

I am using the current version of Photoshop and windows, and I use Bridge to bring the photos over. 

Thank you for any help or insights you can provide!

Sarah there are many versions of Phoromerge from CS2 to CC 2017.  In CS2 it was a a compiled Plug-in in layer versions of Photoshop Photomerge is done with Photoshop scripts that use auto align and auto blend.  The blending in the newer versions of Photoshop work better than older versions.  What version are you using  and what options have you tried?

I am using Photoshop CC 2017 and I have tried opening the images in Photoshop before using photomerge, selecting perspective, cylindrical, and spherical settings to see if anything would change.

Thank you.  You seem to have taken the image in manual mode with all setting the same this help when you stitch images.  I have 6 5MP jpeg Image I too back in 2003 I like to use to test stitching.  CS2 did not stitch them well back back then. I used PTassembler which use Panorama Tools back then to get good results.   Photoshop's Photo merge has been  improved over the years.  I have not been using CC 2017 because Adobe introduced a new bug in Scripting in CC 2015.5 which is also in CC 2017 scripting.  I also do not normally use Adobe Bridge.  With Photoshop you can stitch image from the Bridge and from Photoshop using ACR, Photomerge and Load image Files into a stack.  If I were stitching RAW files I would use ACR to stitch,   I will now test CC 2017.  I'll use Adobe Bridge to select the Thumbnails use menu Tools>Photoshop>Photomerge.  I'll capture the screen to show what I did, saw, setting used and results.  I get back with the Screen captures.

I had no problem.  Ahter the stitch I added as sharpeing adjustment lauer and save a full size jpeg.

Here is the fullsize sharpened jpeg. Right Click and open image link in a new tab you can the zoom to 100% there is an extra lens flair I could edit out.

ACR work well too.

Can you share a screen shot of what you see, and the actual image after you flattened it and save out a smaller jpeg? You say that the lines go away when you flatten the image and then come back when you try to edit again. I think this may just be a display problem possibly associated with your graphics card and the large size of the file.

Hi Theresa here is a screen clipping of what I am seeing,

[JJMack]

Your capture looks like many images were blended perhaps Stitched and blended or stack mode blended.  However I do not see any Smart object layer that could be an image stack and I do not see layers for each image used.  How are you using Photomerge. Some custom script or through Photomerge's Dialog?

Your Screen capture is not something I would expect Photmerge to produce.   I showed all the steps I used using Bridge and Photoshop.  Photomorge Produced a layered document one layer for each image used in the process each masked and blended.  On top of those  layers is a merged composite layer that has its transparent areas content aware filled.

You show  Layered Document a background layer and a background copy oh top which was lightened.  Your history palette shows all you did was open a PSD.

Pease show how you used Photomerge.
