Photo merge
Challenge:
1. Sometime during the merging of multiple images to make a panoramic image Photoshop does not identify the images correctly and will not place them into the generated file. I’ve noticed that I could easily locate the correct area of the unused image data.
2. Sometimes photomerge will have difficulty in merging high contrast portions of the image. Example: sunset and mountains or trees. If the trees are dark (silhouette) and the sun is bright on the same frame there is no problem but if you correctly expose for the sun in one frame and correctly expose for the Tree in another frame photomerge cannot make a very good merge.
3. Why waste the data of all the overlapping images when make a merged file. Why can’t photomerge use that data to reduce the noise or get better overall tonal values?
Recommended Solution:
Allow the user to have more control over the positioning and coloring during the merging of images. This could be achieved by setting priorities or a weighted average to individual images depending upon the stacking order in layers. Individual images could be dragged and dropped into the predefined projection near the correct location and to be snap to the correct into the merge image. It would be helpful if auto masking would have similar abilities.
This would make it possible to have two differently very differently expose frames to be better merged together.
Can some portions of HDR processing be implemented into the photo merge process?

What you describe there seems to be in direct violation of the recommended procedure.

Quote from the reference (»Take pictures for Photomerge«):
»Maintain the same exposure
Avoid using the flash in some pictures and not in others. The blending features in Photomerge helps smooth out different exposures, but extreme differences make alignment difficult. Some digital cameras change exposure settings automatically as you take pictures, so you may need to check your camera settings to be sure that all the images have the same exposure.«
