the panorama as a whole, by setting the center point, or by changing the projection and blend modes. Select Create Panorama, save as a TIFF fi le if you’re happy with the blended preview, or save as a PSD fi le if you want your blended image to also contain the original image fi les as layers. This can be useful if there are stitching issues, which can then later be fi xed by using the brush tool to add and subtract elements within an adjustment layer in Adobe Photoshop. Adobe Lightroom: import the series
of RAW images (rather than processed TIFF fi les) and select all. Right click on the highlighted series and select Photo Merge then Panorama. The Panorama Merge Preview display appears with the output image displayed. Choose Auto Select Projection if you want Lightroom to automatically select a layout projection. Otherwise, choose your own projection (Perspective, Cylindrical, or Spherical) depending on which projection produces the best panorama. Finally, select Auto Crop and then Merge to create the
panorama and place it in your catalog. The panorama will now be saved as a RAW file, so it is possible to make RAW adjustments to the processed panorama, which is a major benefit compared to the other programs above.
Crop and Final Adjustments Open your fi nal image in Adobe Photoshop and enlarge to 100 per cent to review and ensure that key elements have been lined up and that there are no unusual or mismatched features in the fi nal panorama. Choose the Crop Tool and crop the image as desired; you can set-up a traditional 3:1 panorama crop ratio at this stage if you wish. Final adjustments to levels, curves, saturation and sharpening can now be made to complete your perfect underwater panoramic image.
