I was debating whether to show the finished product at the start or the finish of this tutorial. I decided on the start as the images in the tutorial are not finished, but raw untouched files. This is a tutorial on using “Smart Objects” in Lightroom and Photoshop CS4. This is a three shot panorama using a Nikon 24mm PC lens. I exposed all three images to get a mid point between blowing out the highlights, the sun and the waves, a crushing the shadows, the rocks in the lower section.
I am not a great fan of Lightroom. I use it because it does a lot of stuff that I can’t do with other programs. I really like the adjustments, but not the brushes or the gradient tool, as these are really quirky and not very precise. The steps that I am outlining in this tutorial can be accomplished by using ACR. I just happened to be using Lightroom when I began developing this procedure.
Here is what led me to this procedure. I had the three images that I wanted to export to PS Photomerge. I knew that there was a lot of work to be done to get the adjustments to all three images so that I could get a good blend. I made adjustments in Lightroom and exported to Photomerge. The results were pretty bad as it is difficult to get all three images to match when you are working on one at a time. With this option I had a daunting task of getting what I had envisioned for this panorama.I know you can open multiple images to compare in Lightroom. This got me close but not good enough. I thought how nice it would be to export the images as Smart Objects into one document so that you could stack them and do a rough mask so that you could get a good match of tones and colors. Only problem, Lightroom and Photoshop don’t play together that way. I could only export a single image as a Smart Object.
To make a long story short the following is what I came up with:
Step 1: Export your images as Smart Objects from either Lightroom or ACR.
Step 2: Right click on the empty area next to the layer name. This will bring up a menu as shown. Select “Export Contents”. Do this for each image. Close the images without saving.(You may want to leave them open the first time you try this, just minimize them.)
Step 3: Save the exported images.
Step 4: Create a new document. The size will vary with the size of your images. My images were 2832 x 4256 pixels. So I made this one 9000 x 4256 pixels. It’s more than 3x but I wanted some wiggle room. Make sure that the new document matches your color space and resolution.
Step 5: Go to “File” and then select “Place”.
Step 6: Select your saved image (from Step 2) and click “Place”.
Step 7: The image will open in the new document with a large X through it. This is to inform you that you can adjust the size of the placed image, not recommended for this project. Just click on the “Enter” key. You can now arrange the image accordingly.
Step 8: This is how your document will now look.
Step 9: Repeat Steps 5, 6 and 7 for each image. Your document will now have multiple Smart Objects. By double clicking on the Smart Object icon you will now be able to make all of your adjustments with ACR.
Step 10: After you have your images adjusted, you now need to export the layers as files. But first you have to “Rasterize” the layer. Right click on the layer in the empty area next to the layer name and select “Rasterize Layer” from the menu.This is so that you can import them into Photomerge as Photomerge does not work with Smart Objects. The last part of this step is to delete the “background” layer. This makes Step 12 much easier.
Step 11: After you have rasterized each layer go to “File” then “Scripts” then “Export Layers to Files”. This will create a new document from each layer.
Step 12: Open all the new documents that you have created. You will notice that you have a document with a lot of empty space. You will take care of this by going to “Image” then “Trim” and checking the “Tranparent Pixels” button in the dialogue box. Do this for each image and save the change.
Step 13: That’s it. Now open Photomerge and select open documents. You will be very surprised at how much time this will save you on very difficult images.
If any of you out there are up to speed with scripting for Photoshop this would be a great one to have (I’m biased).
