What is a Virtual Copy? As the name implies it's a virtual copy :) "Regular" copies occupy the same amount of space on disk as the original image (and you can create them by copying and pasting). For large RAW or TIFF files it can be from 20 even to few hundred megabytes. Virtual Copy instead occupies just a few bytes. How? It's easy - it doesn't contain any image data at all, only metadata (like eg. Clarity, White Balance or Exposure settings). Then when developing a Virtual Copy in Lightroom it uses image data from the original image but applies metadata from your Virtual Copy.
To create a Virtual Copy you need to:
- Right-click on your image in Filmstrip .
- Click on the Create Virtual Copy item in the contextual menu.
To create Virtual Copy right-click on your image and select Create Virtual Copy menu item. |
Virtual Copies are useful for many reasons but here are the two most important in my opinion:
- You can easily develop the same photo with different settings (eg. in colour and in black & white). You could of course duplicate file on disk (by copying and pasting) but this would be very memory inefficient. It makes experimenting easier and more efficient.
- It's easier to derive fake bracketed photos from a single exposure (you can read more about this technique here) what is useful if you want to create fake HDR image from a single file. Let's say you need to create 3 images out of your single RAW. Using this feature you can simply create 3 Virtual Copies, set different exposure setting to each of them (eg. -2, 0,
+2) and exp ort them to Photomatix Pro.
