Because Lightroom uses non-destructive editing, its adjustments are stored as metadata (processing instructions) rather than new image files. This means it can create any number of Virtual Copies of the same image for trying out different effects, without having to duplicate the image itself on your hard disk.
With Lightroom’s Smart Previews you can store smaller, lower-resolution versions of your photos within the Lightroom catalog while storing the full resolution versions on an external disk drive. Smart Previews are compressed DNG files and fully editable – any changes you make are automatically used for the full resolution photo when your drive is reconnected. Smart Previews make it practical to view and edit your image library on a laptop with a relatively small internal drive.
A new view in Lightroom that lets you place a ‘reference’ image alongside the one you’re working on, so that you can match the overall look and feel – this could prove very useful if you’re trying to achieve a consistent ‘look’ across a series of pictures.
A subscription plan which includes Lightroom CC and Photoshop CC. It’s designed for photographers and does offer very good value for money compared to the old scheme, where you paid a much larger amount for a ‘perpetual’ licence, and also had to pay to upgrade to new versions.
Image blending technology found in Adobe Photoshop, Elements and Lightroom. It’s used to stitch individual overlapping frames into seamless panoramas, or to merge bracketed exposures into a single HDR (high dynamic range) image.
An app for iOS or Android devices which works alongside the desktop Lightroom app to display images you’ve synchronised via Creative Cloud. When sync a Collection in the desktop app, that Collection and its images will appear in Lightroom Mobile. You can view and even edit images in Lightroom Mobile and your changes will be synchronised with the desktop version.
All-in-one photo cataloguing, organising and editing tool that also synchronised with a mobile app so that you can browse and share your images while you’re on the move. It uses the same RAW conversion engine and tools as Adobe Camera Raw, which comes with Photoshop.
A relatively new tool for adding depth and contrast to hazy parts of a picture. These are often seen in distant views, but dehaze tools can also add ‘punch’ and drama to low-contrast images generally. This tool does uses ‘localised contrast’ techniques to adjust different areas of the picture to different degrees.
A panel in Lightroom and Adobe Camera Raw which you can use to change the appearance of camera RAW files. The default Adobe profile can produce quite flat-looking generic results, but the Camera Calibration panel may also offer simulations of the camera’s own picture styles – for example, ‘Velvia’ for Fujifilm cameras or ‘Landscape’ for Canon cameras.
A comparatively new tool in Lightroom CC that fills in the blank wedges at the edge of a panoramic image stitched together from overlapping frames. Normally, you’d have to crop these off and lose parts of the picture, but the Boundary Warp tool ‘pushes’ parts of the picture out to the edges so that you don’t lose anything.
A tool used to ‘paint’ adjustments on to an image manually, and one of the key adjustment tools in Lightroom, for example. You may need to choose the adjustments you want to make, e.g. exposure, saturation, clarity and so on before you start painting although non-destructive photo editors let you make changes to these settings afterwards too. You can change the size, softness and opacity of the Adjustment Brush.
