Lightroom 2.4 and Camera Raw 5.4 Updates Released

If you don’t get prompted to perform an automatic update, in Lightroom and in Bridge, go to Help>Check for Updates to update to the new releases.   Lightroom uses Camera Raw when you use the  Edit in Photoshop command on a raw image, so be sure to update both.    Adobe only provides these updates to Lightroom 2 and Photoshop CS4, so if you have an earlier version, you are out of luck until you purchase an upgrade.

Information from Adobe:

Understanding Resolution

Two factors determine how big your image will be when displayed — the size of your image in pixels, and how many pixels are displayed per inch, which is referred to as resolution.

Both of the example images below have 6 pixels (3×2):  the first is displayed at  1 pixel per inch, and the second is displayed at 2 pixels per inch.

3 pixels x 2 pixels at 1 pixel per inch

3 pixels by 2 pixels at 2 pixels per inch

When you prepare your images for print, you specify  what resolution your images will print at.   If you have a 6 megapixel camera (i.e. 6 million pixel camera), your image is approximately 3,000 pixels wide by 2,000 pixels high  (3,000 x 2,000 = 6 million).      If you print this image (with no upsizing or downsizing) at 300 pixels per inch, your image will be 3,000/300 = 10″ wide, and 2,000/300 = 6.6″ high.   If you print at 100 pixels per inch, your image will be 3,000/100 = 30″ wide, and 2,000/100=20″ high — much larger, but it will look less detailed because at this much lower resolution the individual square pixels are larger and more visible to the eye.

When you prepare images for display on a monitor (such as for the web or for sharing by email), what resolution you specify is not important, because the viewer’s monitor will control the resolution.  For example, if you view an image on a monitor that displays 90 ppi, that is exactly what you will see, regardless of whether you specified a resolution of 90 or 3000 when you sized the file in the LR Export dialog or the PS Image Size dialog.    All you need to worry about is the size of your image in pixels, and whether this will fit on your viewer’s screen without alot of scrolling.  Since you probably won’t know for sure what size monitor your image will be displayed on, I suggest sizing your images to fit on most monitors.  Most people today have monitors that display at least 1024×768 pixels.   I therefore size my images for email at 800×600, because I know then that they fit well on most monitors, with room around the image for menu bars, docks, etc…

Check Out the Lightroom Lab and Computers for Photographers

There is so much to learn about Lightroom and digital photography, that I highly recommend visiting many website and blogs regularly (including mine of course!).   One of my favorites is thelightroomlab.com.  Check it out for great tutorials, tips, videos, news, reviews, discussions and more.  It is run by a very smart colleague of mine, Scott Rouse, a self-described “geek extraordinaire”.

Scott is a photographer, graphic designer, web designer, instructor,  and IT professional. He specializes in web design for photographers and other artists.  More information his web- and graphic-design services can be found at scottrousedigital.com.  In addition to his freelance work, Scott teaches photography and Lightroom/Photoshop workshops worldwide for Photographers Alliance Workshops.

David Marx is also a regular contributor to The Lightroom Lab.   David is an amazing instructor and  sports photographer.   His blog is also an excellent one for you to visit regularly — computersforphotographers.com .  In addition to news and tutorials on Lightroom and other digital topics, David focuses on the hardware side of digital photography — where many of us definitely need some expert advice.    David can also help you design and purchase a computer system (Mac or PC) that meets your specific needs.

Synchronizing Your Folders in Lightroom

You have imported a folder of images into Lightroom.  Later you add more images to that folder.   Have Lightroom figure out which haven’t been imported into its catalog and import them for you:

• In the Library Folders panel,  right-click on your folder (ctl-click on a one button mouse) .
• Select Synchronize Folder.   Lightroom looks at the folder and determines how many of the images it does not yet have in the catalog.
• Check  Show Import Dialog if you want to be able to copy, move or rename the files, add copyright metadata, keywords, or apply develop presets as the images are imported.
• Scan for Metadata Updates will look to see if any of the images already imported have been updated more recently in Bridge or another program.  (It will read check the XMP file.)
• Hit Synchronize.
• If you checked Show Import Dialog, go through this dialog as you normally would.

There are many situations where you may add more images to a folder.   Here’s one example:  a client of mine has a folder of scanned images.  This folder of images has been imported into Lightroom.  When she scans new images and they are saved into the folder, she now synchronizes the folder to get the new scans into Lightroom.
