“How large can I print my photo?” is a question I get from Lightroom users all the time. The ultimate answer of course is - it depends. In the end you will need to do your own tests and find out what you are satisfied with. Below is some information that should help you with that process. It applies whether you do your own printing, or send your photos out to be printed.

Your photo has a limited number of pixels, or squares of information, in it, based on what your camera captured or what you cropped your photo down to.  For example, a capture from an old 6 megapixel camera is 3,000 pixels wide x 2,000 pixels high.  (There are various ways to display this information for a photo in Lightroom — try typing “I” once or twice in Library or Develop. Type I again to turn off the information display.)


When you decide on a print size, those available pixels get spread out to fit that print size. Here are some examples from that 6 MP camera:

4″x6″ print:  2,000 pixels / 4″ = 3000 / 6″ = 500 pixels per inch (ppi)

8″x12″ print: 2,000 pixels / 8″ = 250 ppi

16″x24″ print: 2,000 pixels /16″ = 125 ppi

This ppi is called the native resolution of your photo, at the given print size. It is what is inherently, or natively, available to you at the size you plan to print.

But guess what — your printer (or Shutterfly’s or Costco’s or anyone’s) doesn’t print at your photo’s native resolution!! It prints at what it likes to print at — i.e. at its own native resolution. Generally this is 360 ppi for Epson printers, and 300 ppi for HP, Canon and other printers. Continue reading »

When you click in a photo in the Book Module, a Zoom slider appears, which shows you how far, in percent, you are zoomed in on the photo, and allows you to zoom in more or less.  This slider is for enlarging the photo in the cell on your Book page, not for zooming in to evaluate detail in the photo. (The latter is done with the Preview panel.)

If you zoom in too far, you’ll get an exclamation point in the top right corner:

Book Module Photo Zoom

If you click on one of these exclamation points, you’ll get this warning, indicating that you have enlarged the photo too much and may not have enough pixels per inch (ppi) to get a good quality print:

Lightroom Book Exclamation Point Resolution Warning

Note that this warning and ppi information will only display if in the Book Settings panel you have chosen to make a Blurb book, not for PDFs or JPEGs. In addition, of course, it only displays once you get down to under 200 ppi.

So how do you get Lightroom to display ppi for PDF’s, JPEGs, and for your Blurb book photos over 200 ppi?  Here’s the secret:

  • Click in the photo, so that the zoom slider appears.
  • Hold down the Alt/Opt key — this changes zoom % to ppi!

In this video tutorial, learn about the new features in Lightroom 4.1:

  • Color defringing in the Lens Corrections panel
  • HDR file support
  • Book output option to JPEG (my favorite!)
  • Adobe Revel move to Publish Services

(For higher quality, once you click on the play button, click on the sprocket wheel at the bottom of the screen and choose 720.)

Tonight at 9 pm Pacific Time, Adobe announced the official release of Lightroom 4.1.  This is a free update to Lightroom 4.0, and addresses several bugs in 4.0, and also adds new camera support. In addition, we have for nice new features:

  • Book output to JPEG. We can now save our book pages as individual jpegs. Not only can you use this to send your book to a publisher who requires jpegs, but more importantly to me, you can make single page photo/text layouts (which you can reimport into Lightroom to print or use in a slideshow).
  • New Lens Corrections tools for fixing purple and green fringing. In the Lens Corrections panel, there is a new Color tab, with the Lightroom 4.0 Remove Chromatic Aberration check-box, as well as the new purple and green controls. For automatic correction, click on the eye dropper and then click in the purple or green fringe in your photo (while zoomed in to 1:1 or greater), and Lightroom will detect and set the sliders appropriately to correct it. Amount controls the strength of correction, and colors between the two Hue triangles are affected.

  • New local purple/green defringe control in the adjustment brush and graduated filters.
  • Support for HDR TIFF files (16, 24 and 32 bit). Now once you have merged multiple exposures using Photoshop’s HDR-Pro, you can do the tone mapping nondestructively using Lightroom’s Develop module, rather than Photoshop’s complicated (and destructive) tone mapping dialog. Files from other HDR programs are also supported. Note that 32-bit PSD’s are not supported, so be sure to save in Photoshop as a TIFF.
  • Adobe Revel has been moved to Publish Services

In this very popular presentation, Laura will discuss what makes Lightroom so attractive, explains how it works differently from other programs, and give you a tour of the fundamentals of the program (Library, Develop and a brief view of Map) by importing and processing a photo shoot. Whether you have never seen the program and are wondering if it is something you should consider, or you already have it and wonder if you are leveraging all it can do, this information-packed lecture is for you. (Lightroom 4 will be used, but it is also applicable to Lightroom 3.) 90 minutes, FREE .
