Resizing your images for KPS using Adobe Lightroom

These instructions for resizing your images using Adobe Lightroom were made using Lightroom CC 2015.4 release on a Windows computer. Your edition may look slightly different.

We are assuming that you have edited your image to your satisfaction and are ready to export for a KPS Projected Image.

Once you have entered the image size, name, destination etc you can use the power or Lightroom to retain these details for later use by saving them as a pre-set. To do this simply click Add (near the bottom left of the export window), give it a name – I call it KPS Projected Image – (not very original I know) and then it is ready for the next time I want to export an image for KPS, either for an image evaluation or my member gallery.

I click the Export button which brings up the Export Window in which I choose the export settings I want. It’s easy for me as I simply choose the KPS Projected Image preset (highlighted in Blue in our examples) and click export.  I have now resized my image or images.  I’m done.

It doesn’t get much easier than this.

LR Export 1

If you have yet to make your preset, this is how to do it.

LR Export 2Note the three red rectangles in the screen grab at left.

I export to the Hard Drive (top rectangle).  I choose a specific directory on my computer desktop (middle rectangle). Note that I use a directory rather than just the desktop itself as I find this more efficient.

I call it KPS Evaluations. This is a temporary directory as it is renamed and moved once the images in it have been sent to our Image Steward.

In the final rectangle you will note that I have set it to rename the files as follows: KPSID-PutImage Title here-Put category here.

Although this title is not what I send to the Image Steward, it does put my KPS ID, the required hyphens in place and it reminds me to type the title and section. It doesn’t matter that the name appears to be the same for every image, for should I export more than one at a time Lightroom will add a digit to each filename to differentiate it from the others.

I then scroll down the Export window to choose my File Settings shown in the image at left (top rectangle). If you set yours exactly the same as mine you can’t go wrong. This means choose, jpeg, sRGB and tick the Limit File Size To and enter 1500 into the box.

Image Sizing is important and again, the settings in this image will work for you.

Tick Resize to Fit, Choose Short Edge, enter 1080 pixels.. The resolution doesn’t matter but I choose 100 pixels per inch. The resolution doesn’t matter because we are producing this image for projection, not printing. In projection, the number of pixels is the important factor, not the number of pixels in a given area.

Were I making a Panoramic Image I would choose 1920 pixels for the Long side.

LR Export 4

 

 

 

I scroll further down the Export box to set whether or not I want to adjust the Sharpening (I prefer to adjust Sharpening in Photoshop, but you may not).

I have Lightroom open Photoshop after it has exported just in case the image does need sharpening or further tweaking and also it allows me to inspect the image before I send it off.

 

 

When the image opens in Photoshop I can inspect it, alter it if necessary and re-name it for sending to our Image Steward.  I can also use Photoshop to check that the image has indeed been exported at the right size, which for KPS is a maximum of 1920 pixels (horizontal) by 1080 pixels (vertical).

As I used Lightroom to set the Short side of the image to 1080 pixels, LIghtroom automatically adjusts the Long side of the image to suit. With my camera and an uncropped image, this results in an image 1620 pixels wide.

Were I to be submitting a panoramic image I would alter the settings in Lightroom and choose 1920 pixels on the Long side for my pano.

Had I wanted to use all the real estate available to our Projected Image I could have chosen to crop the image in Lightroom prior to exporting.

Lightroom has a setting in the Crop menu that give us the correct size.

In the Develop module, Click the Crop tool (top left within the red rectangle in our example and then click on the figures to the left of the Lock icon and choose 16 x 9 1920 x 1080. This most likely alters the shape of your image and you can see the results on the screen, allowing you to recompose before activating the crop.

You could also save these settings as another pre-set, if you wish.

Pre-sets for export are a great way to save time if you regularly export specific sizes, types etc.
