3 Image Editing and Size

LR – Editing

Your editing needs to be complete to the point where you are ready to crop and size your image, prior to printing.

Transfer Image from LR to PS for editing

Some members prefer to do their image editing and printing in PS, whilst keeping their ‘master copies’ in LR. Transferring images between products needs to be done with caution.  You risk degrading your LR copy of your image.

Return ticket

This is the recommended process.  Transfer your image from LR to PS with the intention of returning the edited version to LR. Use the LR option to ‘Edit in’. This option is available on a right mouse click while hovering over the relevant image in LR. When offered, choose to ‘Edit a copy with LR Adjustments’. This allows LR to automatically save back your edits when you close your image in PS. If you can open both products at the same time, you can see changes in PS change your master copy in LR dynamically.

One way ticket

If you have no intention of retaining an edited master image in LR, simply export your image from LR and reimport to PS. This provides an unattached, separate copy in PS. But from a print management viewpoint, this is one of the biggest mistakes you can make. LR is a superb relational database designed to look after your entire image collection. I recommend that you maintain every edited image in LR.

LR – Size

To establish the size of your print area, you need to decide on these issues;

  1. Print mounted behind your mount board (bled edge)
    • the bled edge is the 2 mm or so that sits (unseen) behind your frame cutout. In my worked example, the frame cutout, across the back is; 28×19 cm
    • print size needs to be 28.4×19.4 cm (4 mm bigger that the frame size above). This allows for a bleed area around the print that is then hidden behind the frame, cut in a 50×40 cm mount board.
  2. Print mounted behind your mount board (bordered edge)
    • your options include;
      1. an optional unprinted border around your print.
      2. an optional border line printed on the print paper (LR calls this a Stroke Border – any colour and width) around the image – see Printing a Border with LR.
      3. My current favourite option is: a 10mm all-round unprinted print border. It so happens that the aspect ratio of the print inside the A4 cutout is an easy to remember 1:1.5 (2:3).
    • I recommend that you calculate your print size as 10 mm less (on all four edges) than the frame cutout size. Therefore, SUBTRACT 20 mm from the frame height and width. If you use a LR Stroke Border, you don’t need to recalculate your sizing. This border is automatically placed within your print size. Remember to select the border colour and width carefully.
  3. Print mounted on the front of the mount board.
    • the print size can be anything that fits onto the mount.

LR – Cropping

Knowing our print size, we can calculate our aspect ratio (AR) for the print.

  • worked example (bled edge): 28.4 / 19.4 = 1:1.474
  • My favourite option as above: bordered edge inside frame 10mm (ie 1 cm) all round: (28-2) X (19-2) cm, that is 26 X 17 cm with an aspect ratio (set up at crop stage) of 1:1.5.
  • I recommend that having decided your size, you please a rule across the BACK of your mount, and see how your print size fits in to the cutout.

In LR, Development, select your image and crop to calculated aspect ratio (as above). Being non-dimensional, it should stay the same shape in the print module and exactly fit your print set up screen.

Having cropped your image to the correct AR for your frame, you can now print it to file and inspect it for any flaws by looking at it on your (calibrated) screen.

PS – Final Editing

You may want to transfer it to PS for editing, spotting, healing etc. Bear in mind the bleed are if any, and your edges. Please note the Transfer Image paragraph above for using PS  and save the image psd file back to LR.
