In an attempt to learn Lightroom, I decided to print my latest project in both Aperture and LR and compare the results. After seeing the results I realized I have a lot to learn about LR. The Aperture print came out noticeably better. The main issue was the LR print was too dark. Even after watching the first episode of TheLightRoomShow which specifically talks about this issue. Unfortunately I watched that episode too long ago to remember the recommended setting. I should have re-watched it first. The main tip they provided was to set the print brightness slider to something in the mid 20s. I didn’t set it that high and my print came out too dark. The main problem is LR doesn’t give you any feedback in the image. You need to print the image to see the results.
One big thing I miss from Aperture is the one button Quick Fix. For most images I found that got my images 98% there. I haven’t found an equivalent in LR.
