I currently use Aperture and Elements and I am thinking of moving over to Lightroom. What if any problems am I likely to have switching over? Will my images be safe and useable as they are currently saved in the Aperture library?
It depends whether you are using a referenced or managed Aperture Library and what you mean by “as they are currently saved”
Many Aperture users have successfully switched to Lightroom but there are different approaches:
If you are a photographer, then Lightroom the better first purchase.
Lightroom has everything you need to make quick and easy adjustments (e.g.exposure/white balance/perspective correction/sharpening) to your photos.
Elements overlaps a lot with Lightroom, but it is really more for artists who wants to transform their photos (i.e. deeper edits of the source images).
Let us know if that helps.
