I recently bought Lightroom. However I'm finding it pretty daunting to use it at all. The manual seems to be written only for techno-geeks that use digital camera only. I'm sure, based on what I read before buying it, that its a powerful tool applied to film scans as well. But I haven't been able to 'find my way in' yet.
Therefore, I was forced to use iPhoto to make some display-sized (A3) prints for the first time last night. I was printing straight from Costco scans (2 to 5 Mb). They came out great... no tweaking needed. So I'm not going to worry about getting up to speed on Lightroom any time soon.
