I'm at my wits end and hope someone can help me out! I've spent hours and hours with Adobe tech support only to have a hard time understanding the thick accents and none knowledgeable enough to figure out the issue. And my case was dropped due to schedules; I was busy with Thanksgiving which seemed to make no difference to one who doesn't celebrate it! But I digress...
I really don't remember this happening in Lr 3.5, but it is in Lr 4.1-3 and only effects Sepia toned images I edit for the most part. Just finished about 200 images from an event where I will put them on a DVD to music for purchase. They all looked fine when I finished with them. I exported them as JPEGs, long side 1024, quality 74. The rest of the long story short, iMovie made them look awful, opted for iDVD. First time viewing them all was good, but after multiple viewings after rearranging/adding/deleting images from the project, they look like crap. For some very strange reason, many took on a pinkish/reddish coloration and often will introduce artifacts that simply weren't there in Lr. I viewed my edited images on 2 other Mac's and the issue remains, so not my computer.
I have an 27" iMac, OS 10.6.8 (completed up-to-date), 3.3GHz duo core, 12GB RAM, 960GB of free space on a 1TB HDD. Under warranty the display and recalled hard drive have been replaced, so my Lr 4.3 is completely fresh; not from a backup. With the new HDD recent, I haven't calibrated my computer as of yet. My images are on a WD 3TB with 1.25TB of free space (a tad on the low side but shouldn't effect anything). My camera is a Sony A33 and I shoot strictly in RAW set for sRGB; using ProPhoto in Lr and for sometime now only in Manual.
I would be so appreciative if anyone can explain why this is an issue. I need to finish off this DVD for the event and if I cannot figure this out, it's lost time and money! Admittedly I haven't been doing this for very long, so if it's something I'm doing wrong, I'd really like to know what it is...
Here are my examples:
