LR 5.4 RAW to JPEG conversion taking too long. Is there a faster way?
3 months ago

So I decided to shoot RAW, then PP all files using simple presets, then quickly go through pics to manually fiddle with some pics requiring more PP. Finally I convert all RAW's to JPEG and keep them that way on my HDD storage. Once I did PP I don't need to keep RAW, since they take space and don't provide any benefits since I extracted all I want from them. I don't do any important shooting, just my family and trip casual shooting. I will not need to go back and reprocess RAW. So I'm using RAW as a best shooting mode to get most from the sensor and then PP to get it how I want. That's it. After that I need only JPEG - to view on our big TV screen in family room, to post on my blog, or send to friends for viewing etc. I don't do any publishing work and I don't sell pics, so I don't need to keep RAW.

I have an i7 quad core, 8Gb, fast HDD (7200rpm), Win 7 Pro and still conversion takes painfully long time - like at least 5 sec per 1 image. It sounds not bad, but yesterday I was trying to convert around 400 RAW's that I took from my recent trip to park with my family. You can imagine that it took more than half hour to just convert them to JPEG. I am already scared to think what will happen when i return from trip with 3-5k of photos? I usually go to file menu then do export and chose JPEG and folder destination. Seems simple and straightforward. Is LR not optimized or maybe I need to have really fast video card to speed up conversion process? I was under impression that it is CPU that is under load when conversion takes place. Is my i7-2860QM 2.5 (3.2) GHz not enough? Is there any other way to quickly convert RAW to JPEG in LR?

Another question I have is about that RAW to JPEG conversion. If I have a perfect RAW that I already edited how I want it and it has a beautiful DR (13 stops or whatever on base ISO100) - what will happen when I convert it to JPEG? Will JPEG retain all that visual aspects? I know it will not have RAW data in it and I won't be able to PP JPEG as much afterwards if I want to, but will it look almost exactly same as final copy RAW that I made before converting?

Thank you.
