    Default Very Slow Lightroom images rendering

    I have a brand new 24" iMac, 2.93 Ghz, 4 GB RAM and upgraded graphics card GT130. I am running a legit version of Photoshop CS4 and Lightroom 2. Over the last few days I have been extremely frustrated with the slow speed of how lightroom 2 renders my RAW files in the Develop Mode. last night I was waiting for up to 30 seconds for images to render before I could do anything with them. They are large files ........ anywhere between 20 - 40 MB but I thought that a brand new machine with 4 GB RAM would eat this up. WRONG!! Does anyone have the same issues or any sugestions for me??

    Thanks.

    Hmm, doesn't happen for me - they're very quick.

    What setting have you used for image previews (when importing)?

    RAW files from what camera?

    what camera do you have?

    30 sec to render a 20-40mb raw file is normal. Remember, it's not like it just has to open the file...it has to interpret and render it as well, especially if it hasn't done it before.

    Do you generate previews on import or do you have it set to do that bit later?

    I have changed my preview on import to 1:1 preview. Should that make a difference?

    Well, it means the import will be slower, but when you switch to the Develop module the images are pre-loaded. That's how I generally have it set up for my desktop (but not for shooting tethered - I want the import to be as quick as possible for tethered shooting)

    Thanks fother. I'll soldier on with it and hopefully work it out. I was just dissapointed that it was taking 30 seconds to render one image. A brand new machine with upgraded graphics card should be smoking!!

    I'd suggest converting your files to DNG format on import.
    It's a safe archival format and they tend to load a bit faster.
    I have 22MP files on a C2D MBP with 4GB RAM and they only take 5-10 seconds to render at 1:1 zoom.
    Also make sure you are running LR 2.4.

    Fother. What are you importing your files into Lightroom as? DNG? Also what size files are you working with?

    Cheers

    I leave them in their original raw format.

    There are some good arguments for converting to DNG, but I haven't bothered. I don't have any particular argument against converting to DNG, and I'd be happy for camera manufacturers to start using DNG as a raw format, but I'm lazy on it. One day I probably will start converting... probably.

    Workflows are very individual things - it's a matter of deciding what works best for you - it's why Lightroom and Aperture are slightly different in how they work, but both cover a similar range of functions - they're similarly good products, but for me Aperture doesn't fit my workflow, for others I work with at times, Aperture is a much better fit than Lightroom.

    Personally I vary my workflow for either tethered or non-tethered shooting, but otherwise am working much the same flow as I was 3 years ago (using adobe bridge/camera raw/photoshop) but now all in lightroom. Barely use photoshop itself now. That's just me.

    So when I'm not shooting tethered I have lightroom generate full previews during import (and in importing I have a filenaming script to add my initials and the date to the image sequence number for better filenaming, as well as inserting copyright metadata etc) - the import is slower, but I just chuck on and 8GB card into the reader and pack up lenses/setup gallery templates for the clients/answer emails/get a beer while it imports . I'd rather that than pause for image rendering once I've started processing the photos. Again, that's just me. You should do what works for you.
