LR updates & ACR updates

Maybe allready discussed here... here are the questions:



1. Lightroom uses ACR engine, right? After Lightroom's release, ACR v4.0 was released.. how's with Lightroom engine update?



2. I have Canon 350D and Lightroom shows using ACR v3.1 -I suppose that's the version which implemented 350D camera. How does Adobe handle with ACR... does that mean my camera (for example) won't be updated/improved in ACR anymore? Just for example (again), I may not like how ACR handles colors by default -does that mean it will stay so forever (350D case closed)?



3. When using Lightroom (switching to Develope or showing 1:1 preview in Library), I find ''Loading...'' time is too long -very long, compared to some other software. Does that time (and similar speed issues) depend on ACR core engine (only)?



Thanks for answers,

Bogdan

1. LR already has the equivalent of ACR 4.0.



2. That's when the camera was added and profiled. It's still going through the ACR 4 imaging pipeline.



3. Forget the ''loading'' indicator. Just watch the image. Sometimes loading stays up long after the image is finished loading.

Q1 %26amp; 2 -all clear :-)



About Q3: yes, I can start working on image while ''Loading..'' is still there -it's just that this doesn't make much sense as image is very blurry. Similar with 1:1 preview... I'd like to have it sharp there as fast as possible. IMO, if those times were faster, there would be impression of faster Lightroom in general.



Have a nice day,

Generally, I see the image get as sharp as it's going to get long before the loading indicator goes away.

If you select the files and go to Library %26gt; Previews %26gt; Render Standard

Previews (or render them on import), and wait until it's finished

rendering them all, the 'loading...' will disappear a lot quicker. It

also depends on the speed of your computer.

That's the case if you're switching to less than 1:1 preview (in Library/Develope) or if you've rendered 1:1 previews before or full preview is still somewhere in memory buffer.

I render medium previews (which is good enough for FIT view -overviewing photos). I also believe there's no point to have full (1:1) previews in database all the time (database grows tremendous) -engine should be fast enough to do that when needed. I don't expect this would happen instantly -but can be done faster than LR does.

When I switch to the Develop module, view at 100% and step through, say 30, Nikon D200 NEF images, no image attains its final sharpness until after the ''Loading'' text disappears (roughly 6-8 seconds). The *only* exception to this is if I have progressed through a number of images and then go in the opposite direction. In that case the ''Loading...'' text disappears very quickly for a few images and then reverts to 6-8 seconds per image.

Same here: image pops into focus at the precise moment that ''Loading...'' goes away. Mac also. Takes exactly 4 seconds on dual 2.3 G5.
