Adobe Lightroom ‘Parallel Processing’ Speeds Up JPEG Export by 50%

It should be noted that I use Canon Digital Photo Professional as my RAW batch processor. I have dabbled with Lightroom more than once or twice but never found the encouragement to switch especially when I had been computing on under powered hardware that would only make the whole experience excruciatingly painful. To  cut a long story short, I got a new custom-built Windows 7 64-bit PC last December moving up from two generation old 32-bit processing platform — a project that began with me nearly committing to an Alienware Aurora gaming rig but something else much better persuaded me otherwise!

Curious and better equipped than ever before I installed a trial copy of Lightroom 4.3 64-bit and imported 1,634 5D Mark II/III RAW files from the 2013 Lexus Golf Classic shoot. I first learnt of Lightroom’s parallel processing capability from ScottKelby.com who got the info from  MacPerformanceGuide.com and that was enough of a push to see how my investment fared. What happened next blew my mind, and I quote from the observation I posted on Facebook. I also shared this post on DPreview.com and Flickr.com

In the interest of benchmarking, I exported 1,634 Large RAW files to JPEG (Quality: 100) in batches of 400 images per operation in 4 operations (pictured above) and timed how long it would take to complete. Note that this is purely an export with no adjustments made to the images. Estimating the time it took me to separate 4 batches of 400 images each to be 1 minute in total, the entire export processes completed in under 15 minutes – impressive! Batching the same number of images in a single process took twice as long. — Facebook, January 21 2013

ASUSROG_SPECS_FBI ran the tests several times and on one occasion I had Canon Digital Photo Professional export 296 images from the same batch of RAW files with Lightroom this time running  not 4 but 5 parallel processes. The result was nothing short of amazing!

One hot weekend of Lexus Golf Classic shoot, 3 thousand images, several shades darker and 2 itchy sand fly bites later, this morning I decided there’s no better time to push the ASUS ROG 4.7GHz to export Cyril‘s 1600 RAW files in Lightroom and DPP simultaneously. The setup: Lightroom to handle 1600 files in 5 parallel operations and DPP exporting just 296 of the same RAW files (parallel tasking of DPP not tested here). The result is nothing short of mind blowing – my quick CPU tweak to 4.7GHz remained stable, LR finished exporting 1600 RAW to JPEGs in times I’ve never seen before (see top left image “5 operations in progress”. — Facebook, January 21, 2013

Using Canon Digital Photo Professional to Easily Create Multiple Exposure Photography

At the recent London Olympics 2012 Reuters photographers showcased the multiple exposure capability of the Canon flagship EOS 1D X all done in-camera (the EOS 5D Mark III is capable of this too). If you own neither (like me) you’ll be delighted to know I’ve found a way to get the same results using the version of Digital Photo Professional bundled with the 5D Mark III. The software has since received some updates so if you’re wondering which version that is, I’m not quite certain but the one I have is 3.11.31.0 — features the new Compositing and HDR tools — and because it’s DPP you can get the magic to work on both RAW and JPEG images. Compositing Tool is what’s needed for to layer several images for a stunning composite. The example below uses a series of images I shot using my Samsung Galaxy S III.

Canon Digital Photo Professional supports both RAW and JPEG files.

Anyone who has tried to make sense of layering techniques to get results like this knows it’s not a straightforward affair. DPP’s Compositing Tool is surprisingly easy to get results quickly and there are even options that let you control with preview of how the picture is going to end up.

Once the final composite image is saved, you can then make localized changes just as you would with any RAW or JPEG image to get the desired result.

Download the Missing Photo Editor on Your Samsung Galaxy S III

The Samsung Galaxy S III is supposed to ship bundled with a default photo editor app called Photo Editor but for reason it’s omitted from shipments bound for Brunei and some parts of the world. I’ve had the phone for over a month and since trialled about half a dozen similar free apps on Google Play. Among those I consider worth keeping are AfterFocus and Aviary Photo Editor while most others are just too Instagram-ish for my liking. While I do use Instagram occasionally I don’t use any of its filters. The photo editing tools I require are what every seasoned photographer know as basic exposure control tools and I’m glad I found Samsung’s own photo editing app to fulfil my needs. Best part is its Gallery integration for easy and convenient editing.

If this app is missing on your Samsung Galaxy S3 download here.

Once the Photo Editor app installed, it becomes an integrated part of the Gallery where you can now use the Edit function to conveniently process your photos.

The beauty of the Android operating system is you can opt to download OTA or on a Windows PC then drag the file over to the external micro SD card. Touch to install and life’s good. Once you’re done editing, Save the image and you’ll get a menu that lets you do a number of things including social media sharing.
