Smartphone experiment

Love them or hate them, for mobile phones are very much part of every day life. For me it's my calendar, diary, sat nav, point of contact, and these days increasingly my out and about camera, unless I'm doing a proper photoshoot. Occasionally, very occasionally I use it as a telephone as well!

Adobe produce their well known photo editor Lightroom for mobile devices as a free app. There are many good editors out there like Google's rather excellent Snapseed, but Lightroom allows you to shoot in RAW/DNG format by opening up the phone's camera in the app and then selecting the RAW option. 

Enthusiastic photographers will know that shooting RAW has many advantages over in-camera JPEG, with one of the best being far more control over highlights, shadows, incorrect exposure, noise, white balance after shooting on the comfort of your home. The downside of shooting RAW/DNG is that the files are far bigger - much bigger!

Mobile phones tend not to give great results under artificial or low light, with colours being frequently off or muddy. So as a test, I thought I'd see how much better results could be using the Lightroom app to shoot a few snaps of one of my layouts, and then exporting the DNG/RAW file to Photoshop on my laptop to extract what I could out of the mobile phone images (an iPhone 7 in this case). I could of course edit a traditionally shot with the smart phone camera JPEG, but adjustment, especially white balance is very limited. Editing the RAW/DNG file allows far more control in this respect because you are accessing the original data before it's turned in to a JPEG in your phone which loses much of the data.

Okay, I'm blabbering and running out of time, I'll do a better feature on this if interest suffices!

  1. Chris, I'm no photographer, iso,wb and all the other technicalities make me dizzy but I do like taking pics with both my iPhone6 and iPad. So thank you for turning me onto Lightroom....now I just need to play with it and figure it out. I like adding pics to my posts in forums and it gets frustrating when a pic that looks good on my phone appears crummy and grainy in a forum post. Hopefully I can improve my finished pics with the Lightroom app. 👍
