Cassandra - Working with large RAW images on the iPad Pro
By Graham K. Rogers
So far, the plan has worked as I had hoped when I ordered the iPad Pro, although there are some slight drawbacks. Transfer of images to iCloud is not a problem, although it may take a number of hours - depending on the number of images involved - before images are available on all devices. If I shoot (say) 100 images, this may take several hours to propagate to the cloud and devices, although the first images may appear within a few minutes. Any edits carried out may not be available on the Mac or iPhone immediately; folders used for photographs will not be updated until all images are uploaded; deleted files are uploaded then placed in a folder for the purpose (see below).
I have a number of apps that can be used to edit RAW files, including Darkroom (also on the iPhone), RAW Power, RNI Films, and the new Pixelmator Photo. As this only arrived in the last week, I am still finding out how this works, although I am reasonably impressed so far, particularly with the range of editing options it has available.
Some image editing apps on the iPad Pro
When I bought the D850, the large images caused me to make several workflow changes on the Mac, including the need to move away from Aperture as the RAW files are not supported. I tried several high-end workflow apps (I avoid Adobe), but none suited my editing or organizational needs, which include iCloud synchronizations so I can work with images on any device (even the iPhone at a pinch). Apple Photos does allow me some flexibility. It has a fair range of editing tools and I can also use certain third-party applications via its extensions.
For organizing images, however, I prefer not to use Apple's Locations, People and Memories; nor do I particularly like the app-specific folders. I use the basic chronological display. I find adding keywords a great help when trying to find specific images. I also organize my input into Files and Folders which, on the Mac at least, can be dragged around and reordered: this transfers to iOS devices. While albums can be created in Photos on iOS, I have yet to find a way to nest these in Folders.
USB-C disks: 2TB LaCie and 512GB WD SSD (right)
I cannot export images to the SSD from the iPad Pro, so until I can find another solution, I either have to import all from the camera to the Mac; or wait until iCloud transfers the images from the iPad Pro to the Mac, and then use that File > Export function. It's all a bit clunky. The first time I did this, I was not sure if the RAW files would be available on the Mac or if there would be some (considerable) time delay until they were downloaded. I need not have worried as the export (as shown in the Export panel) took the usual few seconds to the SSD drive via the USB-C cable.
The transfer of files to or from an iOS device is sadly limited for the purposes of photography. For the time being I will still need a Mac for some parts of my workflow.
