I am having difficulty working with photos and iCloud. I am always running out of room on my 16 GB phone and photos are the main culprit. It seems (if I understand this correctly) that you can delete pictures individually and/or select them to be uploaded to the the cloud. If I could download them to my mac that would be great but I don't see how that can be done. Can anyone give me the correct iPhone 6 settings that will give me a reasonable "space availability".
