Looking for an accessory to carry with my travels for reading RAW photos off my DSLR onto my iPad mini. Does anyone have experience with option? It seems option 1 is to buy the Apple Lightning SD Card Reader or buying a wireless reader like this one http://www.amazon.com/RAVPower-Mult...65473&sr=1-1&keywords=wireless+sd+card+reader. (I'll be staying in hotels/places with wifi, not sure how spotty the wifi is. I also plan to use Dropbox if I were to get the Apple Lightning SD Card Reader) I read another forum post saying that the Apple Lightning SD Card Reader compresses the photos to JPEG, is that true? Thanks for the help!
