On a recent excursion to the Skywalk at Santa Pola, Alicante Province, Spain to shoot some pictures for stock I only used the Sony RX100M3. I'm familiar with the camera and popped off a few shots to upload to my stock portfolio on ALAMY.
It was mid-morning and the light is pretty poor, particularly looking out to sea, so the best shots were to be had in the opposite direction.
The best way to achieve better results was to put the RX100 onto a monopod and use the wifi remote control feature to take some shots from high up to give a better scale to the view, and also to avoid the harsh light a little.
When I used my other Sony camera, the RX10 in conjunction with the Sony Playmemories 'smart remote control' software I didn't have any problems getting the results I wanted, but the setup with the RX100, for me, is not very intuitive.
Anyway, I set it up, and after hoisting it aloft I took a few pics using my phone as a remote control which I was fairly happy with.
On our return, I imported the pictures into Lightroom for editing and captioning and suddenly noticed that the ones from the monopod were missing!
It wasn't a big problem though as I had them on my phone didn't I?
Well, yes I did, but the phone had only saved them at a just over 1600 px on the long side, so, unfortunately, not good enough quality for stock sales, and this type of image is not suitable for upsizing as it would almost definitely fail Alamy QC, which would put me in the doghouse, and so far I haven't had a QC fail with them since my initial submission back in 2013 which was my first of 361 uploads to date.
The pictures below may look pretty, but the quality is only fit for screen viewing.
So, when you use the Sony RX100M3 with the apps on the phone, check and test to make sure you will be saving to the phone (I shoot RAW and JPG) and also make sure that the size setting for your phone is on 'original size'.
I never had any problems using the camera/phone software when I had the Sony RX10, but with the RX100M3 I even struggle with setting up my phone to the camera by wifi to use it, although that may change when I go back to Android... I'll let you know.
EDIT: Correct settings for saving full-size JPG to phone and full-size RAW/JPG to camera at the same time.
BEFORE connecting to the camera there is an option of copy image size on the phone version of PlayMemories... I choose original.
You can then connect to the camera.
After connecting with the camera, the full view of PlayMemories will be showing, then, choosing menu gives you more options including the option of 'size of REVIEW image'.
That is where I was going wrong.
I was assuming that REVIEW meant a preview size on the screen, it doesn't, it means that the file will transfer to the phone at whatever you choose, and I had the menu setting as 2M.
The image now saves on the phone as a JPG at full size and on the camera at my chosen settings which are RAW+JPG.
Edit December 2018, I have now changed back to Samsung and have a Samsung J5.
