All I want is a dSLR that, when I take a picture on the camera with its button, moments later, the image is in Apple Photos.

There used to be SD cards with built-in WiFi which could sync photos automatically, but the main player in that space (Eye-Fi) went out of business and I don't think anyone else has stepped up to make a version of that which works with modern cloud services. Not enough demand now that smartphones have obliterated the consumer camera market, I guess.

Project idea: figure out a way to cram an ESP32 into an SD card.

I used Eye-Fi for several years and enjoyed it. There was some opensource software to use it on a private LAN.

Searching 'wifi sdcard' and I found several vendors still making those cards, but I haven't used any of the newer ones.

all of the high end cameras have integrated wifi now

I was still able to pick up some Toshiba FlashAir cards relatively cheaply. No idea what the deal was, but some seller in India had hundreds of them for sale really cheap.

I have no idea what the original FlashAir software looks like. Never even occurred to me to try it—just assumed it would be a nightmare.

But it works fine in my old Nikon with PhotoSync on iOS!

Someone already did: https://www.aliexpress.us/item/4001119021440.html

This should be possible, it already exists for Google Photos: https://www.stg-uploader.xyz/

The Samsung NX1 and NX500 running Linux can be pretty easily scripted to upload JPEGs or RAWs to any online service, given that you have a Wi-Fi network with you. Unfortunately they are a decade old and rare on the second hand market.

I think canon DSLRs with wifi can ftp.

They can also connect to phones/tablets/websites but you need apps/services.

ftp direct from camera:

to be clear, that was not a random link, it was the link on the canon website

Yep. This is what I do with my r5. Connect to Wi-Fi network, configured to auto upload to ftp. Unfortunately no sftp support (but it will do ftps). It’s ok, but can sometimes be a bit unreliable.

What’s more annoying is that automatically adding geolocation data for photos requires a Bluetooth link to a phone via their app which seems pretty unreliable and sometimes messes up the ftp uploads. Older canon dslrs had built in GPS.

Doable with USB-C to USB-C cable from Camera into iPhone into Capture One app

Nikon Z series with Snapbridge are as good as you get on that front. They peer with WiFi or Bluetooth. You can actually remote control and view the camera with your iPad if you want!

Amazing work! Have you thought about doing a tutorial on how to do reverse engineering?

ge0rg5• 2 years ago

I hoped that this article provides enough information serve as a tutorial, actually. It's just skipping the parts that should be easy to google for.

Definitely comes across in the writing. Very step by step!
