Sending photos from 3 camera to a laptop either IOS or windows, simultaneously wirelessly, is it even possible?

I have three cameras , a canon G11, a canon 7d and a canon 400d. They all have different lenses mounted on them. I need to take three different types of photographs from a subject by these three cameras. This for skin cancer photography, hence I need a normal photograph of a mole then a macro view of the lesion and then a dermatoscopic view of the lesion which requires me to have three different cameras at the same time to avoid changing lenses which can be quite time consuming. Now I was wondering whether there is anyway to send all the captured photos to a base laptop as I am taking photos. I have bought a wifi SD card for my Canon G11 already but the problem is that I cannot be connected to more than 1 wifi SD card at the same time.

I have read about the CamRanger here but I am not sure whether that is the solution or not? I appreciate any feedback.

  • \$\begingroup\$ Why is it necessary to tether them at the same time. At first I thought this question was going in the direction of needing to take the picture on all three at the exact same time but now I think you are just worried about lens changes. If you are just taking a single picture at a time is it not OK to just swap the cable over or use the SD cards? \$\endgroup\$

Use some EyeFi SD card that support the "EyeFi Cloud" Service:

From the website:

Multiple cameras. One experience.

Take pictures using any camera or smartphone you own, Eyefi Cloud will make them appear as one photo collection. Gone are days of manually merging together pictures from multiple devices. Eyefi Cloud does it for you automatically.

You should be able to use some SD to CF adapter, to use the Eyefi SD card on the 7D and the 400D as reported in the linked thread.

Note: this answer is just a suggestion, I've never tried the EyeFi SD card, nor the EyeFi Cloud service, nor any SD to CF adapter. Do your research before buying anything.

Also, as suggested by Michael Stum, it may be worth checking whether uploading pictures to a cloud service is permissible or not since we seem to deal with medical images.
