We’ve made use of Kuuvik Capture software for some time and Keith has reviewed it several times in the past.

The latest version V4.3 improves functionality, and now supports the EOS RP mirrorless camera which Keith reviewed a few months ago, which is now the main backup camera to his EOS 5Ds.

For many more details see the previous reviews and updates, which include detailed use of the split mode liveview and other helpful features.

If you’d like to know much more detail, there is a free e-book about the software

Using Kuuvik Capture for Canon EOS cameras

Kuuvik Capture has a few features, such as focus peaking and especially its multi-point live view option that still make it something I use for some tethered capture work with my Canon 5Ds and now the EOS RP, even as the free EOS Utility improves (I’d note it uses a lot less power than the Canon software – useful for times I’m using my MacBook Pro in the middle of a factory floor and can’t reach a power outlet).

There is a list of changes since V3.1 at the foot of this review.

My EOS RP is now supported (wireless as well), although not yet with RAW histogram support.

The RAW histogram (optionally) shows actual data in the RAW file (after shooting), as opposed to what’s there after it’s processed. [bright red spots are highlight clipping warnings]


Note here, how after white balance settings are applied, the R/G/B peaks which are some distance apart in the top RAW histogram are combined together in the ‘processed’ histogram in the Adobe 98 colour space shown below.


Where does this help me? Well, sometimes I’m shooting strong colours in less than optimal lighting – the RAW histogram gives me an extra tool in checking my exposures. There’s quite a bit more about this in the e-book for the software.

Split mode

One of the key features I use when shooting with tilted lenses is the ability to have up to three windows onto the live image coming from the camera. This makes accurate focusing a lot easier [see also my article about focusing with tilt)


What I’ve shown here is a small subset of what the software can do – if you’re curious, do read the e-book
