1. This is a simple demonstration of the crop factors for three generations of the Panasonic GH camera: the GH2, GH3, and the new GH4. This comparison shows that there's a larger crop factor for the GH4 in 4K mode than when in 1080 mode. It also shows that the GH4 in 1080 mode has the same crop factor as the GH3. And finally, it's a reminder that the GH2 still has the lowest crop factor of all these sister cameras.

    I used a Voigtlander 25mm set to f2.8 on each camera. I used the same locked-off tripod position for each (apparently I bumped the tripod in between the GH4 and GH3, resulting in a slight pan to the right).

    Camera Picture Profile Settings
    GH4: Cine-D -4, -4, -5, -4, +0 with a Highlights/Shadows anti-S curve in Lumen space 0-255
    GH3: Natural 0, -3, 0, -5
    GH2: Smooth -2, -2, -2, -2

  2. NOTE: Higher encode version at vimeo.com/54933257 and youtube.com/watch?v=3C1o9_sB87Y

    300mb - 5000Kbps - mpegstreamclip transcode B version. Notice the reds are over saturated in this encode.

    Some more scene testing and slow-motion conforming on a 1080p timeline. This was output as 9Gb ProRes 422 file and transcoded once more to mp4 using mpegstreamclip at 5000Kbps ceiling mode (300Mb file) as FCPX kept failing to upload the estimated 1.5Gb h264 file direct to Vimeo. I will endeavour to keep trying to upload the original as the colour differences are quite large!

    This was shot at one of Brighton's famous lanes, Kensington Gardens.

    A test of the GH3 with a 70-200 Canon L lens which effectively doubles for M43 (140-400m) at f2.8 (wide-open on the adapter), 200ISO, 100 shutter.

  4. When on a recent shoot in Shanghai I popped into the Arts Department at the University to grab some shots for another project we are working on. I only had an hour there! Here is a very short montage of some of the footage I gathered. As always very happy with the footage, esp when you consider how easy it is to pop this little diamond into your rucksack! These are my settings (which I always use now):
    Contrast: -5
    Sharpness: -2
    Saturation: -5
    Noise Reduction: 0
    Recording at MOV 1920x1080 - 25p - 50 mbps

    The one thing the GH3 does is have very deep blacks, even when you try to ‘up’ them in the settings by keeping the CONTRAST at -5, but there’s not a great deal you can do about this. My advice is you are better over exposing slightly as It’s easy to bring the levels back ’down’ – as opposed to having to ’lift’ them. It's amazing what information is stored in the picture on this camera, bring the highlights down in edit, and bring back all the detail!

    It's such a super little camera, and a must have for any cameraman.

  5. I documented one of my best times in life so far with my small Panasonic Gh3 camera. This trip was ment to be the final chapter of my academic career entering the workers world. It gave me lot of time to think about different things and get influenced by what the world gave me. In 88 days around the world.

    Thanks to Justin Grimaldo for this epic voiceover.
