    GH5 SDR, HDR, HLG, color spaces, dynamic range

    Here is a very good study of different color scaces. http://www.tftcentral.co.uk/articles/pointers_gamut.htm It has an interesting table of contrast ratios.

    GH5 SDR, HDR, HLG, color spaces, dynamic range

    I made a simple test. I shooted a test image from my bright and vivid TV screen with GH5 10bit HLG and Natural contrast -5 / idynamic standard. Both recorded all the shades from black to white and primary colors from darkest to most vivid. HLG makes better image and less noise in shadows. My TV...

    GH5 SDR, HDR, HLG, color spaces, dynamic range

    HDR is coming and it causes confusion, fear and even anger in discussion forums. GH5 has a new HDR profile "HLG". It records more image data than normal profiles and even more than vlog-L. How large color space it can record compared to rec709, DCI-P3 or rec2020? Has someone used it with HDR...

    GH5 Paul Leemings New LUT for HLG Footage

    Thanks. How can this 12 stops of dynamic range video frame fit in rec709 space because rec709 allows only 6 stops of scene DR? You must clip the highlights if you want to call it rec709 video. When I show these kind of examples experienced film makers say "you cant do it, rec709 cant have more...

    GH5 GH5 internal audio vs GH3/4

    I have been wondering the Panasonic GH5 internal mic quality. It is odd that I cant find any test results for GH5 mic audio quality. Why testers are not testing audio? My GH5 seems to record low frequences much weaker than GH3/4. I must add bass very much when listening my GH5 recordings. (Wind...

    GH5 GH5 4k 8bit 60P much better than 8bit 30P

    I have wondered why I cant see macro blocking in my GH5 4k 60P file like earlier with GH4 8bit 4k 30P. I tested with complex motion and the result is surprising. 60P is much cleaner than 30P.

    GH5 Evaluating GH5 4K 10bit clips recorded at both 150Mbps and 400Mbps.

    Sorru. Difficult to make this post. I make it again. A static frame may break also if the i-frames get too little bitrate. It is like a bad JPG compression. I think GH5 static frame is a little tiny bit better in 150Mbs ipb than 400Mbs all-i. Here isan uncompressed png which show than GH5...

    GH5 GH5 new IS lock stabilator

    The new IS lock stabilator is incredible. It "glues" the lens in static clips but it helps in other ways too. Surprisingly the IS lock makes walking with camera very stable and smooth. It makes "floating" stabilization and keeps the frame balanced smoothly. Combined with DUAL IS2 lens and...

    GH4 Panasonic GH5 coming in 2017

    GH5 e-shutter in photos is slower than GH4. Dont take photos of moving subjects with e-shutter. This is odd because Panasonic says the new sensor is faster than in GH4. http://m43photo.blogspot.fi/2017/04/gh5-e-shutter-is-slower.html GH5 e-shutter seems to be as slow in JPG and RAW photos...

    GH4 GH5 Early Footage Thread

    Here are crops from the same 6k photo file opened in Photoshop at 16bit and converted to 8bit JPG. Looks much better than my versions extracted with Potplayer. I see no dithering.
