Butterfly Universe 賞蝶天外宇 – Ancyluris aulestes

Yesterday, I shared the low profile Satyrinae butterfly.  Today, let us take a more eye catching Riodininae.  Ancyluris aulestes was showing some dazzling blue color under the sunlight.  It was recorded in the Amazonia within Ecuador.

昨天分享了不起眼的高海拔眼蝶. 今天來一款華麗一點的蜆蝶. 這Ancyluris aulestes, 在陽光下就會閃閃發光, 攝於厄瓜多爾境內的亞馬遜林區.

Butterfly Universe 賞蝶天外宇 – Altopedaliodes tena

This Satyrinae butterfly was not really eye catching.  However, it was recorded on the way to Amazonia from Quito.  Out of my butterfly gallery, this is the record that was taken at the highest altitude (about 4200m).

這眼蝶並不漂亮, 可以說是毫不起眼. 不過這是在厄瓜多爾首都基多前往亞馬遜林區時. 在我拍的眾多蝴蝶之中, 這是最高海拔拍到的紀錄(大約是海拔4200m).

First Field Test of Panasonic GH4

Previously, I created some high quality 4K video clips with Nikon V2 camera.  While the buffer depth of Nikon V2 was 60 frames regardless of frame rate, it could not be used for shooting continuous 4K video.

Now, with Panasonic GH4, I can shoot 4K video directly and continuously.  The workflow is clearly more convenient than shooting with Nikon V2.  Quality-wise, the RAW photo based video from Nikon V2 was unbeatable.  However, the compressed video format of GH4 offers a clear advantage in lower consumption of storage space.

GH4 records 4K video in the consumer grade YUV420 format.  That mean, the video contains full 4K monochrome video with color information in full HD quality.  It may not match those broadcast grade 4K products, but the quality is respectable.  The bottomline is, you will get nearly flawless video and significant improvement over GH2/GH3 on full HD monitor.

Here is a demo clip I recorded:
