Και η πρώτη E-mount κάμερα με 15.5 stop σε αισθητήρα HDR;!

Ξέρετε ποια είναι η επανάσταση που έρχεται στην εικόνα; Μαζί με το 4Κ, λέγεται HDR. Και μετά τις εκπληκτικές Sony A7II και A7rII όπως και RX έρχεται η a7000. Και τι φέρνει η APS-C E-mount κάμερα: η Sony A7000 όπως λένε οι φήμες θα είναι η πρώτη system κάμερα στον κόσμο με “on sensor HDR”. Δηλαδή με 15.5 stop σε dynamic range.

How HDR video recording works

To achieve true HDR video recording, the advanced Exmor RS camera sensor in Xperia Z changes the exposure every two lines of pixels. This creates a spatially varying exposure (SVE) array image, which is then used to make an image that is perfectly exposed in both dark and light areas.

To simplify the concept, for each frame the camera shoots one picture with two different exposure levels at the same time, one light and one dark. Then, an intelligent software algorithm is used to combine (synthesize) the two shots into one picture, pixel by pixel. This allows you to see the details of both the dark and the bright parts of the picture.

HDR for still images

With HDR for still images, the camera quickly captures the image twice with different exposure levels and stitches the two shots together to create one optimised photo. This way, HDR lets you capture clear photos even against strong backlight. HDR is automatically activated when Superior Auto detects scenes with strong backlight.
