NOTE: This image is a focus stacked image of "Sony Alpha 7R IV rear view from elevated position, display extended.jpg" consisting of 15 images that were merged using Zerene Stacker Version 1.04 Build T2021-02-16-2045 (licensed). As a result, this image underwent digital manipulation which may have included blending, blurring, cloning, and colour and perspective adjustments. As a result of these adjustments, the image content may be slightly different than reality at the points where the images were combined. This manipulation is often required due to lens, perspective, and parallax distortions. العربية ∙ Deutsch ∙ English ∙ español ∙ français ∙ 日本語 ∙ македонски ∙ português do Brasil ∙ русский ∙ slovenščina ∙ ไทย ∙ українська ∙ 中文（简体） ∙ 中文（繁體） ∙ +/−
