MDM posted a topic in Alamy Quality Control and technical talkAnybody like to discuss focus stacking - the process of taking multiple images of a subject at different focus distances from the camera and merging them on a computer to produce an image that is in sharp focus from front to back, something that is often not possible when shooting single images. We could share info on shooting and processing techniques, pictures (not necessarily on Alamy) and so on. I am relatively new to this and am definitely open to learning. I have done a few experiments a little while back but hope to do a lot more now with a lot more time on my hands with the Covid-19 isolation. It is a very suitable activity for those of us isolating in our homes at the moment as it is particularly applicable to closeup and macro photography where depth of field is typically tiny. However it can be applied to lots of other areas of photography as well such as landscapes. Everyone is welcome to join in from complete beginner to technical expert and hopefully we can learn and inspire each other.. Here is one of my first attempts: Orange and lemon
Refocusing without focus stacking?
hsessions posted a question in Community support: ask the forumSeasons greetings everyone! I have a question. First, I am interested in getting my hands on the Laowa 15mm f4.0 macro but the lens is not what I am asking about. I have watched a few videos in the Laowa Meeting the Macro Masters series and one in particular I have watched three times (in its entirety). Will be watching it for the fourth time today. In this video there is one thing I am not quite getting. Would somemone be able to explain, in very simple terms/for dummies what the photographer means. He is talking about an image he created which is not a focus stack, not a montage, but he talks about refocusing to get the right exposure etc. This word 'refocusing' is the part I am not getting and would really like to know what exactly did he do in camera with the settings for the foreground and background to achieve the resulting image, which he says is not a result of focus stacking. He did go on to explain he did the right exposure with artificial light (flash?) for the foreground and then changed the focus position to the background changing it to infinity and expose for the background. Straight forward stuff for all the Pros, but this is a multi-step process that I haven't ever tried. So any help will be appreciated.
