![]() ![]() The first is a picture of the setup for the shot using a Canon M5 with an 11mm wide angle lense. Here are some shots captured near YVR on a Snowy day a few years ago. Occasionally, there is something in the field of view that might require more frames. Anywhere from 3 - 5 images in all for an extreme depth of field shot like the ice bubble photos shown below. Dependent on having foreground detail that I need/want to have in sharp focus, I would usually shoot 1 foreground image at a few inches, then a foot or two, then a few feet then mid range, and then distant, etc.In a landscape photo I would typically shoot 3-5 (or more) frames depending on the complexity of the field of view.In each successive frame pick an area where you tell the camera to focus very sharply on specific spots in the frame. Each frame should focus on an area that you can see the camera making errors in focus and correct.Your smartphone can also benefit from this approach and they are easy to mount on a tripod.While you can finesse things into level in your software, shifting 25 to 50 million pixels can alter the original and introduce errors! Best to make it level from the beginning. This is easy to do with modern DSLR cameras as they all have a built in level that is very precise. A very important step that I often see missed, even by pros, is to make the shot dead level.With the camera fixed in one spot (a tripod is critical) I shoot a series of frames ranging from very close, to very far away.By keeping to a consistent approach, I don't have to make assumptions about what I did in the field when I am back at my PC "in the digital darkroom". This is the method I use, based on training I got in an advanced landscape photography workshop that I will weave in here and there, and I never deviate from it.There is a graphic in the next post explaining this using the two photos presented above as examples. If you want to photo stack for infinite (well, at least really deep) depth of field, each frame taken in the camera should be in perfect focus for the focal plane you are planning that frame for. You also have some control over the process in the software as you are doing the stacking as there are many configurable options available as you do a stack. The software works better if each image is shot from an identical spot - that way the pattern matching is much more accurate and the algorithms are capable of masking out blurry areas and preserving sharp areas. Photo stacking is a technique made possible by what I call the "Digital Darkroom" provided by advanced photo manipulation and processing software such as:Ĭomplex AI algorithms leveraging masking, pattern matching and other techniques blend the various photos to produce an overall super sharp image. This thread is about correcting these things to give justice to the wonderful modeling people present on this forum. Here is another really pretty scene by but we can see how the camera let him down with the automobile out of focus, while the locomotive and distant cars are sharper! This shot can be done in a way that everything is in focus from the abandoned tire by the front porch all the way to the trees behind the locomotive. Tom made a good shot of a great subject, but the focus issues subtely distract and are obvious and solvable - so, how do we get the perfect image? Artificial Intelligence (“ AI”) algorithms built into better smart phone cameras do an amazing job, but even your favourite smart phone photos can benefit from a tripod and the techniques to be discussed here! No lense yet will provide infinite depth of field. For a lot of reasons to do with complicated light and lense physics, cameras compress depth of field far more than the human eye (our eyes do it to, but our brains compensate). In simple terms, Tom's camera let him down in one area: focus over the entire depth of field. The choices were almost subliminal, and in my mind, subconsciously decided by the viewers' brains' interpretation of focus in the foreground. ![]() He asked members which of two versions they liked. Recently, one of our Pinnacle modelers, Johnson took great photos of a fabulous scene on his railroad. ![]()
