It requires fixed focus image stacks only with all the images aligned to each other, the way a microscope works. Originally designed for processing extremely shallow focus microscope images with fixed focus images, this is a Photoshop plug-in module with versions for both Mac and Windows. Two that are cross-platform are Focus Extender ( and Helicon Focus ( Focus Extender With this method, the magnification is changing as the focus point is moved.Ī Web search yields several extended focus processing programs, but few are available for both Mac and Windows. Variable focus imaging means that the camera is fixed in position with each image created by changing the camera’s focal point to move the focus plane through the object. Moving the camera with a set focus will maintain the magnification but it can be more difficult to achieve, depending on the camera used for the imaging. įixed focus programs require the images to be created by focusing on one part of the subject, then moving the entire camera forward or backward to place the focus plane at the next part of the subject. To make an extended focus image, a sequence of images, called an “image stack”, is created in one of two ways fixed or variable focus. When fed a set of images shot at different focal points, an extended focus program will combine the in-focus parts of each image together to produce a single image with an increased depth of field. ![]() This has now changed with the advent of extended focus programs. These adjustments can often result in the necessary exposure values going out of the allowable range for the scanning back, resolutions lower than desired for the final image, or exceeding the diffraction limits of the lens. In the past this meant the photographer had to move the camera further from the subject, change lenses or stop down to get more depth of field. The penalty for all this extreme detail is a much shallower depth of field in the image. Details which cannot be resolved with lower resolution cameras leap out at the viewer. It is absolutely amazing to do focus stacking! If you would like to try Helicon Focus click here.The extremely high resolution of the Better Light scanning backs can make some stunning images. I will also teach you how to easily fix mis-alignments post stacking! Large file batch stacking, “Batch Stacking” in Lightroom. In my focus stack, what I like to do is actually take the rendered stacks and merge those together and I will show you exactly how to do this. A lot of the times I feel that a particular method will work well with the soft areas of my image and another method will work better with the detailed areas. I will also share with you how to use several rendered stacked images as source files. Use your shutter release or timer so you don’t move your actual camera when you’re focusing macro. ![]() I will be rendering with method A, B and C and I’ll explain all of that in the video but just to let you know – you should really be on manual mode. Now, back to the INTERMEDIATE video for Helicon Focus, you will see that I will be rendering each image. I also have a blog post on focus stacking □ Check out that post too if you’re a newbie. If you can’t understand this yet and you haven’t seen my last video on the BEGINNER basics of Helicon Focus, then please check down below because you should watch that first before going beyond this INTERMEDIATE video. You take that photograph first and then you continually take one right after another, and making sure that you have at least one part of a section that is in focus on both images that you’re continually shooting. I’ll be in Lightroom but just a real quick refresher on stacking for Helicon Focus – the best way to actually photograph is when your subject is the closest to your lens. ![]() In the video above, you’ll see the images in red, those are the ones I’m going to stack. So let’s get to it! Make sure to open the video below! □ This video is for you that already understand the program but we’re gonna take you to the next level. Today we’ll dive into the INTERMEDIATE tools for Helicon Focus, so you can make, beautiful, world-class photography that you’re proud to share with the world. ![]()
