![]() When you eat at an Indian restaurant and order your roti (chapati, shabaati, safati, rotli, phulka, or roshi - brilliant ideas seldom stay confined to a single culture), you are doing so in the full expectation that there is someone in the back who knows how to turn those humble ingredients into something magical. The ingredients are whole wheat flower, a tiny amount of water, and an even tinier amount of oil. The bread is indescribably delicious and to be appreciated fully it should be eaten the moment it is pulled from the open flame of the burner when it is still the size of a cantaloupe, a crisp and chewy charred ball filled with aromatic steam, and nothing else. There is a type of bread enjoyed daily by millions across the Indian subcontinent and around the world. ![]() So if these are such competent stackers, and they are, why aren’t we using them? To understand that, an analogy is in order. ![]() At the current time, there are two commercially available, affordable, stacking products that offer all or most of the required functionality and an intuitive graphic user interface Helicon Focus and Zerene Stacker. So the technical challenge should be self evident - how do we blend these one thousand partially focused images into one fully focused one? We need a sophisticated focus stacking software program to do the heavy lifting. Let that constraint sink in for a moment - to build a composite image of a subject one millimeter deep, made up of images that are all in sharp focus, would require that the camera or subject move roughly one micron between capturing each of a thousand individual frames. At a magnification of 20X, for example, our depth of field is only around 2 microns, or 2 thousandths of a millimeter. dng file, I believe.The primary difficulty in capturing high resolution images of very small subjects using photographic equipment is a result of the very shallow depth of field at which we work. jpg (.jpeg) The first three will allow full processing capability and will retain 16-bit pixel depth. I thought the D850 has that feature build-in (no software needed), but one can always do it the old fashioned way and use PS! I also think that Helicon deals with focus breathing a little better, plus it provides a 3D model of your image should you choose to generate one. But I do prefer to end up with the single raw (dng) - it is a faster and easier workflow. What I do when I use Lightroom/Photoshop is to open the raw files, edit a representative image in a stack sequence, then sync the edits. It is nice to have the flexibility to adjust the stacked images, rather than to adjust each component image. The PhotoshopL/Lightroom solution forces an export to a raster file (bit mapped), where each individual image is added to a single image file as a layer. You can stack your unedited raw files into one image, then edit the resulting dng file in Lightroom or Adobe Camera Raw, or any other software that can read a dng file - as a single, camera generated raw file. I am concerned that once you stack Raw images you wont be able to process to the same degree.? I tend to process my Raw files using the DXO and love the changes I can make to end up with a great looking photo. I am not sure if you need to process all the Raw files first then use the Jpegs in the stacker program. My question is what is a good software for stacking landscape images which I take with the D850.Ĭan you use the Raw files to create a new raw file and then be able to further process afterwards using the DXO software. I currently use DXO Photolab and love it, I also have Corel Paintshop Pro 2018 and use it very seldom. My question is about a suitable programme for stacking the Focus Shift images into one. I love this site, lots to learn from you all.
