Just a few minutes for a basic image, up to several hours for a precise positioning, exposure blending and crop to standard dimensions.

Right: Combining panoramic and sequencing techniques for this unglamorous image of pushing a bike on a too rocky trail.Ĭreating a full fledged panorama from a set of digital images can be as simple as loading them in the program, pressing and then. Even though I wrote my own panorama program 10 years ago, I currently use PTgui for many different uses: either to create full panoramas, or as an intermediate image alignment program. Just to say that the techniques involved have gotten greatly easier and with much better results since the time of scissors and scotch-tape. I've written at length about panorama images assembly in other pages of my site, so I won't do it again here. The blending option in the actually merges the colors without taking into account the burned/black areas
Also needs playing with the optimizer options. No, or limited to stacking layer and moving them manually to minimize the difference You just create a series of intermediate 'aligned images' before proceeding with the next process (HDR, focus extension.) For this purpose I use PTgui, a program meant for panorama assembly, but which can also align a stack of images. On the other hand, I've found that recent software is getting so good that it can handle handheld images with little or no additional effort: images are deformed to match properly and work fine if you have held the camera properly.Įvery single one of the methods I describe below require a proper alignment procedure. Images taken from a stable tripod by rotating the camera around its nodal point will need no or little deformation to match properly during the alignment phase. Special software is used to perform those feats.Īs usual with photography, and particularly panoramic photography, a tripod is a very worthy addition in every instance. The two main problems with combining images are the alignment of the images (so that lines and curves stay regular) and the blending (so that colors don't show sudden changes). Why ? There are several different reasons to want to perform image combinations: either to create an image which you cannot directly take with your photographic equipment (such as a widefield panorama) or to create a better image than what the equipment allows (for instance a higher dynamic range).

On this page I'll discuss how to start from several images and combine them in order to end up with a single, hopefully better, image.
