Once you decided what size your final image will have, at least in height and thus depending on what you want to do with it (fullscreen virtual tour or in a window), you'll have to redefine their size.

#PTGUI STITCH NADIR SOFTWARE#

Only one thing seems really important to me: all the images must have the same size in pixels or the panorama software won't want them. But really, you'd better work in RAW!īy image properties, I mean the size of the file in pixels and the extension format: JPEG, TIFF or PSD/PSB, etc. With that said and mainly if you stitch your photos using PTGui, it will be easy to ask the software to make a small correction, even if it hadn't been made before stitching.

Moreover, it is then very easy to harmonize a panoramic serial because all the photos can synchronize on the reference photo. Here again, you'd better make them on a 16 bits image, and better yet, if you want to work as well as possible, work in RAW. But as for luminosity, corrections can be necessary once at home, in front of the computer. One of the main assets of digital cameras is their setting of color balance before shooting.

Each overlap zone is marked.Ģ - once corrected, very easily by the way if you work with RAW files, especially in Photoshop's Camera Raw because since version 6.2, the final panorama is automatically free from marks at the level of overlap zones in the sky. So even if you're using the best panorama software, it is almost mandatory to remove vignetting BEFORE stitching.ġ - The photos have been Stitchd without correcting the vignetting. Indeed, a panorama which source images show vignetting can be spotted right away thanks to the darker vertical zones marking the junction between two consecutive photos as you can see in the images below.

The photos have been shot in 8 bits and in JPEG and this time, whatever the panorama software, we'll make the corrections on the final Stitchd image to go faster.īecause it is very visible in digital photography - maybe even more than in film-based photography - and because any panorama software has trouble handling for good reasons - they don't have any reason to manage it since each photo edge has the same luminosity - you need to make sure to correct vignetting BEFORE stitching. Several elements of answer have to be considered: Either we'll edit them one by one at that point, by lighting them up or darkening them with a Photoshop level for instance, either we'll do it on the final panorama hence with only one image.

HDR merging can be performed directly in panorama software like PTGui or old Autopano (Exposure fusion), without using specialized software: convenient!Įven if the first correction can be done directly on the final panorama hence only once, the second one, vignetting, must absolutely be fixed BEFORE stitching because panorama software can't do it for one good reason: they don't think! Luminosityīecause they've all been taken in manual exposure mode, all photos can have been globally over or under-exposed. You can usually remove the marks of the tripod directly in panorama software but I highly prefer doing it myself using Photoshop BEFORE stitching. Try to remove as many defects as possible like vignetting, chromaticism in your photos before stitching. The rest of this page is aimed at those who want to learn more. Here are the key points to remember about photo edits on the panorama. But to save time, it will be better to perform the others -levels, etc. It is also the case for vignetting as you'll see below. It is especially the case for optical distortions we'll see in the next page, completely dedicated to them. Indeed, certain defects that could appear on the final image are almost impossible to correct after stitching. It is the case, above all, to stitch both photos of the nadir or for openings and windows. Some photo edits or corrections must be performed before stitching the photos when you're trying to achieve the best final quality.
