![]() As alternatives to PTGui, there's PTAssembler and PTMac, and a new freeware program called Hugin. When the images are a good match in all three channels, very minor tweaking with hue/saturation might be necessary to finish off.įor Panorama Tools, see stitching tutorial. It often helps if a temporary curves adjustment layer is placed above the images so that the contrast can be increased and shadows brightened. Use the curves tool to get the highlights, shadows and mid tones to match. See the tutorial blending technique for further details.Īs for getting images to match for colour and brightness, I find it easiest to match each of the red, blue and green channels of the psd file separately, viewing the images in b&w. If using the Photoshop stitcher, you can add the layer masks manually). (Panorama Tools will deliver the psd file complete with layer masks. The way to hide slightly visible seams in the sky is to feather the edges of the images using a gradient applied to the edge of a layer mask. There's also a plugin that can be used to correct images for light fall-off. It will correct lens distortions, give level and flat horizons, upright verticals, and enable multi-row stitching. Panorama Tools will also give far more accurate stitching than the Canon program. There are versions for Windows and Mac (and now also Linux). But if you want maximum control over your panoramas or are shooting them professionally, it’s hard to beat. I use Panorama Tools, together with PTGui (a front-end gui interface that greatly improves the user interface). PTGUI Pro’s user interface is another that falls into the functional but not pretty category, and there is a bit of a learning curve to get the best results out of it. ![]() Correcting seam problems is vastly easier if you use a stitching program that delivers a layered Photoshop. Then, the images should match reasonably well. It saves a lot of post processing effort if you give each image the same exposure and correct for vignetting before stitching. Seam problems like those in the image sample can be due to light fall-off/vignetting and/or variations in exposure. You could look at different Blend Modes before you In fact, instead of this you might have selected the sky entirely to start with and then pasted only the sky sections into their own layers and avoided touching the buildings at all. This will take a while to get right and there may well be a better way. If there are buildings or foreground that look terrible, our final step is to use the History Brush and paint over the adjusted buildings or foreground. Once you've done that, use your healing patch tool to clean up any visible joins you may have. Repeat the same steps for each layer and then merge them. Do another one across the entire pic and then go to edit>fade gradient (or SHIFT-CTL-F for PC) and drop the opacity to 60% or so - whatever looks right. To remedy this, make a layer mask (reveal all) and then drag a solid-to-transparent black gradient across the washed-out side of the pic, if necessary. This gets us a close match with the one side, though the side farthest from the seam will probably look washed out. PtGui has a sort of wizard: load the images, let it create control points automatically and done well, the first results I got were pretty bad and it took me a while to figure out why: The control point generation will look for distinct points that it can match in multiple images. Then go back to the RGB setting and, using centre arrow on the levels settings, fine-tune the tone for the seam. At this point we are primarily concerned with the sky and are ignoring the fact that the buildings may look worse as the sky gets better. Go through each colour channel and do the same thing. Match this shot as closely as possible to the main layer that we chose as the one whose colours we liked best, by sliding the arrows around (generally you'll just need to use the middle one). Now go to your red colour channel and open the levels adjustment window. Next, go to a layer whose seam butts up against this shot. It's a major pain in the butt to fix a shot after you've stitched it.įigure out which shot gives the closest representation of the scene i.e., the one whose colour you'll match the others to. You need to start with the pictures as separate layers in Photoshop.
