![]() ![]() Use this mode is you want to make a post-production of the rendered file in a dedicated third-party software. The levels are available in the HDR mode and they let you make certain global changes on the panorama in order to reduce this dynamic. ![]() When passing to the HDR mode, the produced image often has a very large dynamic and we need to reduce this dynamic to have something that is displayable. In practice, you will not see the difference on a scene with low dynamics but everything changes when the exposure differences are very large. This method of correction directly calculates the luminance for each pixel Autopano no longer works with the pixel values, but works with the real values of the scene. The algorithm is different from the LDR mode and allows for the harmonization of panoramas when the differences in brightness are much larger. This mode is used when a subject requires a large margin of exposure. This icon is only available if your images contain Exif data for the aperture and shutter speed. The purpose of this adjustment is to align the small differences in brightness, contrast and color in the series of pictures that make up the panorama.įor the most part, this is the correction that you will use.įrom version 4.2, a new Exposure compensation menu will let you display overexposure (in red) & underexposure areas (in blue-not shown in the example) and choose the global exposure tone by using the slider. Warning, surprises could arise with the manual mode (automatic ISO, light conditions could change due to passing of a cloud, etc.). For example, when the picture is shot in manual mode. In fact, in certain cases, the color correction is not needed. In this mode, the mechanism to equalize the brightness or color of pictures against each other is not used. This example illustrate the vignetting effect (with special thanks to Jérôme Pouille) We introduced a new color correction engine that prevents vignetting and gradient. Correction anchors, on each image on the panorama editing zone:.You can't fix yourself Gamma correction manually but its value is always computed and applied Settings of the tool, in the tools zone ( from Autopano 4.2): Settings of the tool, in the tools zone ( Autopano 4.0.x): This tool regoups the global color correction and color corrections of individual images functions. The following tools are used to correct the colorimetry: You will also find a better white balance stability (see Color modes section below).ĭefault color space is sRGB and can't be modified 2.3 LDR Correction (standard correction)įrom Autopano Pro & Giga 4.2 we added a better support of large differences in exposure which gives much better results and let you choose the global exposure tone. ![]()
