The horizontal views should be set to 360 degrees.ģ. Press the 'Advanced' button and go to the 'Lens Settings' Tab. (Input any number for the lens settings)Ģ. Open up PTGui and load your equirectangular panorama by pressing the 'Load Images' button. It's quite involved, but in practice this is pretty fast and you can save the project and just drop in a new file later.ġ. That way most of the panorama won't have to be resampled twice.įor larger panoramas it might be faster to use the panorama stitching program PTGui to convert to a cube face and back. Do this on a copied layer so you can mask out the changes only. You can change the 'Latitude' setting to -90 and work on the top part of the sky, and then transform it back. The easiest way to transform HDR panoramas is using the Photoshop plugin Flexify 2 by Flaming Pear Software: Keep in mind that any conversion slightly decreases the image quality, so it is better to mask out the parts where you made corrections and layer it on top of the original (untransformed) panorama.Īnother utility which does panorama transformations is Bixorama. When you are done making your corrections, drag the corrected panorama back into Pano2VR and convert back to the equirectangular format. Simply load the panorama in Pano2VR, press the 'Convert input' button and select which output format you want. When you are done, convert the cubemap back to the equirectangular format and overlay the correction.Ĭonverting 8-bit panoramas is easy with the utility Pano2VR: In that case the best option is to convert the top part to a cube face so you can work on it. The equirectangular layout is pretty good for this, excep when you want to paint on the top part of the sky. There may be times when you want to paint in a panorama. This format used to be popular because it was easy to capture by photographing a mirrored ball.Ĭons: A lot of distortion and massive loss of detail Pros: least amount of distortion, small filesizeĬons: many seams make it hard to paint anywhere but in the middle of the cube facesīecause of the massive loss of detail in large parts of the panorama this format is not recommended for anything but lighting or scenes where the reflections do not need much detail. Often used in computer games because it has the most space efficient layout (and this format has hardware support). Pros: least amount of seams, no distortion at the horizon level.Ĭons: larger filesize, impossible to manually paint on the top of the sky due to the distortion. The most common layouts are:ĭefault layout of most panoramas, also the standard layout for most 3D applications. Panoramas come in many different layouts, each with their own advantages and disadvantages.
