Caveat: krpano is an excellent panoramic viewer that is sold at a reasonable price and is supported by Kolor's Pantour software products. I would advise people to use this viewer unless they do not have a budget or have a high desire to use freely available software. I have provided links to two oth...

Photoshop file saving single threaded w/ compression

Hopefully Adobe will multi thread saves and allow you to turn off compression which would make the tas...

It is always difficult for me to make the compromises between ISO, shutter speed, aperture value at events where you will not have another opportunity. You definitely need time to take some test shots. Though one very important rule is to choose settings that will make the most important part of the...

1. You can use the settings->optimization tab-> multiple viewpoints checkbox . I have used the 1000 mm trick in other stitchers, but APG has yielded better results. I will need to try the very large focal length to observe any improvements. 2. You can create another folder of reduced resolution imag...

1. It is important to manually set the white balance, ISO, aperture, and shutter speed to obtain consistent exposures. There are additional camera settings in some cameras menus that may override your manual settings, so you need to learn more about your particular camera settings to ensure that the...

You should attempt to limit the deviation in exposure and white balance by carefully checking your camera settings and not being too ambitious with the choice of the focal length when lighting is not steady and changing. Though you can repair this panorama using different methods. 1. Use the Adobe P...

1. You should look at Gene Coopers amazing linearly captured macro work at http://www.fourchambers.org/ He uses Autopano Giga to process his focus stacks and stitch. 2. Helicon focus can automate your capture work. You leave the lens in autofocus mode and set the range and step between photographs. ...

1. If you are using OSX you can do a command line cd, mkdir dehazed, and mv of all of the _dehazed files to another directory. The command line tools provide you with an efficient way to do this versus using the gui. 2. If you are using Windows, you can download Cygwin and use the unix based shell c...
