    Hugin to stitch them and Flexify to manipulate them If you want to learn more about what a 360x180 panorama exactly IS head here and read the description If you want to get right into making these things keep reading This article is pretty long so if you want just the jist of things watch this video If you are serious and what to actually execute taking 360x180 panos then watch the video AND read the article By taking 360x180 panoramas and stitching them in certain ways the environments will look like little planets inverted planets or a number of other crazy things It does require some patience but it is definitely worth doing People will be asking you How did you do that every time you show them a 360 stereographic stitch You will need a digital SLR or even a point and shoot camera and a program called Hugin It is also recommended that you have a tripod with a panoramic tripod head and the Flexify Plug in for Photoshop but it isn t required I will talk about all of these in this article Taking hand held 360 panoramas First set your camera to take SMALL JEPGs You CAN take larger jpegs but I wouldn t recommend it until you are successful with your first completed panorama The resolution image size builds up fast when you are taking 360x180 panoramas Take your digital SLR and use the widest angle lens you have Mine is an 18 55mm kit lens set on 18mm Next point the camera to the ground and start taking pictures around you Shoot in vertical orientation Traditionally speaking it is best to use manual mode on your camera with manual focus and this is the method I recommend using but I ve discovered that using Aperture Priority mode or even full Auto mode with automatic focus works too If you are using Automatic Mode I would suggest your camera to be set on matrix metering Once you have the first row done move your camera up and take the next row of pictures making sure that the field of view will overlap by about 25 or more On my camera lens I have to take 4 or 5 rows of pictures with about 12 pictures in each row This comes out to be about 65 total pictures But that is on my specific lens and camera it might be different for yours If you re using a super wide angle fish eye lens you can get the job done by only taking 5 pictures The resolution won t be as large but hey it takes a heck of a lot less time Try to rotate your body around the camera rather than rotating the camera itself it s a good idea to keep the camera in the same spot Once your done taking those pictures you need to point the camera straight up at a 90 degree angle This is called the Zenith Then take another picture straight down at 90 degrees try to move your feet out of the way if possible This is called the Nadir I usually mess up on the zeniths and nadirs and that s fine but the image won t come out looking perfect There will be a little black spot where the zeniths and nadirs are supposed to be You will see what I mean if you didn t take these correctly it s not that big of a deal Now we are ready to stitch them all together on the computer Download a program called Hugin install it then boot that mother up Using Hugin to stitch 360 panoramas Load all of your images into the program Hugin will take a while to process all of your images depending on your computer speed and what size you took the JPEGs at this is why I recommended shooting small JPGs It takes about 10 minutes to process all of the images on my computer so be patient I would recommend closing all other applications you aren t using This will save memory usage which Hugin needs I ve found that if I had too many programs running Hugin would run out of memory and not do its job Once the images are done being processed one of two things will happen Either 1 A dialog box will appear saying that it couldn t stitch some images together and you need to manually fix them or 2 a preview window will pop up showing your panorama If the former happens you will need to add points on the images that are in the same spot on each photograph Hugin will tell you what images need this If it isn t possible to add points this usually happens with the zenith or nadir just delete the images and then re align the pano Now go to the top and click Preview Here is your image If you want it to look like a planet select stereographic from the drop down box Then when you are looking at the preview left click on the spot where you were standing to take the photograph This will morph the image into a sphere at that specific point And there you go You can adjust the field of view by using the sliders on the bottom and right side of the image but be somewhat conservative with this feature because the image will get distorted on the edges if you over do it You can also straighten the horizon by clicking that straighten icon at the top but I usually don t see any difference when doing that SIDE NOTE you can also optimize your image Click the Optimizer tab and select which parameters you want optimized This supposedly makes everything more perfect but doesn t always work substantially sometimes I don t see any difference after using it Remember to preview your image again if you use this feature Close the preview

    constantly blow wind onto your lens These things might not be necessary it all depends on how cold and humid it is Focusing Set your camera to manual focus and focus out into infinity Your camera won t be able to use Autofocus in these dark conditions Take a test shot to make sure your stars are sharp Exposure Time and ISO Now let s calculate the exposure If you are using one big long exposure and you re not combining a bunch of 30 second exposures take one 30 second exposure at ISO 1600 If it looks well exposed just take that 30 seconds and multiply it by 16 If you are using ISO 3200 multiply the shutter speed you used by 32 instead The number you get after multiplying the shutter speed you used for the test shot by the ISO you used for the test shot will tell you the shutter speed in seconds you will need to use when shooting at ISO 100 which is probably what you want to use when taking the actual shot Using ISO 200 should be fine when using that same exposure time too it will be a little brighter If you are taking a bunch of 30 second exposures and then combining them on the computer you don t need to do this because all of your frames are going to be 30 seconds Aperture What should the aperture be when shooting star trails It doesn t matter I usually use F3 5 on my 18 55mm lens White Balance Using anything other than AUTO WB will ensure a constant WB in each frame You ll need to do this if you are combining frames If you are doing one huge long exposure then it is okay to use Auto WB Using a Tungsten White Balance will make the sky a beautiful purple color Combining Multiple Star Trail Exposures Together If you ended up taking a bunch of exposures download the Startrails de program and run it it is pretty self explanatory so I won t go into detail here When you load your photos into that the Startrails de program will combine all of them nicely If you want to do this in Photoshop instead there is a special Photoshop Action available You can also do this in Photoshop by going to File Script Load Files Into Stack and then click OK Wait for all the images to load and then select all the layers and change the blending mode to Lighten Try experimenting with different blending modes Keep in mind that doing this in Photoshop might not come out as well if there is a ton of light pollution in the atmosphere You might need to adjust the curves and make all the images darker in order for it to work Secret Star Trail Tricks Fading Star Trails Over a long time you can rotate your focus ring out of focus so that each star gradually gets more and more out of focus This will create a cone like shape to every star Dotted Star Trails If you are taking a single long exposure put a dark object such as a hat or piece of cardboard in front of the lens to block the light from coming in Do this every minute or so Say about 5 seconds to exposure the light like normal and then 25 seconds with the object hanging over the lens to block all the light out Keep repeating this and you should get dotted star trails If you are using an interval meter then obviously you would just set the exposure time to 5 seconds and the interval to 25 seconds Try experimenting with different variations You could even make each star a different color in Photoshop in post processing Star Trails with Illuminated Foregrounds You can also use a flashlight portable speedlights car lights or a fire to illuminate a foreground object You can even illuminate entire landscapes at a distance if you have a powerful enough flashlight the LED Lenser X21 monster flashlight is my light of choice for doing this The first example below was illuminated by city lights just to the side of the hill and the second example was probably illuminated by a flashlight Star Trails with the North Star in the Center of the Frame In order to get the donut hole effect simply locate the North Star or just point your camera North Remember that stars rotate slower near the North Star so you will need to have your camera out a long time to get a good shot You can place your foreground objects right in front of the North Star This will have the stars circulate around your chosen object which is great for composition Parabola Star Trails It is the complete opposite if you point your camera away from the North Star The stars will go by very fast so you will get longer strokes in a shorter amount of time This was 130 30 second exposures combined using Startrails de If you have any other tricks send me a comment and an example so I can feature it in this article Happy shooting In order to prevent your lens from fogging up you can try wrapping up some hand warmers around your lens with a rubber band or get a miniature fan to constantly blow wind onto your lens This is tutorial blog post is just an excerpt from my Trick Photography and Special Effects E Book If you enjoyed this post consider getting the e book All the content you see here
