The average color of the New York City sky, updated every 5 minutes.
- Wickk 15y agoInteresting. Not sure why this on the front page unless I'm missing something very important, but interesting
- rrrhys 15y agoI like it because it is different (Inspiring maybe?), and it is someone's hacky project. Maybe a bit simple, but fits in IMO.
- crocowhile 15y agoIt is on the front page because it got a sufficient amount of upvotes in a short time.
- HoyaSaxa 15y agoPretty cool. Might base my next color palette off of this.
- reustle 15y agoNo API?
- sjwright 15y agoA clever idea, however his data source is irrevocably corrupted by the auto exposure and auto white balance of his webcam. The result is, sadly, more influenced by the algorithms in his camera than the sky itself. Notice how there's some outrageous and short-lived tones during sunrise and sunset -- that's the white balance jumping around (Possibly an automatic saturation gain too?) Then notice how the brightness doesn't peak and fall during the day, instead jumping quickly from darkness to "full" brightness with frequent dramatic shifts far greater than reality would allow. That's because the moving cloud cover is triggering the auto exposure to jump around incessantly. The ideal fix would be to replace the webcam with a digital camera capable of tethered shooting and fully manual operation. You'd fix the shutter, aperture and ISO values to a level that minimizes clipping, set the white balance to daylight, and point the camera in a direction least likely to be in the sun's path (in the southern hemisphere, that's south). In order to capture the dynamic range fully, you could allow the camera to automatically choose the shutter speed, then compensate in the algorithm by reading the shutter speed from the EXIF data. That said, full points for the idea, and for a great web app to visualize the data!
- seabee 15y agoSome webcams have manual settings, I know mine does. Just enabling those should get you 90% of the way of a tethered digital camera, "all that remains" is getting sufficient dynamic range and fixing the curves/compensating for human perception.
- sjwright 15y agoMany cheap/consumer devices let you disable some automatic adjustment, but rarely do they let you disable everything. For example, I've seen webcams that can fix the white balance but have automatic saturation adjustment that can't be turned off. The cheap option that comes to mind would be an old and/or second hand Canon PowerShot capable of running CHDK firmware. Ask friends and family; you'd probably be able to score one free from a dusty cupboard draw.
- sneak 15y agoGood insight... but New York City is in the northern hemispshere.
- sjwright 15y agoYeah, which is why I qualified it. I assume it's the opposite and the sun drops to the south in a northern winter, but I simply don't know if my assumption is right.
- sp332 15y agoYup, I live in northeast USA and the sun has a distinct southern slant even in summer. In winter it hardly gets over the trees.
- joshwa 15y agoNotice how there's some outrageous and short-lived tones during sunrise and sunset -- that's the white balance jumping around (Possibly an automatic saturation gain too?) The ones at sunrise are weird (blue throws off the white balance) but the sunset ones are actually accurate-- that's the color of a NY sunset in the summer. Surreal, eh? I miss New York.
- arethuza 15y agoIf the size of each block was reduced to a few pixels square you could fit an entire year in a single image (4 pixels * 12 * 24 = 1152 wide, 365 * 4 = 1460 high) - which might be nice way of visualizing what the weather is like in a location.
- sjwright 15y agoIf you were making the blocks that small, I'd make the axis meaningful and go 365 blocks across -- one column for each day of the year -- then midnight to midnight from top to bottom. This would be a great visualization of daylight quantity and quality over the year.
- shashashasha 15y agoA similar visualization to what you're talking about is an old project by Lee Byron: http://www.leebyron.com/what/daylight/ http://www.leebyron.com/what/daylight/
- arethuza 15y agoYeah - that's similar to what I had in mind, I don't know if making it bigger would show the effects of weather more. What those do show is: - The huge variations in day length due to latitude - How those of us in higher latitudes spend in the gloaming - my favourite time of day
- stoney 15y agoWhen I used to work in building design, I used to create lots of charts of various climate data for projects in new regions where I didn't know much about the climate (and also for eye candy in presentations). One of those charts was very similar to what you suggested. Basically a 2D array of coloured squares, with hour of the day along one axis and month of the year along the other. Then each square would be coloured according to the average solar radiation falling at that time of day in that month (using a blue-green-red type scale usually, but you can do grey scale or anything else you can think of). It was a useful way of visualising lots of stuff - variation in day length, strength of the sun, summer/winter variations, etc. You can plot other variables like this too - temperature, humidity, ...
- mmaunder 15y agoBrilliant idea! The site is a little slow, so in case it didn't work for you first time, mouse over each panel to see the actual photo that was used for the avg color calculation. I'm often looking for color inspiration, so will use this. Would be amazing to have this for Colorado skies, especially as the sun sets over the Rockies.
- rads 15y agoThe average color of the Seattle sky, updated every 5 minutes: #DDDDDD
- zachrose 15y ago#DEDEDE every now and then when a Boeing plane flies over the camera.
- georgefox 15y agoIt must be hard to sleep at night with all that light.
- AndyKelley 15y agoI'm moving to Seattle in 2 days - looking forward to it, although I'm going to miss Mr. Blue Sky. http://www.superjoesoftware.com/temp/tempe-temperature.png http://www.superjoesoftware.com/temp/tempe-temperature.png
- jish 15y agoShould totally add thumbnails. The mouseover would be more convenient for users and bandwidth costs would be lower.
- jish 15y agoOr maybe they already are thumbnails, and the site is suffering from the Hacker News effect... =o
- phatbyte 15y agoIt would be pretty cool if he it make his could available on github so others could do the same at their cities.
- chanux 15y agoI looked around. and found this http://jsfiddle.net/xLF38/ http://jsfiddle.net/xLF38/ Hope it's helpful. a bug fix: `document.body.style.backgroundColor = 'rgb('+rgb.r+','+rgb.b+','+rgb.g+')';` should be `document.body.style.backgroundColor = 'rgb('+rgb.r+','+rgb.g+','+rgb.b+')'; `
- rorrr 15y agoAt which color balance though? If it's auto color balance, it's completely useless.
- matmann2001 15y agoI'd love for a way to interface with this site. Perhaps something that let's me get the current color and update my website's background color with it.
- joshwa 15y agoI always wanted to make a wall-sized version of this with really bright LEDs-- kind of like a light therapy box, but programmed with the full progression of color and brightness of various locations and seasons around the world - summer in NYC, Paris in the springtime, New England in the winter, LA on a non-smoggy day, etc., with options for real-time data feeds, too. So you could feel like you were in the best location in the world on the best day of the year. Or just synchronize your work/sleep schedule with some other timezone. Small versions as nice gifts, big custom versions for the luxury/institutional market. Chumby app. Wall mounted LCD/LED and/or LED dome projection. Any hardware hackers feel like pairing up? I'm a short flight from Shenzhen. ;)
- JonnieCache 15y agoYou could definitely sell these I reckon.
- barmstrong 15y agoClever idea - I think it would be even better with some thinner lines (either vertical or horizontal) like http://moviebarcode.tumblr.com/ http://moviebarcode.tumblr.com/ This would more closely match the progression of time, instead of making rows of squares.
- ZackOfAllTrades 15y agoThat looks terribly depressing to me. Just saying.
- tanay46 15y agoGreat idea. Its already gone viral :) It might be better if you provide thin strips of each color rather than whole thumbnails as it can more accurately tell hows the skys colors is changing
