I assumed photos would go in Pictures. I can't find them. Where are they? Does only 1 get saved into the dash_app directory? Can't I do a time lapse or save a favorite sunset? Thanks Wallace

W,
Only one gets saved at this point. HOWEVER, For V024 of SkyWeather2, we will be adding a time-lapsev ideo on a revolving 28 day basis built on the Raspberry Pi locally! And accessible through the dash_app. You will be able to save them from there.

Any suggestions for improving quality of early and late day photos? Also either long exposure star night photography or if not just skip black exposures?
Anyone tried HD camera or a lens hood?

W I have actually put a great deal of thought into the early/late day photos but for a different project. What I may test in mine is to use the lux value from the WeatherRack2 to determine the exposure mode, shutter speed, and ISO. The only problem with long exposures during the evening is clouds, rain, and fog. Long exposures on cloudy, rainy, and/or foggy evenings look bad. Jason

I have temporary covered the camera with a toilet paper tube. It really helped with the blue led which couldn't be turned off. I will replace with a short pvc pipe once I get it notched.

Have you tried a small piece of electrical tape?

I'm happy with the tube. W

What I may test in mine is to use the lux value from the WeatherRack2 to determine the exposure mode, shutter speed, and ISO. Jason I saw your post. I like the flower pot idea. I ordered the clear dome but couldn't find the automated camera mount that Dr John mentioned in an earlier project thinking with the two I might be able to do some AI with camera pointing. MouseAir was a not a very practical project but it was great for getting me thinking about AI. I need to maybe create a lens hood to help with afternoon glare from the west or move the camera. Do you have a python library for camera management in mind? I was starting simply by not saving photos after a low lux value so the last visible photo would remain. I was disappointed I didn't get an night shots when the moon was full. It was bright enough to wake my wife with the blackout shades closed just what came in around the edges but the default setting on the camera was black. Wish we had Dr John's wisdom on this. I bet we could borrow from MouseAir and instead of identifying cats train for certain photo aspects or to seek light sources either to avoid the sun or redirect to moon and stars at night. I bet we make it discard the cloudy ones you mentioned. I backed a kickstarter with a bad ass telescope but it is over a year away. I have even considered the HQ camera mount. Maybe Dr J will add his thoughts. He had mention that Sky2 V024 was going to save photos locally but I really think so much more is possible. W

I like the idea of saving the last image before darkness! I’m gonna noodle on that one. Regarding afternoon Sun, you’ll likely be able to minimize it by pointing your camera to the South.
I use picamera because of the Python interface but raspistill will do the same thing from the command line. Pillow has some limited analysis capabilities for evaluating the captured image before saving it. OpenCV would likely be the tool that would be required for any deeper analysis of the captured images.
Regarding the sun and moon, the easiest solution would likely be to use an online API that reports position information for a geographic location prior to capturing images. A two servo motor camera mount with a fixed base could be used to manage the position of the camera.
Thanks,
Jason
