Hello, I have an Olympus E410 DSLR and want to take very long exposures of the night sky to get star trails. My camera has a limitation of a maximum shutter speed of 8 minutes when set to bulb mode. I have bought a remote for my camera so I can lock the shutter open. Seeing as I want an exposure longer than 8 minutes I thought I could take one shot after the other and combine them with software. Now the problem is after I take a long exposure shot on my camera it takes 5 minutes + for the image file to save and I can not take any photos until it finishes... Is there anyway around this so I can take a photo soonh after if not straight after the first shot??? Why does it take so long to save the file. The file size is much the same size as a normal photo and normally saves instantly??? Thanks heaps.
