That is not a timelapse photo, that is a long-exposure photo. A long shutter speed was used. To avoid camera shake blur, the photographer most probably used a tripod or other form of support for the camera, rather than handholding, and may also have used a timer or cable release and/or mirror lock-up to prevent any jostling of the camera from the shutter ...


There is no video on this page. Just a single image. This image was made using a long exposure. Say 30 seconds or longer.


Purple is the welders glass remember welders glass is specially designed to protect our eyes not reduce light transmission as is a nd filter, and is also often seen when stacking cheap nd filters bought from ebay and the like as well.


I never tried it and would probably start with image stacking as opposed to one extra long exposure. In any case, take a look at IRND filters that are designed to filter out the IR spectrum from some 740nm. The IR pollution causes unwanted color shifts in the images. I don't know if these filters can prevent heat damage, another reason why I would use them ...


Long Exposure Noise Reduction takes a dark frame of the same duration to subtract the noise from the image. That's why there is a long delay; a 30-second exposure plus a 30-second dark frame plus processing time plus the time to write the image to the memory card. There will be obvious gaps in the star trails. If the gaps are minor, they can be corrected in ...


This is just the diffused light going through the welder glass. It comes from two sources: the sky and the two welder glass. (These have coplanar surfaces that allows for bouncing the light for long.) You cannot do anything with those either. You need to use optical quality filters (ND filters of high value) to achieve this effect, although then you will ...


that purple haze is probably a color cast caused by the glass itself; the welders glass often isn't neutral color. you should be looking at solar filters, or very dark (and probably stacked) ND filters. Thousand Oaks sells solar filters, to name one company.


Well you could always install "Magic Lantern". Using ML you could set a time for ur "Bulb" mode like 5min 10min etc. Then press shutter and go drink coffee, eat something, hang out etc and come back to have photo taken for you. I did a 5 min exposure without a problem with my old 7D I'd assume it'd be no problem for 60D. With ML you also get a lot of ...
