mickfly Posted March 11, 2021 Share Posted March 11, 2021 This is the latest on the Alamy Content Twitter feed.. "Top tip: If you want to photograph stars at night put your camera on the widest f/stop possible and shutter speed at 20 seconds. If you want a light trail, increase your shutter speed. Try changing your ISO if the shot's still too dark" Really Alamy?! 1 Link to comment Share on other sites More sharing options...

"If you want a light trail, INCREASE shutter speed". (should be decrease shutter speed) Why are they trying to give very simple 'tips' to what should already be good photographers?

Which is correct for star trails. Edited March 12, 2021 by spacecadet Link to comment Share on other sites More sharing options...
mickfly Posted March 12, 2021 Author Share Posted March 12, 2021 (edited) Increase the time the shutter is open by reducing shutter speed is correct, which is not what they said. Tips are meant to simplify things. I'm not being pedantic, they were questioned on Twitter and answered it badly.

MDM Posted March 12, 2021 Share Posted March 12, 2021 This demonstrates how much confusion can be caused by loose terminology. I agree with Mick Flynn if the term shutter speed is taken literally although I can understand what spacecadet is saying. The real problem here is that whoever wrote the tip did not think it through, moreover given that it is aimed at novices it would seem. The advice to increase your shutter speed is at best confusing as it is completely ambiguous. Taken literally increase your speed means go faster or in other words use a shorter time. Experience photographers will know what was meant but that is not the point. It should have been stated as “use a longer (or slower) shutter speed”. Then it would be completely unambiguous. I have seen the confusion over this when explaining the concept to novices. Aperture is worse again. Fundamentally and this is being pedantic, the term shutter speed is actually incorrect anyway, it should be shutter time. . 2 2 Link to comment Share on other sites More sharing options...

Or anyway that's what I would understand. Edited March 13, 2021 by geogphotos Link to comment Share on other sites More sharing options...
