This is meant as a way to gather information of how well the average person is able to take a photo at "slow" shutter speeds. It's not a professional test.
Volunteers should do as follows.
First, download a siemens-star here
. Then print it in A4 (8.3in x 11.7in) size.
Now, place the siemens-star at a distance of 5m (16.4ft) from you. It should be at about the same height as your head.
Set you camera mode to manual. For all the photos, use an aperture of f/8. If you do this indoors, you can adjust lighting conditions by opening/closing windows and/or changing the ISO setting.
Set your lens to a focal length of 70mm. There should be a focal length scale on the lens.
The shutter speeds we will use for this test are, in seconds: 1/60, 1/30, 1/15, 1/8 and 1/4.
If your lens has vibration reduction / image stabilisation, turn it off. If the camera body has it, turn it off also.
As there have been questions as to how you should position yourself, please see this video
. It's in spanish, but don't panic. At 1'40" it shows how to place your face next to the camera. At 1'58", it shows how to place your finger on the shutter release. Finally, at 2'10", it shows how to place your feet. These techniques will minimise camera shake and they seem a common way to take photos.
Take one photo of the siemens-star, for each of the shutter speeds I mentioned.
Now crop it so that each photo shows only the siemens-star itself and don't resize that crop (100% crop). Upload the photos to your preferred hosting service.
Post the photos on this thread, stating:
- Lens model;
- Camera model;
- Shutter speed for each photo.
Obviously, don't apply any post-processing.
The only way for this test to have any meaningful result is to have as many people as possible to take part. Thank you for your cooperation.
