A tip to help get Sharp images RSK Gold Star Critiquer/Gold Star Workshop Editor/Gold Note Writer [C: 1089 W: 589 N: 1943] (14753)::2010-03-30 12:52
The following tips for helping take sharper images is from this magazine 'Digital SLR photography' a British publication,which I find gives helpfull tips to improve ones level of taking photographs,if of interest try out their website www.digitalslrphoto.com.

Taken from the above publication.
People usually get blurred photos due to slow shutter speeds. Shutter Speed > Focal Length NR. If when you use faster speeds your photos are to dark,simply choose a wider aperture [ Smaller F/* number ] or/and Higher ISO number.

18mm-28mm Lens use 1/30
35mm " " 1/30-1/60
85mm-100mm " " 1/125
135mm " " 1/125-1/250
200mm " " 1/250
300mm-400mm " 1/500
600mm " " 1/500-1/1000

Hope this information is useful to some of you.
Cheersd

Sorry, this is information is far from complete and could lead to incorrect conclusions. For example a wider aperture will give you less DOF and therefore more OOF areas.

It is better to know what shutter speed, focal distance, focal lenght and aperture do to a photo and use this knowledge to create the photo you want to make. Sometimes this will match shutter speeds as suggested, but sometimes it means you will need to use a tripod or any other form of support.

Just making photos fully concentrate on shutter speed won't bring you far.

I agree with Niek

Usually its known as "RULE OF THUMB" i.e "shutter speed = focal length" and that is used to avoid camera shake only. The DX bodies crop upto 1.5X(Nikon) 1.6X(canon) and 2X(Oly) we should make sure what is the effective focal length in such cases.

Hi Niek,
would you agree or disagree, that the information given, would assist newcomers to photography, who are just beginning their first steps in using a SLR handheld,until they become more knowledgeable, of this art form photography? It was not meant as an aid to members of your standing & knowledge.

Hi Ron,
Of course it helps, but it could also help in a wrong direction. I think a better explanation would have been helpful. Something like:

If you shoot handheld, be sure to stay close to the following shutter speeds whit the lens you have.

I agree,thanks for clarifying it, Niek.

In addition to shutter speed here are other basic tips:
-Use Tripod
-Use Cable, or remote release, or
-Shoot with time delay shutter release (2 sec)so you do not move the camera
-Lock mirror
-Make sure your sensor is clean.
-focus carefully.

As SunToucher tips, to get the shutter speed closer to the focal lenght, is a very good advice, that the way I was thought and with experience, I found out, that it was right. But since, the focal length on reflex camera, has changed. sensor versus film plan. You must increase speed, in order to avoid camera shake, or mouvement.

And tho sharpeness, and focus, works hand to hand, you don't want to confuse the two, they are two different things. Raw files, will be less sharp..and often need some more adjustement in post process.

Sharpeness may varie according to the lense you use...some will give you sharper result.
While sharpening will decrease contrast, between pixels, you don't want to overdo it either, better use a smaller aperture, then over-sharpen, which will give you "stair" and a grainy image.

Good to use a tripod, make it a stirdy one...those cheap one demand more attention.

Got to be extra carefull, specially doing close up.

Denis,
Only the focal length of APC DSRL are changed. (Nikon 1.5x Canon 1.6x just to name two brands) I am using a full frame DSRL so the focal length on my camera has not changed. So to conclude, it is important to know the crop factor of your camera and use it in your calculation for the minimum shutter speed for handheld photography.

Those numbers only works for 35mm old argentic support camera. Unless your sensor has the same size, that the FX camera offers; those number don't work. Most of the time, you'll have to increase the shutter speed, for DX format.

That is just what I wrote, only not in Nikon language but in a more general language. the DX is a APC DSRL with a 1.5x crop. The FX is a full frame DSRL equal to the analog 35mm.
