Please look at this picture and let me know your thoughts on this.
Shutter = 1/20
F Value= 22
auto focus, used a tripod
Shutter = 1/40
F Value= 22
auto focus, used a tripod
But the 1st image seem rather smudged and blurry and the second image looks well defined with sharp edges. Any reason for this? Does this mean I have to use the flash all the time?
I opened a thread
for this yesterday as well. Thought it will be good to start a new thread.
Any help will be really appreciated.

Looks to me like there was some movement in the first picture, caused maybe by the pressing of the shutter button or movement in the tripod.the flash has taken care of the second shot because the exposure is made at the flash duration which is a lot quicker. you dont need to use flash all the time if you keep movement out of the equation.try retaking the first shot making sure that all tripod mounts are tight and use either remote release or your cameras delay timer so that you are not in contact with it it at the time of exposure. Hope this helps - Graham
Looks like camera shake to me Did you use
1 sturdy tripod
2 remote release / timer
3 tripod on a sturdy floor
4 tripod not in wind
All above can effect camera shake
Yes, I think Graham has hit the nail on the head.
Camera shake - or a moving subject. the flash as simply frozen the motion at the intatnt of the flash.
Ensure that every bolt on the tripod is done up tight. If you have rasied the central column, try lowering it again.
Also try the mirror lock-up.
Once you have applied all of the above advise, here is something else to look into, All lens have variations to some degree, And what this can mean is that they have a sweet spot in terms of Aperture and OR Focal length, You might find for instance that your lens has a sweet spot regarding the Aperture at let's say f16, And going to f22 there is a drop off ( That's only a for instance example ).
Thanks for all the advice everyone. I will implement this and see how it goes. Plus I find Vince's comment particularly interesting.
yes, sharpness does usually drop off at F22, but not really this much. And anyway, both samples were taken at F22
First one shot at half the shutter speed of the second probably a bit of wind or motion when pushing the shutter. Why use f/22 for that subject by the way?
Quote: probably a bit of wind or motion
I quite often have trouble with a bit of wind, but I only get motion if I follow through...
My coat's already on ;0)
This image from crop with large size or you shot it as it is? If you shot as it, try to decrease ISO 200 to below 100 or equal to 100. I'm not sure why you used f/22 for this image. I know everything is compile by anyone with their own needs... May be you wanted to get anything else in the details... Anyway....
If your camera supported MACRO then turn it on. This object during shoting at the top of the water or on a surfce? If water then put it on a surface, then use tripod, and hope in your room there is no wind If yes, then plz try to closed the window... Its really cool outside...
Further, you don't need to use Flash in every image, where its require use it, do not use every where... Also decrease the flash lights value with camera own setup tools or use fabrics or papers to decrease your flash light...
Hope this will help you.
