What is wrong about this pic? For that matter, what is right, if any? :rbounce:

Hmm.. you seems to use a rather big aperture size. I remember hearing from somewhere that you need to use a small aperture size in closeup to so that your subject can be sharper. It works well in your case. Did you zoom in your subject?

I guess the subject is relatively flat so the big aperture size did not affect the dof. I did not zoom in on the subject but my camera is very near to the flower. Almost touching if I remember correctly.

Thanks for all the kind comments. :gbounce:

Wow u can get to that close? Mine would have lost its focus if I am too near.

Falcon, for close-ups, larger aperture size is needed. Remember, aperture size is a reciprocal, f/22 is actually 1/22 and f/5.6 is 1/5.6. Hence, f/5.6 is considered a larger aperture size than f/22.

U-KnOwHo, QV-2900UX cannot zoom in so close, it's virtually impossible with such a camera and lens. You will have obtain a very very blur image if you took the shot that close to the subject. What you have here is a more than life-size replication, possibly 3:1. Unless, you zoom-in using the camera built-in zoom capability which is common amongst digital camera. So, please don't provide inaccurate information.

Lastly, it is a sharp and well-balanced shot. High in color saturation although flat hence lacking in depth.

I did not provide inaccurate information unless you are talking about the aperture part which is a mistake on my part. :embrass:

As for the closeness to the flower, it is true that my camera is almost touching the flower.

Lastly, it is a sharp and well-balanced shot. High in color saturation although flat hence lacking in depth.
Thanks. ;)

The Casio focusses to 1cm at 40mm. Furthermore, it's probably not 3:1 reproduction ratio (the CCD is really small).

Y L Lee, are you saying that the lens is only 1 cm away from the subject? And yet it can still remain in focus?

Agreeing, the CCD is small. However, that doesn't compensate for image capturing. All cameras (unless I am already backdated) works based on lens magnification. Most lens (unless really expensive ones) only produces 1:1 reproduction. Normally, extension tubes or bellows or inversing the lens with rings are needed to improve on these reproductions. Otherwise, use close-up filters to reduce the minimum focusing distance. Normal lens minimum focusing distance is 0.4m (40 cm), except for macro lens which are really expensive.

What I am trying to say here is that the CCD doesn't play a part in moving closer to the subject (what he said was he was nearly touching the flower). But it is possible with a digital zoom to magnify it once the image had been captured.

Please correct me if I am wrong as I don't want to cause any misunderstanding.

Otherwise, U-KnOwHo, sorry if I misinterpreted myself. No offence intended.

PS: I was (Still am) posting in the forums from photo.net and popphoto for a long while and it gets very disruptive when people provides inaccurate information.

Dun worry, Mouse. I am not offended. Words can come across as pretty harsh in postings which is why I use smilies. ;)

I am not so sure about the 3:1 and 1:1 you are talking about. Can educate this newbie?? ;p

Yes. My 995 goes to 2cm at 75mm.

You're thinking in terms of a SLR with a 24mm X 36mm imager. In case you don't know, the extremely small size of the CCD, means that even at 1:4 reproduction ratio, the image will fill frame. A couple of optical tricks here and there will allow the lens to focus real close.

agreeing, I just read the article from OutdoorPhotographer March 2002 issue. The Nikon Coolpix 5000 can focus at a minimum of 3/4 inches. However, he, Rob Sheppard, also mentioned that "...if you want optinum close-up,..., you need to use a close-up lens (a number of screw-in types...."

YSLee, if that's the case, I stand corrected and apologises to you and U-KnOwHo. :embrass:
