I remember reading answer to this in Bryan's excellent book Understanding Exposure. Question is answered on Page 53. I will state what he says:

When shooting story telling compositions in which you want as much front-to-back sharpness as possible. I'm often asked by students, "Where should I focus" ? So here's my foolproof "formula" that's guaranteed to work each and every time. If you're using a camera with a crop factor and a lens with a 70-degree angle of view (18mm on the digital 18- 55mm zoom), you'll want to first set the aperture to f/22 and then focus on something that's approximately five feet from the lens. And then, if you're in manual exposure mode, adjust your shutter speed until a correct exposure is indicated in the camera meter in your Viewfinder and shoot . If you' re in Aperture Priority mode, simply shoot, since the camera will set the shutter speed for you. Your resulting depth of field will be approximately from three feet to infinity If you're using 12-24mm digital wide-angle zoom and focal lengths between 12mm and 16mm. set the lens to f/22, focus on something three feet away and repeat the final step mentioned above Your resulting depth of field will be approximately two feet to infinity. (You must turn off auto focus by the way.)
That's a general rule which may not work all the time. First of all, at f/22 in a cropped sensor there will be lot of diffraction and the result will be soft picture.
To get the maximum dof one needs to understand the 'hyperfocal distance'. The same cambridge site has a very good article.

The Art of Image Critique - Taken from Nature Photography

If the moderator wish can make this a sticky in the critic thread.

Start off by taking some time to truly study the image and form an opinion of what appeals to you about the image, both technically and aesthically. Sometimes coming back to study the image again a short time later is helpful.

After forming an overall impression of the image, begin to identify the specific technical qualities of the image (lighting, color, contrast, composition, depth-of-field, background, etc.) that appeal or don't appeal to you. In just about any image, you can find both. Do the same with the aesthetic qualities of the image by describing any emotional response the image imparts. It's not uncommon to find images that are technically deficient, but yet impart a strong emotional response from the viewer, and visa versa. Feedback to the photographer on both the technical and aesthetic aspects of an image is useful.

Search for the words and phrases that most effectively convey your thoughts about these specific qualities.

Begin the written critique with what you like about the image. It is a mistaken belief that a photo critique should only point out what is wrong. In fact, as much can be gained by pointing out what it is that appeals to the viewer.

Out of the image qualities that you feel need improvement, pick those qualities that you can most effectively communicate why you think they need improvement, and how an improvement of those qualities would help improve the image.

Whenever possible, offer suggestions based on first-hand experience on how to improve those image qualities that you found lacking.

I have Nikon L24, Point & shoot Camera. Happy with picture quality.
(Though I have canon also Point & shoot Camera but not satisfied after I checked Nikon.)
I prefer & stick to Nikon for Still Photography. But often I miss the opportunity mostly as it takes at least 15-20 seconds to start shooting mode.
This is the 1st problem I am facing.:shock:
Second, Flash time takes more seconds to charge.:shock::shock:
Will Class 10 card of 32 GB will make my camera fast??:shock:

I want to install a camera on my bike also for video.
Is it possible to shoot 1 frame every second and make a video of that to show what is the way from Delhi to LEH or anywhere else?
Anyone can put some light on it?:confused:
