Hi..all, just want to share it to u all how to take this kind of pictures. Since I have so many compliment ( thank you very much) and some personal request how to take this kind of pictures.
So with hesitant, cuz I am just learned about photography recently....I will share some tricks and tips....
Keep in mind , this is not a lecture, since I am not yet a professional one.

First, from my view, u don't need to have a DSLR camera to be able to take this pictures. Some of myprevious pictures of flowers http://dwitrazaky.multiply.com/photos/album/23 , I took it just with a Point and Shoot camera ( Olympus widezoom something...) .As long as u know how to use it, thats fine. Just practice it first, till u could develop some skill how to get a good angle, how to maintain the focus, how to develop some sense pf colour etc...bla..bla..bla..
Beside most of PnS cmaera already equipped with some feature for Macro shoot, too. So just use it, and master it.
The result maybe as not as good like if u use the DSLR, though. With those blur effect, etc. But if u already master it, then later on u could move into DSLR camera then.

And for some of u who already have DSLR camera, I use Canon Digital Rebel XT with a special lense Tamron 75-300mm LD Tele Macro f/4.0-5.6. This is a very good lense that will enable u to take pictures, with those blur effect background. But make sure u got the focus right, otherwise it will be blur on the front but a crisp picture on the background . I think other lenses too u can use it, some Quantaray or Sigma, as long as they are Tele lenses with Macro ability. Not necessary 300 mm , though. Maybe some 200 mm can do it , too.

Some rules of thumb:
- If u could, take the pictures of the flowers either in the morning or in the afternoon, so the sunlight won't be too harsh or too bright. And it will give u those soft effect . It will be much better if u do it after a morning or the night before's shower's rain. It will give u those dreamy efect of water glistening on that petals. ( Next batch of picture, I ll show it to u this dreamy effect).

- It ll be better if u take a picture of flowers not the ones that grouped together, but a single ones. Make sure u have a contrast background, not the one with the same colour of the flowers. Usually I try to find a single flower with a green branches or a green bushes as a background.

- Try to take a different angles, not just the one with the same level of ur eyes. If u need too, just lay flat on ur stomach, or sit down or whatever position necessary. Try to take from under the petals, too. Don't be shy.

- Don't ever use flash. I hate flash. Instead use whatever natural light that available. I suggest if the sunlight is quite bright, just use ISO 200. Or if the sky kind of gloomy, use ISO 400 .Set the white balance into Auto White Balance.
For PnS, set into Macro setting.
For DSLR, set camera mode into P mode, if u r using Tamron lense like I did, put it into Autofocus, Macro setting. Then try to focus as good as possible. The first time it will be difficult, made me dizzy. Sometime u don't even sure whether its already focus or not. But just do it anyway. Make sure the focus is the nearest flower/s or the ones that the closest with ur camera.

- Take the pictures as much as possible. For my case, I always make sure every shoot that I take from the same angle or position, I will take at least 3 or 4. It will give some backup pictures as well. From my experiences, for the last several months before I mastered it, it always 20 : 5 or 6 . Or basically from 20 pictures that I took, only 5 or 6 came out good.

- Find a flowers with a striking combination of colours. Or just some with a bright colours.

- For me, I always finalize all my pictures with some touch of digital enhancement. Not too much, though, cuz u might lose the quality of the pictures. Also a good photographer won't use too much "some lied effect" unless u want to make it into different kind of artform ( not a real pictures anymore).
I use Picasa from Google, unles want to make it into watercolour painting, then I use Photoshop.
The features that I use usually : "I'm Feeling Lucky " or just " Auto Contrast" , then if u need u could use the "Sharpen Effect" and use a bit Tuning ( some highlight or shadow n color tmeperature).
Make sure u know that a good pictures always have POV/POI = Point of View. Just cropped the things that make ur pictures "unclean" or not part of the nice picture.

Well, I think thats all...Hopefully this will help u all.
BTW : the same friend challenges me to develop my Flowers's Pictures Collection into a calendar as well for next year. So , wish me luck then....
