A great macro with a good level of detail and sharpness.
Great selective focusing and shallow depth-of-field.
Very good lighting as well.

The only niggles for me are the little bit of plant sticking in to the frame on the left and the darkness at the bottom which unbalances the composition.

I've done a mod to show how I would edit it.

All the best,

Joe

Hi Vicki, - Im copying my response to a macro shot question from another member to help with your question. The answer is in the details about aperture and depth of field.

Theres also a useful link that helps explain depth of field:
http://www.dofmaster.com/dofjs.html

Im also assuming your using a 105mm Macro lens?

Here my earlier response:

Its fun using a macro lens, but also challenging. as theres some learning involved.


Hers what to be mindful of in general with macros:

With flowers, since the lens is quite close to the flower, - the very tiniest movement of either the flower or the camera can cause loss of sharpness. The closer you get, the worse this effect will be.

Ensure that your camera is supported solidly, or the subject is completely static, - which might mean its better to bring a flower indoors, and place it on a bright (NOT SUNNY!) window ledge, and take shots there.

As a rule of thumb, you need to ensure your shutter speed is at least 1/(focal length * crop factor) if you are hand holding. In this case, it would be 1/(105 * 1.6), - Im guessing its a 1.6 crop factor here, I may be wrong, - but check your cameras manual, or on the net. So assuming 1.6, your slowest hand holding speed is 1/195th seconds. You will find that the closest faster shutter speed you camera can handle is 1/250th. And this is under ideal conditions, no wind, no flower movement, indoors.

To shoot slower, you need a tripod, or solid support, and no movement in the flower.

Aperture, - the bigger the number, - the greater the depth of field. So f/22 will make more of the flowers depth from close to the camera to further away, appear to be in focus and sharp. The smaller the number, the more shallow the depth of field, so for example at f/2.8 you may be able to have only a couple of stamens sharp with the rest blurred, - one of the reasons macro shooting is interesting.

Generally shoot in aperture priority mode, and choose the aperture you want according to the effect you want as above re depth of field; once you do this, half press the shutter, and check what shutter speed the camera has selected; use the guide above to decide if its too slow, and if its tripod mounted, it may not be an issue; if its too slow, and youre handholding, use your ISO setting t force the camera to choose a faster speed. For example, if the camera is selecting 1/100, with your aperture set, and you have ISO 100 selected, - then choose ISO 200 for the camera to use 1/200, etc.


Always use manual focus, so you can focus exactly where you want.
Focus very carefully where you want the sharp area to be. When shooting close, - the depth of field is so narrow, that the slightest change in your focus will make quite a difference.


Try this out, - practice, and you will be pleased with the results!

Hope you find this helpful,

Regards


Willie

One more comment Vicki, - this type of image makes a good basis for an abstract, - and as an example, Ive loaded a mod Ive had a little fun with.

Hi Willie,
wow thats amazing, it would make avery nice quilt design. Not even gonna ask how you did that....WAY to complicated for me.

I have printed your response so I can digest it. I will need to read and re-read before it goes in my head, but it sounds very good, many thanks for your time on this, its great to know there is someone who can explain things to me.
I will practice what you sugest.....watch this space. L O L

You may not be able to, but f9 is too big an aperture. Use smallest aperture (f22 or f32) whichever is on that lens. And a tripod, and no wind! Read about depth of field and depth of focus, if you haven't.

thanks for your help Gearoidmuar, I do have a tripod so I will have a go later with it.
Dof is a bit confusing at the moment but I will get there.
Need to ask the team another question.
