Hello Amr

1/60s shutter speed is too slow for a macro picture, thats why the picture is blurry.

You're moving, the Nudis moving, so start at least at 1/250.
You have to compromise with f stop because you may want adequate DOF,
which means f16 or higher. (But sometimes you may also want to keep the background blurred!)
So when you have a great slow/stationary subject like this, multiple shots are in order, trying several combinations.
Congratulations on getting nice and close, filling the frame with your macro subject. One other tip, when possible, try to compose with the subject moving towards you.

Sorry to disagree with Willie but it seems to me that the blurriness isn't from motion but rather from not being able to focus well this close. If the flash fired and synced well and the ambient light wasn't too bright the nudi should be sharp since the flash duration is so short.
So, did the flash fire, and how bright was the ambient light. F8 might be a bit too open but with this camera it should be OK.

Almost all, if not all, of my nudibranch pictures taken with my Point-and-Shoot were taken at 1/60.

There is a "focus window" that pops up when in macro mode, that allows me to focus on the part of the subject I want, usually the rhinophores. I also take several shots of each subject to (hopefully) ensure that I get at least one shot that is in sharp focus. However, surge, current, and breathing do make a difference in being able to keep the subject in focus.

Keep it up, and above all, have fun!

Just for everyone's info, F8 is the smallest the G11 can go!

Also shooting with the G11 myself, I would think more that the image is not entirely in focus. Ensure that the focus box turns green at the spot on the subject you want before you press the shutter. You can reduce the focusing box to a smaller box for more spot focus.

It looks to me like the camera has not focused correctly, maybe it was too close.

FYI, To get TTL with the internal flash on a canon compact, you must use Av mode, which only gives you 1/60th of a second shutter speed.

In really bright light 1/60th is not ideal, since the "ambient light" part of the shot might be blurred, but in many cases (a subject not brightly lit) for macro the speed of the flash should eliminate any camera shake blur.

so imho everyone is a little bit right :)

i already using the Av mode :) but this nudibranch were placed on 20ft and there was a big surge

i have a question what is the better when the MACRO mode is on to be very near from the subject or a lit bit far and i use the zoom ?
