I know the therory of photo stacking but when it comes to the practice im missing something:bonk: (brain cells more like ) briefly my set up is as follows. Camera mounted on a focus rack with the camera set to 1:1 on the forward end of the rack. Flower moved towards the lens so that the tip of the top of the flower is in focus. Now in therory if i take a series of photos moving the rack backwards i should get a set of photos each on of which having a part of the flower in sharp focus.
The result is i get the first photo is in focus the rest are blurred:bang:
Any advice would be more than welcome
 
With your setup, you need to move the rack forward to get the rest of the flower in focus.
 
Thanks guys, ive seen all the videos, and the rack is fully forward
 
I have never done any photo stacking so this may be total rubbish.

If you have the camera at the forward end of the rack and bring a flower towards the camera then the part of the flower closest to the camera will be in focus, as you have found.

As the camera is moved backwards on the rack it will, in each of the subsequent photos, focus on a point in front of the flower. This results in your first photo being sharp but all the rest out of focus.

The point Joe is making is that to focus further into the flower the camera has to be moved forward on the rack, rather than backwards.

Cheers for that Dave i looks like i shall have to keep trying.. the penny will eventualy drop... i hope lol
 
I'd of thought that if you set the camera 1/2 way up the rack, take the shot & then you get a picture thats clear at the front then DOF to the back of the shot.
Then you move the camera up a notch (1mm?) take your next shot, and carry on until you get the back of the shot clear & the front should the have DOF? then you merge all the shots together using whatever programme you've got
 
Start at with the front of the subject in focus then move the camera forwards, without changing focus on the camera and take the next shot. Repeat until you have a shot of the furthest point of the subject in focus then stack.
Think of it as slices thru the flower the first slice is the nearest point, and the last slice is the furthest point.

If you want to move the camera backwards, start with the furthest point in focus first.
