Firstly you need one of your camera attaches to this via the tripod mount. With this set on the tripod, your ready to go. Now this is the technique I have used, if it is wrong then someone correct me. Set the camera to manual mode, and manual focusing. Then focus on the nearest point to the camera...

It can also be done by taking multiple shots without a focus rail, but altering the focus slightly between each pictures. You can also use Helicon focus to combine the pictures: http://www.heliconsoft.com/heliconfocus.html

Saw the other one first, but my comments apply to this image as well! Lovely. Well taken. (Sorry, but don't like the border.Let the beauty of the flower & your excellent work work their own wonder!) Roger.

Thanks Snaphappy. I have the focusing rail but not the software to merge the pictures. Should be fun and if I can get anywhere near your results I shall be happy. Thanks for the time and explanation.

Hi Snappychappy. Great picture - if I get anywhere near I'll be delighted. I followed your ling to ebay and found two types of focusing rails - forward & backwards - another similar one that also moves side to side. Are there any advantages of the latter that you know of regards Bernard

Focus stacking
another similar one that also moves side to side. Those rails are done to help composing the pictures at large magnification ratio. When your subject is very close, trying to move the camera sideway just a "tad" is next to impossible on a tripod, so you use a rail that allows small, accurate moves...

Very impressive shot and a good subject for stacking.

Focus stacking
Firstly you need one of your camera... How good are those rails? I've been after a rail for a while. The Pentax ones are as rare as hen's teeth (I have only seen one on ebay in several years of looking). Are they rigid enough if you buy two to get both forward/back and sideways movement? Than...

Womble asked How good are those rails? I'm also interested but if they're cheap and nasty; poor quality and flimsy, I'd rather not buy one of these. Anyone have any comments on quality please Bernard

I have the Manfrotto 454 but it is single way. Not proved a real bother. Just need to get the tripod stable and in the right position. This can be a bother when shooting in the field but used in a studio or, as I do, my greenhouse to avoid movement of the subject then I am satisfied with my resu...

If one has the K-7/ K-5 one can do slight sideways and up/down adjustments using Composition Adjust - very useful feature, so for some shots only a 2-way focus rail is needed Andy

That's a ripper! If only I knew what 'focus stack' meant. Regards EDIT: just read the other thread, now I know what it means. I'll give it a try.

The Old way
slightly OT this, has anybody here, except Womble and myself tried older cameras? Oh yes - I have camera equipment going back to the 19th century, most of my favourite designs come from the 1950's though and my '59 Microflex has seen more use than any other camera so far this year. Can't get on w...

The Old way
slightly OT this, has anybody here, except Womble and myself tried older cameras? I know Kris has his Horseman and I play with a range of 120 and 127 format folders but has any one else tried similar 'alternatives' to the true way? Got a Bronica ETRSi, has its roots in the ETR of the 1970s so pro...

Birds and Depth of Field
Deliberately working at F4 (a) to make the most of the light and (b) to try to get some nice shots of a Motmot, when the second of the pair appeared briefly. So I've got one in focus and then the other and no time to change aperture, cos they don't hang around for long - in fact it was the only occa...

#1 is a nice shot. I guess you weren't too far way because at 20m / f4 / 300mm you'd have had 70cm DoF and both in focus however if you were at say 10m / f4 / 300mm then that DoF has shrunk to just 17cm. f8 would have doubled those DoF distances. If I know what I'm shooting I just make a few...
