Default Rhodendendron, closer up

The weather has been a bit to wet to go out. So for the first time I played a bit around
with a pentax auto bellow M I got last year.

Because it was one of the things I bought before dropping down the stairs last year,
I already had a lot of fun dismantling it and straightening the screws that where bend.

All shots are with the K20d + bellows + pentax 50mm f1.7 except the starter that was
with the k10d and tamron18-200.

So a quick shot of the subject


Then going in a bit closser (4 focus blended images)


another angle (3 focus blended images)


and as close as possible (2 focus blended images)


The last one was with a flash and the bellows completely extended (15cm),
guess thats something around a 3:1 macro but if anybody knows how to calculate this please tell me.

Thanks for watching

Ronny

Really awesome pictures - that last one is REALLY close. I have no idea how to compute macro magnification ratios other than shooting a ruler and doing it mathematically.

Thanks again for posting about the dof extension ability - it got me to take a series on Friday. CS4 worked just fine with my subject, only it happened to be the ugliest worm or caterpillar or whatever I've ever seen. Next time I'll need to choose a better subject. CS4 does a nice job of aligning the pictures to the subject, making it possible to do stuff outdoors more than I had thought.

The reflection is very well done and how close can you get.

As Harriet says, awesome pictures! Thanks for posting, Ronny.
I'll have to learn this focus stacking technique, haven't used my bellows a lot at all.

Thanks Harriet,

the only problem I've experienced with cs4 is that it won't merge more than 4 full images, and have to scale them down (or crop them) before using them. Might be a windows-vista-photoshop-cs4 issue.

Hope to see some of your results soon,

Ronny

Thanks Rodney,

I think a little bit closer. The last shot was at 3.5:1 (as Harriet suggested shot a ruler and did the calculation), but if I add all extention tubes I've got lying around, I get a 4.5:1 magnification.
And to get really stupid for the fun of it added a raynox dcr250 on top of it and got a 6.3:1 magnification. (don't think that'll be usefull anytime )

Thanks Kjell,

I've had that bellow lying around now for half a year, bought it for 50€ in pristine condition (that was for about 5min I guess). Haven't used it at all, also didn't knew that you had to use shorter focal lengths for better results.
Now I think it's going to be another thing that I'm going to carry around with my macro stuff.

Hey Ronny,
the first thing that popped into my head was an expression that I haven't used in about 40 years...

...Whoa, far out man!
not sure where that came from.
