@tenida...you should have taken the complete palm tree...or only sky...

Sky is beautiful

sujoy: wrong way to do the tests.

1. Make sure the scale you are shooting is straight vertical or horizontal. You could hang flat to a wall, or lie it flat on a table.
2. Now shoot making sure the focal plane is parallel to the scale.
3. Shoot on mm/cm side. not inch side it will be easy to calculate.

this will show us how much is the magnification.

check this

Magnification tests ( Added the images.)

@toofan, sujoy: Why don't you try something with smoke? It would be interesting to see the results.

 

[sujoyp]

@astroutkarsh...2 of them are great...that full leaf and that pic with violet color..

others r nice attempts...to tell the truth I am not able to take droplets as good as these

Sujoy: this is not cm these are mm. Mili meter.

thanks for the pain you took.

It means you can go 1:1 with 55mm Macro + 68mm extension.

Your 1st shot is showing the reading of 48mm. this means this lens is 1:2 macro not 1:1.
you could get more magnification with a 50mm lens + 68mm extension.

 

[sujoyp]

@toofan yes I already know this....its a 1:2 macro lens...the AF and AFS version of 55mm 2.8 is 1:1

yup its mm sorry messed it

Now with this macro I can take flowers , bigger insects and any thing that a 50mm lens can take...its very sharp

now some smoking shots...my 1str try...now I know it need daylight...will give a better try next time...

[Zangetsu]

nice smokes..how it is blue??

 

[toofan]

sujoy: you need to fire the flash at the smoke and then add coloured gradiend. then see the wonder it does.

 

[sujoyp]

@Zangetsu its originally blue...its from agarbatti stick...

@toofan...but if I fire flash...I cant see any smoke I tried it at 1/200 shutter speed with ISO 200

still I will try different setups for smoke to see if anything amazing comes up

but as i said Blue came automatically I didnt add any color

 

[toofan]

add light from back/side of smoke.

 

[sujoyp]

add light from back/side of smoke.

but back should be kept dark else how I will get the smoke reflection at all...i set it up in a way that sun light comes on side of the smoke...

toofan give me 1-2 day and I will find a solution to it

 

[toofan]

Ok I too will try this today let see what I achieve.
