Viola in the stars

rhermans

A while back I was trying to get some close ups from a viola in the garden, using 3 off camera flashes, and I don't know how close I was, guess a bit closer than 1:1.

The surprise whas the milky way that appeared when looking at the shots on my pc.

It's partly pollen, and they where cutting a lot of stones close by with a lot of fine dust.



It's a focus stack of 3 shots

Kiron 105mm + Tamron tc1.4 – f/11.0- 1/125sec -Iso 140

Cool shot.....You say you don't knopw how close you were. but.......do know the lens used?
Extension tubes used or what else beside the lens was used.......that would give a lot of folks
an idea of the actual magnification and distance.....

thanx for sharing.

Ronny,

Last winter I did some indoor stacked shots of African violets and saw the same thing I think you are suggesting:

I assume you mean the white spots. What I found is that stacking with the PMax method in Zerene created this effect with certain flowers. I think what it is doing is exaggerating variations in luminance, but I am not sure. After experimenting, I found that I could greatly reduce this by using the DMap method and setting the radius sliders (both of them) to a double the default value. I asked the software's author, and he said that I had stumbled on what he recommends for images without a great deal of detail.

The originals had the same white spots, some of them when zoomed in look like pollen, the others are just to small to say what they where.

I stacked this shot in photoshop cs4 where I haven't seen the effect you describe here.

Thanks for helping

Been checking if I wrote it down somewhere, and was lucky
Kiron 105mm + Tamron tc1.4 – f/11.0- 1/125sec -Iso 140
so that would give a 1.4:1 magnicification.

Thanks Scott
