homestar, The HDR version is looking a bit 'scary'. Just noticed you are using Gimp 2,6.7. I'm not familiar with Gimp; but found a tutorial at the link below that you might find useful when considering ' global ' adjustments. (adjustments that impact entire image) Working with masks and selections f...

Welcome Ralph,

It's unusual, on this forum, for a new member to go unnoticed, so thought I would jump in with a welcome. (5 weeks late).

I had a look at your website. Interesting viewing

Looking forward to seeing more of your macro.

Something like - camera sensor size - bellows extension (if any) - lens focal length - lens aperture There is a table, titled 'Close-Up Depth of Field for 35mm Cameras' on page 27 of "The Manual of C...

Interesting (intéressant)

Nice :wink: I like your customised dial Charlie 8) very nice! Any tips in regard to attaching the AS clamp and AS dovetail to the Velmex? Was the RRS clamp good to go as/is, or did you need to adapt it to line up with the holes on the Velmex? As David mentioned, finding a suitable AS clamp is tricky...

Sam, Here is a quote from a novel I have been reading during the last couple of days (haven't been able to put it down). It is an excellent novel by Barbara Kingsolver called 'Prodigal Summer'. Local library should have it. Thought it might be of interest. Seemed relevant to your question, so though...

Strobella, Small Umbrella Flash Diffuser

For the fun of it I'm going to get hold of a 20X microscope objective to see how it does at this power.

Look forward to seeing those results

Hack, Welcome to the forum :) Interesting model. Do you have a version of the image without the vignetting and other effects applied? I read an interesting article the other day that initially used a small model car as an example in an 'Apparent Light Size' exercise. http://strobist.blogspot.com/200...

I remember seeing about some work a guy did on that, with a particularly dirty fly, some carefully controlled lighting

Could you be referring to Ted Clarke's:

"Constructing a Scanning Light Photomacrography System" ?

Linden, thanks for uploading the images of the StackShot, automated macro rail. Linden wrote: The rail is 1.1kg As a comparison regard weight. The Novoflex Castel L (for example) weighs 450g, so this rail at 1.1kg is managable, especially when considering its capabilities :) Linden wrote: This is a ...

Thanks for the comments. :) Sole, The diffuser used at the time was partially blocked by foilage; this was unintentional; but also unavoidable. Just a basic diffuser made of foamcore board with a 3-ply tissue paper diffuser attached via an elastic band. The flash is attached to the camera via a brac...

Looks like we need a couple of images of this gizmo in this thread . Can you arrange that Linden? The base plate/rail of the unit. Is that an Arca-Swiss dovetail? The standard camera mount in the image looks like it would be responsible for considerable load especially in the field or in a vertical ...
