All of these were shot with a 30 second exposure and lit with a cheap penlight from Radio Shack....I used it to 'paint' the light onto the objects by hand.


The only difference between the three shots in this tryptic is the way I painted the light onto them...the background and position remained the same.

the lighting and feel seems very nice with all of them, but i wish there was a bit more sharpness (not sure if this is limited by your technique). creative technique - good results too

The technique does enhance the slightest camera vibration...I need to use a sturdier tripod next time because I'm walking around it the whole time....but I could probably sharpen them a bit in PS...I'm still learning the more subtle finishing techniques.

Here are the settings that I use most frequently for Unsharp Mask:
10%, radius 40, threshhold 0
100%, radius .5, threshhold 0

they have obviously different effects, and seem to cover most bases where sharpening is necessary for me. I hope you find this information useful, or at least that I'm not telling you something you already know.

I think the white tracing around the border is like 2 pixels too thick.

Just in response to Damon,

Good unsharp mask settings will vary depending on the pixel height and width of the image you're working on.

For example, if you're working on a 640x640 image then a radius of 5 pixels would be comparatively large and noticable. But if you're working on an image more like 6400x6400 then a 5 pixel radius would give a much more subtle effect.

I read somewhere that a good starting point for radius is the smallest dimension of your image divided by 100. So for a 640x480 image a good place to start would be .48 pixels radius. Vary up and down from there depending on how strong you want the sharpening to be.

Gentle nudge. :)

I love this technique, especially when the subject is the older equipment. It gives the image a nice warm antique feel.

Gorgeous! I love the mics! Is that a Neumann?

Re: the slight unsharpness, that is an artifact of the moving light, which blurs the shadows we normnally expect. Our visual perception of "sharpness" is controlled by the crispness of definition in the shadows.

Nice shots!

It's an old Shure Bros. 55S. Found it in the attic of an old church.
