downloaded some plans today to finally attempt a go at making a tent to take some pics..quickly learned that tents and lights are just one piece of the puzzle when it comes to taking pics like I am used to seeing here...camera is HP Photosmart 935, no macro settings that I could find, did what I could. Critiques and pointers gladly accepted, thanks for looking.

I tell ya Ron those are some pretty good pictures. I think you did a great job. I need to do something about a photo tent but working full time, part time clock shop and trying to turn there is no time.

Pictures look good, Ron. Might want to try smaller lens opening and longer exposure to get a little more depth of field. Can use a tripod and the camera's self timer to eliminate camera shake for long exposure times.

any idea how to look for smaller openings and exposure times in wee little words for the photo challenged? (I knew I shoulda stayed with reading comic books)

Thanks Bernie for the kind words, the tent took me about 20 minutes and twenty bucks (already had the 6500K lights over the lathe) got the info here

Thanks for the link Ron. I'll have to go to the store later and get some materials to build one. :)

Ron,
Will just repeat the advice I received. Read the owners' manual. Lacking a "photographic" memory, I refer to mine fairly often.

Richard,

I found very little info that I could use in there, but a fellow turner not too far from me downloaded the manual from the company site and he was able to give me some pointers as to what I was probably doing wrong. Will try toredo some pics today/tonite if I find the time, this intrigues me and I really want to get a handle on this part of the woodturning culture (Heck, maybe I can doctor up the pics and make the turnings look better):D

Ron,
For "doctoring" the pics I just use a combination of the software that came with Vista and the program that came with the camera. Together they do most of what I want. Have looked at a couple of the freebee online programs that are said to be good, but seem to be unable to use them without an owners' manual.

Use of Aperture/F-Stop

The aperture is one of the more confusing parts of how cameras work. The aperture setting is also sometimes referred to as an f-stop. While the shutter speed affects the duration of light hitting the sensor, the aperture affects the amount of light hitting the sensor. To put it simply, the aperture is the part of a lens that dictates how much light is let through to the sensor – if it’s wide open, lots of light gets through. If it’s closed down, not much light gets through. In essense, it performs the same as the pupil of an eye. If you are in a dark room, the pupil is open; sunlight, the pupil is small.


Aperture settings are expressed as decimal numbers, and work opposite to the way you’d think – a higher number lets in less light than a lower number. Each aperture has an Open, and a Closed – the most and least light it will let in. In between it is what is known as the f-stops, or aperture settings – numbers like f1.6, f2.2, f8.0, f16.0, with many in between. Different lenses can http://www.homephotog.com/tutorials/images/f-stop.gif
have different apertures – for example, a cheaper lens may only open to f4.0, not letting in as much light as a more expensive lens that will open to f1.6.

Changes to aperture will effect "Field of Depth (http://www.homephotog.com/tutorials/depth.shtml)" as well and you should refer to this tutorial as well.

Finally, another good utilization for apature is when taking night time city scenes. Utilizing a smaller apature setting can help enhance the "star like - radiating" effect of lights, which can lead to some nice nightscape images.
