Tyler, keep an eye out for something like an EL Nikkor 50 mm f/2.8. They work really well reversed on bellows -- sharp, easy to illuminate around, easy to set. Do they make a canon mount and will I be able to stop it down? I need to throw my 50mm on my bellows reversed, I am not 100% sure I have tr...

And let me just add that dpi is an outdated term although I use it too sometimes because old versions of photoshop used it to mean pixels per inch. Strictly speaking dpi means dots per inch and printers use more than one color dot per pixel. But in photoshop, those both refer to print size, which i...

Ouch

Dug this "bee" out of my daughter's pool. Do you think that is a stinger? I am really not sure. Whatever it is, the stinger measured about 4mm while the entire insect itself measured just over 11mm long. Weird end to it I thought, not very sharp, spoon like almost. I tried a more straight on approac...

It is far more reliable to just be aware that your images are likely to be sharpest at some intermediate aperture, probably not wide open and certainly not full closed. Run some experiments to determine where that sharpest aperture is, and use it. This sounds WAY easier - maybe more time consuming....

That's a nice technique that I will have to try. It works pretty well - and they come in a few different colors. This one happened to have a blue tint to it. You have to put your camera at the right angle to get the reflection you want. This is one of the very few where I got low enough to get a fa...

You know my main motivation is to make sure i am posting right in these forums. My secondary motivation is to know as much as I can. I think I read somewgere in the hyperlink that some people do not understand magnification as well as they should (or something to that affect.) I am not sure if I fit...

I'm a PE teacher by day...haha just kidding- well I really am but that was a bad joke. Do you feel like your explaining this to a kid - because I am having some serious high school flash backs right now. I used a CD-RW for the back ground. In the first image I couldn't diffuse my light from directly...

If you know the size of the subject then just count the number of pixels it consumes in the image and compare it to your sensor size which is 5616 x 3744pixels and 36 x 24 mm. This image should be pretty straight forward for calculating the magnification. Hmmm.....so the subject is 4 mm and fills 2...

Hippodamia Convergens

We just call them lady bugs - but I think this is technically an Asian Lady Beetle. My understanding, and please correct me if I am wrong, is that these were brought to California to eat some kind of tree mite/pest. Now they are harvested in the Northwest, sold out of Canada into the US as a method ...

Interestingly - it is the 64 bit version - I just double checked.....when I changed the memory allocation to 3000 it said something liek 1835.

We will see how it runs. Thanks.

Thanks Rik - I will give that a try. I am actually running 64 bit windows 7 on that particular system - and running the 64 bit version of ZS (or so I think.) I will try what you are talking about. Any idea as to why the program worked with one stack but not the other?

I hope this is helpful. Thanks for reporting the bug It was helpful thanks. If it helps you at all- the retouching tool was running rough and slow right before the crash. I tried again a second time.. I was using the "S" key to view the source and the following message popped up. http://www.photoma...
