Up Close And Personal

This week, make use of the macro feature of your device or camera, and snap a photo of something really up close.

Contest Rules:

1. Any digital photo or digitally-scanned photo relevant to the theme will be accepted within the contest period. In case there's a gray area, or you're not sure if the picture is suitable, check with me first.

2. Please resize your digital photo to no more than 800 x 600 or 600 x 800 pixels. You may also crop your picture if you wish. You are also allowed to adjust the brightness and contrast of your picture but these should not dramatically alter the look of the picture. But other than those, any form of picture editing or modification is not allowed. This is a photo contest, not a picture editing/special effect contest. You may add a watermark or your name/nickname to the photo for identification purposes.

3. Upload your photos to any of the photo servers such as imageshack or photobucket. Then post it the relevant contest thread and link your picture using the img command. PM me if you do not know how. Alternatively, you may simply upload your image file to PF, and then have the full image displayed in your post.

4. Only ONE picture per member per contest. Once a picture is posted, it cannot be changed other than a total withdrawl by that member from that week's photo contest. Exceptions will be made for modification to comply with the rules, such as resizing.

5. At the end of the contest period, I will open a poll and every PF member can vote for the picture they like best.

6. Note that in case we have a large number of entries, I will do the polling in more than one thread. If that's the case, you can vote in each of the polling threads. The photos will be assigned in the polling threads in the order they were submitted.

7. The photo of the subject must be something that you took directly, not via in intermediary medium, and not taken by someone else. Unless otherwise noted, a photo of another photo, painting, print, etc. does not qualify.

8. You can use a picture only once. Once it is used in a contest, it cannot be reused in another contest.

9. Please post only pictures meant for submission in this thread. Photos not meant for submission must not be posted in the contest thread. Posting of more than one photos by a member may result in an automatic disqualification from the week's contest.

Zz.

End grain of kempas wood (Koompassia malaccensis). I've done about 4,000 of these wood end grain shots for my wood identification website but this has always been my favorite because of the way the grain spikes cause the lozenge-shaped aliform parenchyma to swirl.

Reminds me of a printed circuit board, on LSD!

And on that note, here's a picture of the first and last printed circuit board I ever made, from scratch:

I'm curious how long it will take before someone identifies this object: time starts now!

Two Danio kyathit (striped version), male in front, female in back. They are about 2 inches long (~5 cm).
They are relatives of zebrafish (Danio rerio) that I used to grow to sell to labs for research purposes.
The single dark dots on the lower face are large single pigment cells.
