Mammillaria supertexta

The newest revision of Helicon seems to have markedly improved haloing and also mush when processed in the mode B. The image of the full plant did not require retouching. In the spine close up, the program had a more difficult time. the spine detail was taken with a 25mm. luminar on a bellow draw of...

Lovely image Rik. The edit definitely improved the image. Ice is sure pretty..and deadly. Take care and keep warm.

Thank you Doug. It's been a joy to watch this plant develop. Last year was the first year the pups flowered. You'd think it would be distinctive enough to be easily identified. The contrast between the white fur and the rich hot pink just glows.

Doug, having taken high magnification images of opuntia glochids, I second everything Dave said. The glochid have loosely attached spines that are barbed and have a breakaway design. Once the barb has set, it is nearly impossible to extract the full spine. I have used tapes, coated my fingers with E...

Unknown mammillaria

Ten or so years ago, i got an offset from a club member, a spiny ball 3/4ths of an inch in diameter. It's now about 9 inches tall, has 7 offset heads that sprout mid stem, and remains nameless. The annual grown ring is clearly defined. Both shot were taken hand held with my G9. On the flower close u...

Before I had a dedicated macro lens, I used a Sigma 75-300mm which gave me a magnification of 1:2 at its macro settings With a Canon 500D diopter, I got some very passable results. As Dave said, macro lenses are meant for close focusing and higher magnification. They are well corrected prime lenses ...

Ken, Joan, and Dave, thank you for viewing and commenting. I have in the past eaten the fruits of some mammillarias. In Mexico they eat the fruits of opuntia, known as tunas. Several other cactus berries are also eaten but I am not sure which. But Dave raises a good point. Systemic poisons make nibb...

Mammillaria nivosa

My Mammillaria nivosa has always looked nice, but it never really grew much. This last year, it put out a number of offsets. It is telling me it wants an upgrade from its three inch pot. I love the ripe red berries which I will soon open to see if I seeds set. Hope you enjoy. Irwin http://www.photom...

Love shot #1. Being at eye level with the beetle makes the shot more exciting. Looks like a tank. Great shot Joan.

Great stack Brian. I am amazed to see a 5 slice stack hand held at that magnification. Great work.

You are getting some great images from that G9 it seems there Irwin. Never seen one of these before as I can recall. :D Ken, thank you for your kind comments. I approach shooting very differently and can get shots otherwise unavailable by using the G9. I also experiment more. Are you doing black an...
