Macro on Monday - Guess What

It was a bit difficult to guess exactly what last week's mystery photo was though the clue 'bottoms up' was meant to indicate it was a drink. Anyway the virtual star goes to Adrian (who was exactly correct in saying it was a glass of white wine), Sue Garrett, Glo and Ragged Robin who mention it was a glass of liquid. Good try from Texwisgirl as a rain gauge could look like that:





It took me ages to find the photos I intended to choose from for this week's mystery photo. Found them in the end so here is a crop from one.
Guess What:


Clue: Can't catch this with a bent pin and worm.

Just for fun. No prizes. The correct answer and any guesses left in the comments will be revealed next Monday.


New Toy:

Ever since I tried Magic Lantern on the Canon 50D to get video capability I've hankered after a Canon which has it built in, along with sound which the 50D doesn't have. Then I read reviews of the new 70D and they were very enthusiastic so I have been waiting to see some reasonable prices for a body only version.

I ordered one yesterday from Amazon and it duly arrived this morning. Spent a while browsing the 100+ pages of the user manual while I waited for the battery to charge. Of course by then it had turned dull and started to rain but I did manage a quick trial of the video. The first part of the video is with the 100-400mm zoom lens at 400mm. The rest is the same but with an extra 3x digital zoom added in the camera. It did a lot better than I expected with the digital zoom and the poor lighting conditions:



The original .mov files totalled 760MB in the camera so I processed the video as an mp4 level 5 which brought things down to a manageable 77MB for uploading. No other tweaking was done.

Forsythia Stem Gall

Growing in the corner of next doors front garden is an old forsythia bush. It had got to the stage where some of it was almost blocking the grass verge which is the nearest we have to a public footpath so I asked permission to chop it back somewhat.

While I was disposing of the branches I noticed many of the smaller twigs were covered with nodules. A search found that these are Forsythia Stem Galls, probably caused by the bacterium Pseudomonas savastanoi.






It seems a long while since I tried a serious macro using stacked photos so I got out the Heath Robinson effort I built a few years ago. This consists of a stripped down PC DVD player and an Arduino Nano. The Arduino drives the small stepper motor in the DVD player which moves the item being photographed a tiny distance further away from the camera at each pulse. At the same time it tells the camera to take a photo once any vibration has settled down.

 

The Canon 350D was fitted with a 70-200mm zoom lens with a Raynox DCR-250 macro lens added. As well as natural light an LED ring flash was used on continuous light. Each photo has a very small depth of field:



72 photos were taken, each with the gall a tiny fraction further away from the lens so each had a different part in focus. Finally I used CombineZP which stacks together the in focus bits from each photo. The idea is to end up with one photo with all the subject in focus:

 

This is the best result I have ever had using CombineZP so am well chuffed, worth waiting over 20 minutes of processing time to get the finished photo.

Fungi Friday

Nothing new on the video front this Friday so here are some fungi seen on our perambulations this month:









All the above taken with an iPhone4
The last one taken with the Nikon Coolpix S9050



Have a great weekend observing the beauties of nature around you.

Red Sky at Night ....

... Midmarsh's delight.









Beautiful Autumn colours at tea time today. Taken with the Nikon Coolpix S9050. Cropped a bit otherwise exactly as taken by the camera.

On the Cut

On the Cut is a free app for videoing on the iPhone.
A quick test video:




It is so simple to use. Keep in contact with the screen to video, let go to pause, retouch to continue with the same video. Any time you are not touching the screen the video can be saved to the camera roll or deleted.

The video is a square format (480x480 pixels) mp4. Keep the camera upright, portrait orientation, or the video comes out sideways as I found out and had to get Youtube to rotate the above video.

Macro on Monday - Guess What

Another full house for last week's mystery photo. Congratulations and the virtual gold star to TexWisGirl, Adrian, Glo, Keith, Wilma and Sue Garrett for identifying the golf ball. The reference to eagle and albatross referred to terminology used for scoring in golf.


Bobby was very good at finding lost golf balls where people had been practicing on the cricket field.


   


Here we go then. A crop of an object for this week's mystery photo.
Guess What:


Clue: Bottoms up.

No prizes. Just for fun.
The answer, along with any guesses left in the comments, will be revealed next Monday.
