#332606 Nikon AF Micro-Nikkor 200mm f/4 D IF-ED Lens

Maybe you can try 105VR+1.7x TC for a similar lens length but with a higher ratio result and a more versatile combo for trips...

#321731 What Strobe for D7000 ? (Hugyfot housing)

Posted by davichin on 30 November 2012 - 05:29 AM

I have the same camera and housing (D7000 and hugyfot) and a lot (too many...) of strobes. First advice is to strongly reconsider optical connection because it is more reliable and a lot cheaper (you can save around 100€ or more to your budget if you go optical).
I have subtronics, seacams, sea&sea 250 pros and YS d1s and, for your budget, I would choose either second hand YS 250 pros (there are people selling them because of weight at around 1000 - 1200 € for two) because they are very good for WA (but don´t have S-TTL ), or new D1s which you can buy two within your budget and are lighter, have S-TTL for macro and, although not as powerful, they can do the work for most of the WA situations... Inon Z240s are also a safe bet.

Wet heat is faster and more convenient... you can boil a couple eggs&sausages at the same time!Posted Image


#319343 Diving Oceans On Other Worlds

I don't know if many of you have seen the fossilised crinoid photos disclosed by Richard Hoagland. Very interesting. A collector of marine fossils for 34 years identified it as an early crinoid.


Now, what we really want to know is if there is an unidentified commensal shrimp living on that crinoid or if it is just a typical Periclimenes amboinensis one!!! Posted Image


#318188 Flying Octopuses - comments on the proliferation of these images

Posted by davichin on 11 October 2012 - 05:44 AM

Where is the line?


I know where MY line is, and touching a subject (throwing an octopus in the water column in this case) is well well beyond that line.

The best that can happen to those "other worlds" is not being discovered by humans...


#316168 Wetpixel D800 review

Posted by davichin on 11 September 2012 - 01:13 PM

I've used both D7000 and D800 for supermacro side by side and it is much more difficult with the D800. I think in the above example, DOF is the same but FOV will be different. Holding FOV constant, the DOF will much much narrower on the D800. The more I read about the issue more confused I get by the physics behind it, but in practice I don't think there is much question.


FOV is where the trick is: we can fill the whole image in a 7D with a 23mm shrimp at 1:1, but that shrimp in FF camera at 1:1 will have a lot of surrounding area. In order to get the same image of the SAME subject we have to go 1.5:1 and that will reduce the depth of field...


#313185 Photo contest question

Posted by davichin on 20 July 2012 - 08:05 AM

About manipulation: The contests rule almost always state what you can and cannot do. There are even some contests with different categories for manipulated (unrestricted) or unmanipulated (restricted) photos like OWU.
You can enter the same picture in as many contest as you want as long as, at the time of entering, it has not earn any prize. Once the picture has won anything important, you will have to read the next contest rules to see if they allow prized pics or not.

About rights: read the rules. I do not enter any contest where the rights go beyond "only using the winning pics to promote the contest etc..." some contest even keep the rights of all the entered pics (whether they win or not!!!)


#308028 Viewfinders: 45 or straight?

Posted by davichin on 05 May 2012 - 09:08 AM

I have both (Inons) and, if you dive a lot, get the 45 because you will get used to it and framing will become second nature. If you dont dive regularly get the 180 because it will be a great improvement from the start.


#97351 Tipping is in the culture

Posted by davichin on 02 August 2006 - 01:23 AM

Having lived in the U.S. for two years and, coming from Spain, is strange that a 15% tip is mandatory and people always used to say "the waiters have a very low salary....they live only on the tips.....etc...." while in Spain is more like what Stu talks about the Philippines, a small amount (no %) or even nothing and you will not get grieve from the waiter or whatever. Here, extra tips are for extra service (service/attention/work beyond what is included in the originally paid service).
Whenever we travel we ask the travel agent how is the country we are going to in this matter. Some operators (like Aggressor) include some info in their website...
