In Topic: adding a second strobe

Hmmm, yeah, my preference too would be to go for matched strobes.


Why go for an unmatched pair, rwe?

I was just trying to keep the bulk down a little; both for traveling and underwater.  I tried using a Nikonos 105 paired with the Z-240 some years back when I first switched to digital and decided that my diving enjoyment was significantly less carrying that much around underwater (in TTL the slower 105 also tended to overexpose pretty often).  But my present system is smaller so the difference between a Z-240 and S-2000 may not be that much.

As noted by others, I use Humann (book) and Fishbase (http://www.fishbase.org/search.php ) most often.  I also use Ross Robertson's Fishes: Greater Caribbean (http://biogeodb.stri.si.edu/caribbean/en/pages ) although it takes a little while to learn how to use it if you don't know scientific names.  But since he is using some of my pictures and has been very helpful in identifying species when I asked him questions, I took the time to get acquainted with it.  It does show multiple pictures of each species so you can see how much color variation there might be for a species and he is developing a module to try to identify a fish from a picture you input (but don't think it is active yet).  He also has a similar Pacific fish ID program but I have never used it since I have not yet dived there (http://biogeodb.stri.si.edu/sftep/en/pages ).  Occasionally, I also use: http://reefguide.org/ or http://species-ident...n.org/index.php but not often.

I've been with Alamy just over 5 years and have used both options and, frankly, have never been able to tell the difference in terms of volume of sales or income.


Maybe it's just my experience and the quality of my pics, but don't hold your breath on making fame and fortune from it. I've got almost 3500 images with them and have earned roughly the equivalent of a couple of lenses. There does't appear to be a big market on Alamy for u/w images. But, like i say, that might be just my images.....


Good luck with it!


Thanks for the info.  My initial four pictures just passed QC and are online.  Your camera/system and most of your pictures are much better than mine so I won't expect much, if anything.  I am mostly retired but doing independent consulting about 20% of my time.  Adding all those captions and keywords will give me something to do when I get bored but it would be nice to make a few $s so I could dive more often.

I am no expert but it looks like a Reef Croaker (Odontoscion dentex) to me.  It is in Humann (page 417, in my edition) and here:  http://biogeodb.stri...es/species/3796.  The black spot at the base of the pectoral fin, the non-forked tail, and possibly the laid down first dorsal are probably the keys to the ID.

In Topic: TTL Flash Control by Sony Rx100-III

I have a Sony NEX-5N and single Inon Z-240 strobe connected by fiber optics.  Most of the time I have the camera in manual and use the sTTL mode on the strobe.  For shots where the strobe is the main source of light I do not get a lot of over-exposures unless there is a lot of white in the picture.   I do get over-exposures frequently when shooting over white sand, etc. where the ambient light is high since I am slow at increasing the shutter speed to values where the strobe won't sink.  Previously, I used a Nikon 105 strobe with an adapter and electrical connection.  This gave me a lot of over-exposures because the Nikon 105 is quite slow at shutting off compared to the Z-240 so couldn't mimic the camera output very well.
