Thanks for the warning, :) but I was going forward in any case , .. Man did I screw it up on Saturday! Worst day EVER! I heavily under exposed. For Sunday I scaled back dropped one stop exposure compensation across the board , andd shot as normal , I was very happy with that so maybe next weekend Ill drop another,, but going straight to base iso was just to drastic a change and I had no idea what doing. Ill put up some pix for the week later.

This was early and a bit under exposed at base ISO, I want it darkish since its early and the warm tones are nice. View attachment 216498

This spoonbill is after strong under exposure and pushing in post , I dont like it.

This is what it started out as,

This caspian tern is a bit better , still at base ISO and after pushing in post

Later in the day I came across some Eastern Kingbirds , this One is at base ISO and pushed

This shot I took at ISO400 when I decided I wasnt going to trust base ISO entirely , I think its one of the best results of the day. Which had sort of a bright hazy difficult light.

Sunday, I just set the compensation down one stop , this is also in the morning also somewhat hazy , its at ISO 400 minus one compensation.

This is later on sunday with one of the few moments of clean light ,I was able to get the shutter speed up to 32000th of a sec with the -1 comp at ISO 800View attachment 216505

Im not thinking that my demonstration is very instructive, other than to say its possible to drop the ISO to base and push , or one can drop the ISO a bit and underexpose and push a little in post , with really fairly similar results after everything. The biggest determinant of the image quality was probably the distance to the target THEN secondly would be saturating the sensor to midpoint. IF I was going to come to a temporary theory , I'd say that some low ISO , maybe 200 or 400, is better than either base iso OR 800. I already read that after 800 the conversion is not as smooth from signal to image because its done digital rather than analog and so above 800 there is zero reason to raise ISO.
It was certainly easier to process the image with some ISO to begin with , and doing a lot of pushing I tended to get either a dim sky or a spotty grainy look to the sky , but certainly that may be my ineptitude rather than physics.

I did have a quick look at it but could not see the benefit,i dont see anything in the results J-see gets that he didnt get with the 750 and 300mm pf f4 using iso,certainly not in web posting,look at the results Pete (Blacktop) gets using iso,run through flickr and the great images are made using iso.
The other important thing to me with bird photography is to be able to check the image immediately after taking,i want to know what i have chimping or not,i do also believe the Nikon engineers and software producers know more about sensors than i ever will.

I also tried the Jsee trick, my results didn't inspire me to continue with it, maybe I was missing something.
Though with my macro insect shots, I use the settings iso200, 1/200th, f16 with the pop-up flash for everything. When there is some ambient light, the exposure is pretty good, but when shooting into deep shady spots, the shots are a stop or two underexposed , I find it is better to do this and push back up in PP than to raise the iso, which produces noisier images.

They, canon nikon pentax? etc surely know more than me too, ,, but the thing is they ,, understandably , dont want to anything that will cost them profit.,or might alienate old customers. My interests as a consumer, are not precisely in line with their goals as a producer. I think they have a vested interest in making sure one is never quite satisfied with the current products. For instance Theres zero real reasons why they cant present the full gamut of RAW data on a histogram, There's no reason why one couldnt get a brightened jpeg preview of the photo as its shot at base ISO so you could see what youre doing., and theres no reason to provide ISO 1Million.
I see lots of great photos using ISO , including Blacktops Flickr. But Im still attempting to push what the camera will get me.

Whatever gets you the shots you do , obviously is working for you. Personally , I think the ISO issue can work either way , that its not important to raise ISO , or that its equally unimportant if you actually do raise the ISO in the lower range. Obviously BIFs are uncommon at your macro settings but the ISO 200 is probably still a good bet for that too. ( I'd also say the same that pushing the underexposure even two full stops seems to work fine , three though , and I think you start getting some distortions in the way the data is presented making colors weird )

the Spoonbill is on my list for this year, they come to a lake about 100 miles from me in the winter, going to try and get some shots then.

What is the place you frequent the most ? I forgot. I googled so cal down by the gulf and just dont , to my surprise, see many parks in green.

San Jacinto wildlife area and Lake Skinner are my 2 most frequent places, both less than 20 miles from my home (Menifee), if I go to Lake Hemet or Yorba Regional park they are probably a hour away.

I google mapped to see what these places look like .. I couldnt really get an idea of what theyre like on the ground , it looks like your big wild areas like cleveland are really rugged , maybe to the extent that you cant really get in there? Ours tend to be low and wet marshy areas... so you just dont Want to get in there. :) Lake helmet looks adjacent to some nice wild areas Yorba looked like an apartment complex though.

At the moment San J is all dried up, they only keep the front pond filled, not to green anywhere, sourthern cali in summer is like a huge ant hill.
