Experimenting

As the title says i have been experimenting, I wanted to know what the difference Is when i used 3 images taken at +0.00, -0.70, and +0.07 (camera settings) and then using just one of the images loading it 3 times into the software and manually putting in the values 0.00,+2.00, and -2.00 I did expect a different outcome, What do you think ?

I took inside shots as i also wanted to make sure that a problem i was having was due to poor light ( getting banding down one edge ) That seems ok

and as a added bonus i have just noticed buds on the poor cactus

1. original image 0.00
2. using the three images
3. using just one image

Re: Experimenting

Thanks Patricia,
It is a experiment that i will retry when i get (hopefully for xmas) the full software, And i quite like the third one better (with one image) but that could be down to different monitors

Re: Experimenting

Hi Palms,

If U check the histogram of the hdr U can deal on witch is the best way, I agree with Pat the second one is nicely saturated I like this good composition. If U set EV at the camera that is not the same than set it by the software(IMHO). I've tried with a raw, I've had a shot (call it: opt). I made the opt -2EV by the camera as well and have checked to set the opt to -2EV at raw converter there was difference between them.

Re: Experimenting

Palms - count me in for liking #2 better as well. Nicely saturated colors and a broader range. Nice image as a whole.

Re: Experimenting

Palms, the shadows to the left of the oranges (tangerines?) are more pronounced and the wood in the knife holder is more saturated in the 3-image photo. Nice to see some of the variations possible.

Re: Experimenting

Thanks for all your input, What surprised me was that there was not as huge a difference between the two as what i expected ( i expected the one made with one image and inputting the brackets would be more like the original ) Mind you when time allows i have some more experimenting to do
C.J. they were Clementine's and with a bit more thought i should of turned the one on the right around and wiped the bit of soil off the pot
