Doing the experiment with filters and fixing aperture and time was not a good choice, despite the fact that I got some nice images with differences in exposures and lighting. The main problem is that, I never though of the consequences of the EXIF data that would be attached to the images, and which are used primaily as a source to calculate the exposures relations. Hence, both softwares, Photoshop and Photomatix, had a problem with setting the exposure values to the images even though the images are clearly different in the light level.
In photoshop it was even harder to set up the values manually (even though it gives you the option to do so), but Photomatix, was a bit more flexible in changing the values.
The other problem was that changing the filters is not a practical mean at all, specially when the lens are on manual mode (auto-focus mode is hard to work with in such darkness if not impossible at all!). When moving the filter in and out of the filter holder, there is a great chance to change the focus of the lens a bit after fixing it (and for someone clumsy as me, it was one hell of thing to fix the camera in the first place!).
There were two methods of shooting that I followed, and hence I made 2 series of shots related to each other (but when combining I felt somehow free to combine some elements from this series with others from the other series). The methods were like (of course with a flash pointing somewhere):
- Stacking the filters altogether and start the shoot. Then, remove one filter and shoot again, and doing so until all filters are removed.
- Shooting each filter alone without stacking them altogether.
122. and Alexander was back again to normal
123. the prisoners of Zimúrá were taken away
124. to stand in before Alexander, the hero
125. and there they told him their secrets
126. their tongue and their strings of writing
127. and how are they born and buried
128. some of them are burned when they die
129. and some others are buried in trees trunks
130. and Alexander commanded the wisemen
131. to record everything they see and learn
132. and when all documents were recorded
133. he ordered the beasts to be cleared out
134. and their bodies shall be hung on the trees
135. for they are children of sinners and beasts
136. and no use of them in this life and this world
137. and thus Alexander wanted to make them a lesson
138. for the other beasts and cruel hearts in the place
139. and then he ordered what had remained of his men
140. to dig up graves for what is left over of the bodies
141. and the mourning for three days started
142. and he cried with a saddened heart
143. for the lost of his beloved, and the lost of loyalty
144. while injuries were handled and supplies were taken
