another comparison shot.. twilight portrait has much less of an effect in DM 3.8... the low light picture is a lot darker than in 3.5
DM3.5 twilight portrait
Exposure Time 1/4 sec
ISO - 200
DM 3.8 (beta) twilight portrait
Exposure Time 1/6 sec
ISO - 200

Can someone give good how-to tips on:
- Spot Metering
- Normal Metering
Like when should we use which and under what condition? I remember previously there was a few posts on this, maybe can someone help to share some tips? 
I'm gonna say what I know from my experiences with them:
Normal metering measures the whole scene and sets the shutter speed and ISO accordingly. If there are highly bright areas and highly dark areas at the same picture, using normal metering may, for instance, priorize only the highlights and then you finish with images whithin those dark areas almost undistinguishable from each other. That would lead you to change EV settings manually, in order to get the exposure right.
On the other hand, using Spot metering may allow you to lock the exposure on those dark areas to priorize them, without having to ajust EV settings manually.
The thing is that sometimes the object on which you plan to lock the exposure may be far from the object you intend to focus on, so the latter ends up blurred. In that case I see no other way but use Normal metering and adjust manually the EV compensation (or in DM 3.5, ISO) settings.
Here it follows an example to illustrate that:
These first two were taken with Normal metering. Notice that no matter where I fix the focus (either at the front or at the rear of the mouse) the exposure settings are the same for both pics:
On the other hand, with Spot metering, If I fix the focus at the front I get one setting for exposure, while for the rear I get another:

Jake, could you please post more detailed info from those shots? It would be interesting to see it. I am curious to see them in their original size, too. I guess they are not that different from each other. I mean, look at the shadows on both pictures. They are almost equally lit. IMO the most noticeable differences are color saturation and contrast. The second one is way more saturated than the first one and also lacks some contrast.
Here's one more night shot from mine (this time resized). It was taken with the mixed Cybershot Xp + DM 3.5:

Hi Vit, I put the combination Xperience Cybershot 4.1 and DM 3.5 to my C905 with the English language, a question I can help with how to use manual settings options (2) and manual settings (1)? I see several new and nose how to use them or control them such as the ISO control, white balance, Part 2 and Part 1 (focus, contrast, saturation, effects), could guide me a bit? thanks |

No, no! Do not delete camera2.dat. That's the driver for the front camera. You should only replace the original camera0.dat with the new one. Just remember to use the command "read" before doing that, in order to backup your original driver.
I moved DM3.5 camdriver0.dat to my phone using A2 uploader. I switched off the phone and switched on.. i couldnt c any changes in the camera menu. did do smething wrong ? |

@ toxicneo
You need to copy the en.lng file to TPA/PRESET/SYSTEM/LANGUAGE so they say, but it still made no difference to the menus for me.

I did notice as soon as you edit a .lng file with LNG_Editor_0.0.1.3 it becomes unreadable. The languge is then not seen on the phones language menu. |

I still did not try to take a shot of a moving object at night or in low-light environment. What I observed with DM 3.8 is when taking night shots then adjusting shutter speed to +2.0EV, it brightens the scene like in adjusting the exposure. I am not good with technical terms in photography since I am not a photographer, I only try and test shots for the right settings of the camera. And I am still familiarizing with this new driver that is why I could not advise you what is the right settings in a certain scenario. I am only depending on my test shots.
As I've understand, when setting the shutter speed to +2.0, more light reaches the sensor since there is a longer time of exposing light to the sensor making the image brighter.
For photographers out there, can you help us with the terms in photography, maybe that will enlighten us somehow on what are the right settings to be used in taking shots... 
@Vit
Can you also post pictures taken indoors with low light?
Thanks...

I'm not a pro shooter, but, as I've written, even with DM 3.5, which sets ISO 100 for Twilight Landscape mode, what happens when we change EV values (on that particular mode) is increase/decreasing the exposure or, in other words, decrease the shutter speed. Take a look @ one of my last comments on the subject. Normally, when shooting in AUTO mode, changing EV values changes automatically both ISO and shutter speed. If you set ISO to a fixed value, there's only shutter speeds left to be changed.
As for the the brigthness of those pics, differences in contrast and brightness may be confused with differences in exposure times. That's why I asked for EXIF info on those shots. I guess those might be the differences between them, besides the most noticeable color saturation on the second one.
It also feels that Jake has confused the shots from his two posts. Look at the most saturated pictures of the two pairs of pics he's posted. In the first comparison, the most saturated one is labeled as DM 3.5, and in the second comparison is the contrary.
I will take some night indoor shots today with my mixed drivers, which have Twilight Landscapes modes based upon DM 3.5, and post them later here. I will take them with 3 different EV values, -2.0, 0.0 and +2.0.

@Vit
Hi,
thanks for all of the tips so far.
I did not confuse the 2 sets of comparison shots. You'll notice that the first set of shots were taken on all AUTO settings, and the next set were taken with twilight portrait mode.
I am not sure how DM tweaked the settings here, but this is the way the saturation came out on those shots for me.
Also, I am not taking a lot of shots and sorting through them to pick out the best quality ones which i know some people do here.. I am merely posting some comparison shots to help determine which driver is better/worse.
You are posting some very nice shots with your mixed mode driver, and I am VERY interested in this, but it would be more helpful if you explained what settings you used, and how to operate this "mixed mode" driver to achieve the quality in the shots you have posted here.
I have also updated my comparison shots with the detailed info.
i am looking forward to more shots from you
thanks!
