## Results

In our experiment, we take three groups of LDR pictures and try to construct three HDR pictures from them. For each group of these pictures, we take 6 LDR pictures with different exposure times. We’ll display the response curve for each color channel: red, blue and green and our final HDR picture.

## Group 1

Comment: It’s impressive to see the details both of the light and of the clothes. For these kind of pictures, it’s always easy to lose the details of the light since the pixel values of the area around the light will get saturated. But, through HDR, we could keep the details of the light without losing any other details.

## Group 2

Comment: Once again, we almost see the details of the lamb. Although it’s distorted a bit, we know there’s something in it, instead of just completely white for the whole area. What’s amazing is that we could clearly see what’s going on in the background. All the details of the bags are clearly revealed.

## Group 3

Comment: Once again, we could see a lot of details both in over-exposed area and in under-exposed area. For example, we could see some words on the white container on the right hand side of the lamb. It’s impossible for us to see those words when we take a picture with relatively large exposure time. Similarly, we could see the details in the dark area. For example, we could see that there’s a purple/blue stuff lying on the black bag. However, it’s likely that we’ll barely see it when the exposure time of the picture is relatively small.

Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
can nanotechnology change the direction of the face of the world
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
the Beer law works very well for dilute solutions but fails for very high concentrations. why?
