Hey Vidyun, thanks for posting this. What did you learn from this experiment? I have a few questions to you.

1. Which flower did you like most? Which of these images has the color of the flower which is close to what you saw with your eyes?

2. Have you noticed how color of petals slightly changed from one image to the other? If you see carefully colors of the flower petals in the first image is richer in red compared to say 2 image in the second row (6th image), which you might have taken post lunch.

If you look at Red/Green/Blue intensity of these pixels you probably will see more blue component compared to the first one. In photography we call this "added color" which did not exist as you saw is called "color cast". That means the "real color" got shifted a bit due to quality of light
that changes during a day. Fortunately you can correct it in software like Photoshop. The issue is it will take some time to understand that an image has some color cast! Next time when you make an image, carefully keep an eye on the color
as you see and as it is seen later on your camera's LCD or on your computer screen. If you see there is a "color cast" you can correct it. You need to do this only if the color has slightly changed due to changing light!!

3. Did you notice that texture on the petals of the flower are different, say between the first image and the 6th image? The first image has nice details while the 6 image does not have it? We say the image has become "flat" (in this case 6th image). Can you think why it is so?
Tip: Try to understand what causes texture! Open the two images side by side in software and carefully see them larger. Look at very fine shadows caused by angle of the light on the petals of the flowers in two images!! You probably will see in one image it is more!!

Next time before you photograph, look at your subjects for a few minutes. Think about its color, light at that time, angle of light, texture. Think about best light and then try to make many images! Often we end up making mistakes. If you make a few more images
one or more will be come out great!! Along with photography carefully observe your subjects too. For example, the way spider builds its web. Why is it circular? Why not square? Who has taught spider to build it that way?! How many insects it might eat in a day?
How it builds its web?

Enjoy the nature and photography. There is a lot to learn.

1. I like the second flower in the second row the most. The most nearest colour is of the last one in the first row.
2. Yes Ganesh Mama, I have noticed. I had taken the 6th image at around 4.30 in the evening.
3. Yes Mama, I did notice that the texture is different. When I compared the first and the sixth flower, the first flower had a better texture. I think this is because it was taken in the early morning and the light was coming from the right side.

I will look into texture, colour, light and angle of light. Right know I know that spiders builds its web every morning, so when the lock down is over, I will go in the dawn and observe how it builds its web.

I will also try to read books about animals and insects. I will also watch videos about them.

I learnt that how we can see the patterns on the subjects. I had fun learning about RGB combination.

Hi Vidyun,

Nice to see you going out ( to balcony :) ) to try Ganesh's suggestion.

Keep the work going.
