Light Painting

 

I was really happy with the way my light painting turned out, especially the last photo. My goal was to paint a heart and i succeeded. The hearts in the last photo look almost perfect, but its hard to remember whether i painted slower or faster. This technique is still definitely tricky snd not achieved perfect yet.

Save the pixels

For one subject shoot at ISO 400, shoot three images:

In my opinion the best exposure given is the second photo at 1/15th of a second. It’s not exactly the brightest but a tad brighter than the first photo and  it sure beats the two other photos. Those ones are definitely darker.

I am going to say the one with the more noise is the first photo because to begin with, as you zoom in 100% it is blurry.

For a second subject shoot at ISO 1600. Shoot two images:

For the first image I stayed at 1/20th but it obviously looks too exposed at ISO 1600

For the second photo I had to go two stops higher than 1/20th to 1/45th of a second. At ISO 1600 it looks much better than the first.

This one is one stop under exposed at 1/90th of a second. Since we were by the window u can see that her right side has a little more light and that there is a lot of shadow on her left side.

I feel as if the third photo has the most noise because it is also the darkest out of all.

For a third subject. Shoot two images:

  1. One in raw:

One in jpeg:

I feel as if the second photo has more noise because it is the darkest one. you can definitely see more noise in her eyes. There is light coming from her right side because of the window next to us but there is a lot of shadow on her left side. Ps. the raw file couldn’t be uploading here due to its form.

 

 

Histograms

Light Tones

As you see in the histogram, the graph rears through the right side almost at the end of it and it is very high. Lots of grey in the histogram.

Mid Tones

IMG_5206.jpg

As you see in this histogram there is less grey and more blue but red has ben slightly added which was not apparent in the first histogram. This histogram is going towards the beginning middle.

Dark scene

In this histogram, there is more grey apparent and blue. Less red, no pink like the first histogram and a bit of yellow. The histogram is reared towards the start of the left.

Noise Reduction

Iso 100 1/4 f/22 Low noise reduction

My camera is very outdated and causes a lot of noise. you will be seeing some noise in the photos below. There is also dust in my sensor so you will be seeing some spots in these photos. I feel like the strong noise reduction setting takes out the most noise reduction. At 3200 staying at 1/4 it got way too bright so I had to take it to 1/10.

I understand now exactly what you wanted, the photos needed to be properly exposed even though at different Iso’s the aperture would be different but look the same as the rest of the photos.

Iso 100 1/4 f/22 standard reduction

Here the paintings look more sharper with less noise than the first photo.

Screen Shot 2017-02-22 at 11.00.31.png

Iso 100 1/4 f/22 low noise here the paintings look less sharp.

Iso 800 1/4 f/22 low reduction

Screen Shot 2017-02-22 at 11.05.30.png

Iso 800 1/4 f/22 standard reduction, both photos look relatively the same in noise reduction and sharpness.

Iso 800 14 f/22 Strong noise reduction

Screen Shot 2017-02-22 at 11.07.34.png

Iso 3200 1/10 low reduction all these photos at iso 33200 seem tok be high in noise.

Iso 3200 1/10 f/22 standard reduction ;pals rarely the same as the first photo above.

Iso 3200 , 1/10 f/22 high noise reduction, this one seemed to be higher in noise than the rest.
