Color Gels - Day 15

Today I've made a test of all the color gels that was delivered with the HONL kit of light modifies for Nikon Speedlight. Here is the set I bought:

All items fit into a small black bag. It contains two large modifies in gold, silver and black that can be shaped like a snoot or a bounce card, a smaller light modified in silver, two barn doors in white and gold, two honeycomb grids, two speedstraps and a set of color gels - two of each color. 

Okay - I chose a simple set-up. A white piece of paper, where i placed a small white sculpture. My Nikon D300 with AF-S 18-70mm f/3.5-4.5G ED lens was mounted on a tripod. A SP-900 was connected to the camera with a SC-29 cable enabling me to handhold the flash and control the light path. 

Color correction is a process used photography and other disciplines, the intention of which is to alter the overall color of the light. Without color correction gels, a scene may have a mix of various colors. Applying color correction gels in front of light sources can alter the color of the various light sources to match.
Gels are also used to make a scene appear more natural by simulating the mix of color temperatures that occur naturally. Color gels may also be used to tint lights for artistic effect, which is what I have done in this little test.

Let's start with a photo without any color gel - just the honeycomb grid (narrow beam). I have made no alteration to the photo in LR.

From now on I referring to the names that HONL has given their gels.

Just Blue:

1/2 CTB (Color Temperature Blue):

Moss Green:

Full +Green:

Bright Red:

Medium Yellow:

Heavy Frost:

1/4 CTO (Color Temperature Orange):

1/2 CTO (Color Temperature Orange):

1/1 CTO (Color Temperature Orange):

The main color correction gels are CTB (Color Temperature Blue) and CTO (Color Temperature Orange). A CTB gel converts tungsten light of 3200K to 'daylight' color. A CTO gel performs the reverse. Gels that remove the green cast of fluorescent lights are called minus green. Gels that add a green cast are called plus green. A 1/2 CTO gel is half the strength of a (full) CTO gel.

I've just ordered a new book from Amazon. The name "x-teams" immediately caught my eye as I read about it in the Danish business newspaper - Børsen. The reviewer assigned 5 marks out of six, so expectations are high.
X-Teams written by Deborah Ancona and Henrik Bresman raises an interesting question already on the front cover.
"Why do teams fail?"
The topic of the book is how to build teams that lead, innovate, and succeed. I'll write a short review as soon as I've read it.

SnapScan 9000 - be prepared for a laugh

Can you guess who the nice young man is in the image? It is me as a high school student - important years - where my passion for photography really took off. My god - 35 years has passed since those happy years.

I have just scanned b/w negatives and color slides from these years, and it has been hilarious to see the pictures again. Since many of the images are not something to boast about, the mission was only to get the old negatives and slides converted to digital format. Since I have many pictures from my analog years this conversion process must also go quickly.

Therefore I have just tested JOBO Snapscan 9000. It took med just 5 minutes to unpack it and set up. The scanning process is extremely simple. You install an SD card in the scanner, and then feed negatives or slides into the scanner by the help of various rails and frames - one at a time. The scan process only takes 4 seconds per negative / slide. The scanner has some simple correction options such as built-in color corre…
