This can be confusing because people sometimes use different terms to try and explain the same concept.
Anytime there is measurement involved, confusion often follows.
Watch the video and let me know if my approach is clear.

How would you prepare 1000ml of a 1:100 dilution for PyroHD?
Step 1: Determine the required ratio by dividing final volume by dilution factor: 1000ml/100 = 10ml (developer)
In this case we know that we want to mix 1000ml of PyroHD and we want it diluted at 1:100.
Step 2: Subtract the ratio volume from the final volume: 1000ml - 10ml = 990ml (water)
Step 3: Measure out 990ml of water, add 10ml PyroHD developer to it, mix thoroughly
It really is that simple.
Here is another example using a different dilution so you can practice.
Try and figure out the two parts (developer and water) for the dilution before looking at the answer to make sure you understand how to use the process.

Dilute HC110 1:63
final vol / dil factor
1- 500ml/63 dilution factor = 8ml (developer)
2 - 500ml - 8ml = 492 (water)
3 - mix two together and enjoy!
Dilute Stop Bath 1:19
final vol / dil factor
1- 500ml/19 dilution factor = 26ml (stop bath chemical)
2 = 500ml - 26ml = 474ml (water)
3 - mix the two together
What Are Art Buyers & Collectors Saying About Tim Layton Fine Art?
I want other people to know the attention to detail that Tim puts into the making of his fine art.
As a fellow large format photographer and printer of my own B&W darkroom prints, I can tell you that Tim’s work is exceptional.
Now having this print in my hands, I can tell you that this selenium-toned print looks three-dimensional. That is high praise considering we work in a two dimensional medium. If you have not already joined Tim’s Fine Art Print Club, I strongly recommend that you join now! You will not regret your decision. -John D'Angelo, NY
"The size of your prints are amazing, but it’s the minute detail and tonal range you capture that give your images their aesthetic qualities. Every one of your handmade fine art prints that I have seen, has blown me away to the point I pause the video to look at them more closely. It never ceases to amaze me how you create images that look so simple, and yet many of us watching that doesn’t mean easy. I can only dream of capturing anything 1/10th as beautiful as you do." -Mark Harris
Keep up the good work Tim, love your work and contribution to conservation" -Rodney Rudman, Cape Town, South Africa
"The artwork by Tim Layton is very unique, all handmade, from the negative to the final print on Ilford MGIV fiber paper and gently toned in selenium. The tones are subtle, and distinct, and placed in just the right grey scale zones so the overall contrast of the print feels complete - from pitch black to delicate highlights. Holding one of his prints in your hands and viewing it carefully in daylight will reveal the beauty of his handmade darkroom prints. In addition, Tim's prints are simply beautiful and artistic." -Anders Blomqvist, Sweden

What Are Members Saying About The Darkroom Underground?
There is no shortage of people providing information on photography on YouTube and the internet. Some are even aimed at the analog photographer, but what Tim has done with the Darkroom Underground (DU) is nothing short of pure brilliance. DU is not only for the analog photographer it is also for the Large Format & Ultra Large Format Photographer. I don’t know of anyone else who is covering ULF.
He has simplified learning with wonderful videos that are supplemented with show notes so you have all the information for you to do this on your own. But unlike anything else out there you have Tim as a resource, too. He has always been easily available for questions or clarification and he welcomes suggestions for future shows.
If you are serious about learning all aspects of analog and LF/ULF this is the place to be. -Michael Wellman
The videos and blogs are shot and edited in a very professional way. Tim is always ready to receive and share the suggestions and ideas coming from other people. He is a very good community manager.
I would like also to underline the growing role of his son, Tim Junior who contributes also greatly to the quality of the videos, text and explanation. Last but not least, Tim is always welcoming suggestions and questions and ready to interact. I recommend warmly the work of Tim Layton. -Stéfane France
