Interesting video, Andrew. I think I preferred the TD-3 developed neg to the Adotech IV one The former seemed to replicate the real contrast I saw in colour. The shadows on the large branch looked in "real life" as if someone had painted black stripes on the branch and TD-3 seemed to get closer to that look

PS you have been on more dangerous slopes about 30 years ago from what I saw of the angle of ladder and car roof Maybe baby Jeremy was wondering if mother had had the good sense to take out life insurance - just ín case

Actually, her mum took out life insurance on me

Was her usual greeting made with raised eyebrows and " Still here I see" said in a surprised voice

In the Film Developing Cookbook 2020 p134, referring to the use of TD-3, Bill Troop says:
"The best overall results are obtained when contrast is high enough to require grade 1 paper with a condenser enlarger or grade 2 paper with diffused light"
"TD-3 produces speed approximately double that of POTA types while significantly lowering granularity..."
So it looks like TD-3 results should be a bit better if you judge from prints not negatives.

I made Alt. prints for the next video.

Thanks for the comparison Andrew, I was just looking up more information on Adox CMS 20 II and Kodak Technical Pan and found they are quite different animals.

Tech Pan in TD-3 looks great of course, it's designed for it.
Tech Pan in Adotech seems a bit too high contrast but usable.
Tech Pan at EI 16 in Rodinal 1+150 13 minutes, 3 inversions every 3 minutes, looks very good.
CMS 20 in Rodinal even 1+200 stand developed is very high contrast.
CMS 20 in TD-3 I think also falls into a little too high contrast, but usable.
CMS 20 in Adotech is of course great.

Yup! Adotech IV is king of the castle. The only others that came close was a version of Caffenol, and POTA.

(Watching this on a lazy afternoon ...)

When you commented about forgetting a level, I thought "isn't there one on the iPhone?" And lo and behold it took a while to figure out where it's hidden ("Measure") -- there it was. (Obviously it's not in my frequently used list.) I'm irrationally guessing other smartische phones have a similar app.

(And yes, using the phone to level a large format beastie might prove a little less user friendly than a dedicated level of some sort. )

Anyway, up to your usual high standards for informative video.
Thanks.

For Android, a level app is something you have to download, but there are a number of pretty good ones that are free. I used my phone as a level just the other day, marking across from fitting marks while rehanging a half door to swing the opposite direction. Quicker than finding my actual torpedo level, and plenty accurate for the job (reads down to 0.1 degree inclination).

I have an Android. I did download a levelling app, but prefer my good old analogue level. I keep the one on my phone, just in case I lose my real level...
