The high contrast exposure affects every part of the print. If you increase the high contrast time, every part gets darker.What I want to know if this has a limit? For example will it affect the other parts of the print and such?
Okay, fair enough. But let's say I have this print which is very dark grey and with single grade I cannot get the right amount of blacks because else the highlights would suffer.
With split grade I could increase the exposure until that dark grey hits maximum black. No?

Another side question: If you do single grade printing and have to use an extreme like grade 5. Which only affect the blue sensitive parts. Let's assume you have a decent amount of highlight detail. Printing on grade 5 won't reveal those because there is no green light for the low contrast stuff. Is this a valid conclusion?
Because when printing at grade 5 you still get some decent detail in the highlights and such. Even though it's said that it will not affect green sensitive parts?
The high contrast exposure affects every part of the print. If you increase the high contrast time, every part gets darker.
However, the amount each part gets darker will vary with the intensity of the light that hits the paper - i.e. with the density of the part of the negative that corresponds with it.
Once the darkest part of the subject reaches maximum black, you can't make it any darker, so lengthening the high contrast exposure time won't affect that. But, the other parts of the subject which were formerly lighter than that darkest part will get darker when the high contrast time is increased, so they may start to block up and become indistinguishable in tone from the other fully dark parts. In other words, the contrast in the dark areas goes down, because more and more of the print is the same, indistinguishable maximum black. If you continue increasing the high contrast time, eventually the whole print will have no contrast - it will just be a black blob.
If you've got a negative which seems to print very grey and flat at normal (2 or 3) filtration, you can often get deeper blacks in certain areas by selectively burning those areas at a higher filtration. If you're starting with an underexposed or underdeveloped negative, this can make things more difficult because you have less tonal separation from all the shades of grey to black. It becomes tough to keep those subtle greys separated without everything going too dark. Unless you like that look of extreme separation between light and dark, which I happen to love in some cases. Google - Daido Moriyama "Stray Dog" for a good example.
For your side question - yes, for the most part. I have had many negatives where I didn't see all of the detail in the highlights until I did a test print at grade 0 or 1. Especially for areas like the sky, where there may be some cloud detail I'd like to emphasize. Before I start working on printing a negative, I do a test print between grade 2 and 3 for an overall assessment, another one at a higher grade if I want to get a feel for the image with more contrast, and another at a lower grade to try to bring out the highlight details. I use these to plan out my filtration scheme, and any burning or dodging I may want to do at different grades. The "Tower Door" image I showed earlier probably took me a week to get a print I was happy with. Other negatives have taken me months to finally figure out.
Printing at grade 4 or 5 only will often fail to show much of the detail in the highlight areas, if there is any. It all depends what's on the negative.
Here's an example of a print that came very easily - TMax100 developed in D-76 1:1 with normal development. Printed at grade 2.5 with no dodging, burning or split-grade needed. It was just a well-exposed negative that gave me that feeling of "light" I was trying to capture.

Basically, you are asking how the contrast of the negative is converted to contrast on the paper with VC-paper, right?
....
In your Berlin scene, you have encountered a simple problem: The negative in total has a high contrast, with two main areas of low local contrast (the shadows in the front and the sky). So you need to print the two different areas in separate steps with individual exposure time & grading.
... So, actually a single grade print at grade 5 shows less detail in the highlights than eg. a split grade print which still does some exposure at grade 0. Effectively making a sort of HDR picture ...
Jesse,
Keep in mind that adding an overall grade 0 exposure to an overall grade 5 exposure is exactly the same as a single exposure somewhere less than grade 5. There's no free lunch here. What you can do easily with split-grade printing, however, is give different areas of the print a different contrast setting by selectively adding high-contrast or low contrast exposure to certain areas (burning with a high/low filter) or subtracting high or low contrast exposure from certain areas (dodging during high/low filter exposure). If your sky looks better with an extra exposure of "0" filtration, then it needed a) more exposure and b) less contrast.
And, back to the original premise: if your grade 5 print looks better with some grade 0 exposure figured in, then it looks better with less contrast (i.e., grade 5 was too contrasty).
Part of the difficulty with split-grade printing is understanding whether you need more/less contrast (different filtration) or more/less exposure (burning/dodging) or a combination of the two (dodging/burning with a high/low contrast filter).
If I were printing your shot on graded paper (fixed contrast grade) then, after I arrived at the contrast grade I wished to work with, I would find separate exposure times for the foreground and sky areas (i.e., dodge and burn as needed) to get optimum exposure in both areas. This is actually fairly common. With split-grade techniques, you have the option of treating these two areas with different degrees of contrast (between 00 and 5 anyway) as well. Therein lies the advantage of split-grade printing.

Remember, you use changes in contrast to control how details are rendered, not to control how light or dark those details are. Also, split contrast printing only really comes to its own if you use different contrasts for different parts of the image.
Mhm. First time I read it like this. Seems that I got one of the fundamentals wrong?
What I learned is that you get the exposure you nees for example skintones in a portrait and use the grade to darken the shadows/blacks. Like if the hair is too grey, go a grade higher and voila, darker hair. But this seems to be wrong?
Although I'm don't think the Berlin scene is a high contrast scene. Yes the sky and foreground is light grey and very dark/grey black. So if I wanted to print the picture at a single grade. I would choose an exposure for the sky and if it would have been high contrast.. the shadows would probably have ben blocked. But if I print this negative at grade 2. The shadows look dull, grey to dark grey. No real blacks. Which means that the density of the highlights aren't that thick right? So the negative density range is quite low = low contrast print. So it's not a high contrast scene? Or am I wrong?

Jesse,
Matt pretty well answered for me (thanks Matt)so I can elaborate on something else. Matt stated it well:
When starting out, we tend to think of "contrast" as blacks and whites in a print. This is really just the brightness range. Contrast, better understood, is the degree of (density) difference between tones. Imagine you have a negative with just two grey midtones, pretty close to each other. Now, you can print these at a number of different contrast settings (0-5) and you'll get more separation between the tones in the print as the setting moves toward more contrasty.
Often, we have a negative that screams for lots of separation for a particular part of the image. Let's say we have a scene with a wooden building, white clouds and some very dark, shaded parts. Now I can print this so the blacks in the shaded part of the image are black in the print and so that the clouds are white. That's fitting the overall subject brightness range into the range of the paper by adjusting contrast. That's Mark's "photofinisher" approach. However, I might look at the wood on the building and decide that it would look a lot better with more texture, more separation between those close tones, i.e., more local contrast. The only way to get this is to print at a higher contrast setting (or paper grade... more later about graded papers).
So, I choose a higher contrast setting; one that makes the wood look like I want it to. But now, the whites are blown out and the blacks are blocked up. What to do? Here's where we can get creative! First choice is to just dodge and burn, which amounts to giving the whites more exposure and the blacks less exposure to get them to appear how I want them. At this point, we've given our print three different exposures and we see that it is exposure, not contrast, that determines what is black and what is white in a print.
We could go on to refine this a lot more, by doing even more dodging and burning, giving graduated exposures to parts of the print, etc., etc. But then, we might find that the clouds, even though exposed "correctly" now, are too contrasty. So we decide to do our burning of the clouds at a lower contrast setting. And maybe the shadows still look muddy, so we want to up the contrast there. So, we end up dodging the shadows even more than needed, and then burning them back with a high-contrast filter. Now we have a print with multiple exposure times and multiple contrast settings. We like it now!
As for graded papers: Many of us learned on premium graded papers before VC papers existed or were deemed good enough for fine prints. There are still some things that graded papers do better than VC papers (nuances of tonality in the mid-tones, toning characteristics, image tone, etc.) and I still do a lot of my printing on Ilford Galerie and the Foma and Slavich graded papers. With graded papers, you don't have the option of having areas of different inherent contrast on one print; you basically have to live with the single contrast grade of the paper you choose. When I print on graded paper, I make an educated guess about which contrast grade I want (I usually indicate which contrast grade to start with when I make the exposure...). I then make a test strip, find my exposure based on the highlights and then make a straight test print. I evaluate this to see if I want to change contrast. If so, I make another test strip, find my exposure and then make another test print. If I need an intermediate contrast, I'll mix up a soft-working developer and spend time determining how long I should develop in the soft developer and then in the contrastier developer. This all sounds like more work than working with VC paper, but it really isn't. Making small changes in filtration with VC papers requires a change in exposure and more test prints as well. Sometimes, this is more work and more of a headache than dealing with graded paper, for me, anyway.
Currently, I tend to print on graded paper first and only move to VC when I need contrast grades outside the limitations of the graded papers (Most graded papers are only available in grades 2 and 3, sometimes 4), or when I need to split-grade print.
Best,
Doremus
If I may interject, I think OP needs to first take a step back from split grade, begin with some sound basics, and proceed from there. Often in this type of thread it seems to me that local contrast and local exposure adjustments are being confused/mixed up. Split grade (a specific case of variable contrast printing) doesn't seem to be well understood. It is my belief particularly where one is less experienced, that printing should proceed in a more logical manner.
"I followed a tutorial by accident 2 years ago, by some guy named Taylan on YouTube. He had a darkroom in Turkey. Watching the video learned me only those two things. Expose until the skin tones looked good and adjust the grade if your blacks are too low or too high. Too high: lower contrast. Too low: higher contrast"
This makes sense when the choice of grade is an one grade for the entire picture.
If the photograph you have to print is really two pictures (or more) in one (like the one we are talking about) then you need to combine the effect of different tools for each of the areas that require different treatment.
I hope that this lack of understanding is due to the differences in geography and language between us, and not because Doremus and I are just too oldWhat is a "photofinisher"

A photofinisher is a volume based commercial processing lab. Someone who one might send all their rolls of film with holiday, birthday party and other low importance shots on - basically the sort of lab that 90% of people who took photographs used to use when everybody used film.
Busy photofinishers would develop and print hundreds or thousands of rolls each day.
a great subject in bad light makes a bad photograph
However I'm trying to read some books like way beyond monochrome. To check out what split grading actually provides.
