The Future of Colour and B&W Film with Ilford...

[flavio81]

So class A really went out of fashion, finally. Energy bills caught up with the audio peeps as well?

I am reading this thread while listening to my Class A power amplifier, so I got a lot of fun when reading this.

Class A is as linear as it gets. However, the state of the art Class D designs are very good.

The setup I listen through the most is a little Philips TDA15xx on a custom PCB boxed inside a small enclosure and fed from a small USB adapter.

TDA1540 ? 1541? Those two are very, very good sounding chips in non-oversampling mode, proven that the surrounding circuitry is good too.

It receives an analog signal from the onboard sound card of my generic HP desktop computer.

How can the DAC receive an analog signal?

For me it's anything from Dark Jazz to Industrial Black Metal. Or nothing at all when hard thinking is involved.

Why not Dark Industrial Black Metal Jazz?

Listen to this and blow your mind:

It's not a DAC. It's an integrated amplifier IC, intended originally for car audio purposes. Back in the 1980s or so when it was conceived.

There's this parallel between photography and music/audio. In both domains, we see people fussing endlessly over the line the connects the creative art to its consumption. In my view, the closer you get to the end points, the more it matters. The stuff in the middle is the least interesting. In both music and photography, the artist's vision is the main determinant if it's worth spending any time on to begin with. Then there are quasi-technical choices like composition and orchestration that matter, and performance in music. At the other extreme, if someone is visually impaired or only hears a certain part of the spectrum, a lot of the 'fidelity' is lost anyway. If people view prints under dollar-store LED bulbs intended for a clothes cabinet or listen to music on $10 computer speakers, or in a room where the speakers are positioned in such a way that acoustic destroy any fidelity to begin with, what does it matter what happens on the wire/process in between those end points?

Yet, virtually all of the talk on photo forums as well as DIY audio focuses on the wire.

Nicely formulated. Gives a good analysis of what people are doing on forums.

This indeed it will suffice when HP5+ gives me trash @1600, trying to have something worthwhile with Ilford Reversal - perfectly captures the struggle: the hopeful beginning and bravado, followed by frustration and smashed chemistry bottles, ending in cacophony of futility, acceptance... and rebirth of the struggle!

I think it’s because enthusiasts enjoy the craft as well as the art, and judging by the incredible quality of the prints I see in museums a fair few master photographers (or at least their printers if not the same) were also obsessive about their craft.

Getting us back on track... I opened up my film fridge as well as the freezer, and the majority of film in there is Ilford, including Phoenix. Another brick of 120 Kentmere 200 arrived yesterday, as well as a brick of the 400. Running out of space! So many Ilford options to choose from!

I have no idea what you're talking about. There's always room in the film fridge

 

[DREW WILEY]

But how long was it till the Phoenix bird actually came back from the dead? A thousand years, or something like that?
That's a long, long time to leave the film in the refrigerator till you can actually use it.

Oh! I read "TDA15xx" and I immediatelly asummed you were talking about the TDA1540 or TDA1541, famous DAC chips by Philips.

I didn't know there were some Philips chip amps that also started with "TDA15". Until today.

Lol!! Glad you liked it.

HP5 works perfectly at 1600 with Microphen. But on negative, that is... Reversal, that's going against laws of nature. It seems that for some arcane reason it is hard to get high speed reversal films in general, the fastest i've heard of was Fuji MS 100/1000 which had a real ISO of 100, Scotchchrome 1000 and 640T.

By the way, is "Ivo Stunga" a play on "Ivan Stang" (founder of the Church of the Subgenius)?

Praise "Bob"!

It's just my name.
And Kentmere 100 @400 works fine, even @800 you have a decent image. HP5+ @400 works too, but pushing it to 1600 and maintaining contrast and DMAX with Ilford Reversal - a challenge to say the least. I still have a few moves in mind before putting HP5+@1600 idea to rest. It's perfectly usable @400 and shines in hard contrast situations, making it a solid choice as an URBEX film.

Double X 200 works good, so does SFX 200, Fomapan 200 and Kentmere 400...
