Cat In The Hat Life Size Cutouts

Negativ/Positiv Entwicklung ( 1.mal )

Hier findet ihr  schon mal eine Anleitung zu meiner ersten Negativentwicklung:

http://dunkelkammerblog.blogspot.com/2011/01/meine-erste-entwicklung-negativ.html

positive development:

The first is a completely dark room condition which I get when I tape over the bathroom window with a hardboard, keyhole cracks and residual light covers.

Since I always work in the bathroom I always have access to water.

darkroom lighting is also very important, I have a little bit rumgestestet and bought from the hardware store, an LED bulb with E27 base (eg Philips, Paul Mann 0.6W ect.) In any case, a red LED (green have I have not tested) NEITHER PARTY BULB!
order was to save money buying a damp basement lamp (1.99 € ) Which is screwed to a wooden bracket.
cable finished it. (Saves ever real money since a darkroom bulb costs about 12 € and then the housing and used again about 10 €)


the enlarger I have placed on the washing machine exactly Like all other devices (timer) so that here there is no risk from water / electricity.
A 12mm chipboard on the bath serves as a storage area for the three shells etc.

The shells I got from the hardware store is about 20x30cm perfect for small photos. (Shells from the photo field are outrageously expensive)

now mixes her your chemicals. (At 20 ° C temperature of the liquid)
I use a cheap paper developer sufficient for the beginning (Classic PNB) in a ratio of 1 / 7 for 500ml total amount of liquid that is at I 62.5 ml of developer and 438ml water.
the photosensitive paper is then between 60-90sec. in the Papierentwicklunslösung lie, it is easily swung back and forth (every 2 sec approx)

intermediate washing in the bowl about 1-2min.

fixer I use Tental Superfix at 1 / 4 would, in my fixer 100ml and 400ml water.
is fixed between 60-90 sec.dabei auch wieder ab und an leicht schwenken.
Anschließend nochmals gründlich Wässern (2-3min ).

Die fertigen Fotos hänge ich an einer Leine auf die ich mir gespannt habe.

Das hier beschriebene Verfahren ist mein erster Versuch gewesen und hat schon super geklappt finde ich , natürlich ist es was Material angeht und Sauberkeit verbesserungswürdig aber alles Schritt für Schritt .

Nun zum Dunkelkammertest, indem man schauen kann ob der Raum auch optimal präpariert ist und kein Licht eintritt.
Man legt im dunklen Raum ein Blatt Fotopapier auf der Grundplatte des Vergrößererś  (Achtung Fotopapier ist extrem Lichtempfindlich dementsprechend only seen in a dark room! ) And then a coin on top.
Now you wait 4-5 minutes off without touching the coin / paper.
The paper is now being developed in the above-described liquids.
is no longer a mark of the coin there is your room light tight.
The same test makes it to the darkroom lamp (in the on
state) so that you can exclude any source of error and gives the lamp is no stray light that you cast a veil on this paper or completely destroyed.

have photo paper as I Adox 311 Easy Print 10x15 concern in multi-grade (can filter contrasts with the more or gelatin fewer imprinted). Do not lay on top
Then once plain paper in 13x18 hardness Normal

This paper curl if you can it exposed to the enlarger her a glass pane that you save the expensive acquisition of a magnifying cassette.

To find out how long you have to expose the paper, I suggest a test: negative in the enlarger

A sheet photo paper covered the lie about 2cm open
device 2 seconds then turn it off.
stripes put another 2 cm open.
exposure 2 sec.
2 cm. disclose
2 sec exposure
All this makes her so about 6 times und dann entwickelt ihr den Streifen.
Anschließend schaut ihr euch die Bereiche an und entscheidet was für euch optisch am ansehlichsten ist bzw. am neutralsten (je nach dem was man als Ergebnis wünscht.Wenn es das vierte Feld ist dann müßt ihr 4x2 sec. multiplizieren und damit habt ihr eine Belichtungszeit von 8 sec.
(die Zeit ist abhängig von der eingestellten Blende und dem Abstand des Objektives)

Wenn ihr die Fotos zum trocknen aufgehängt habt achtet darauf das so wenig wie Möglich Staub auf eure Bilder fällt. !!!
