Bridge Over the American River Near Sacramento. in tiny holdings, give each and every proof of a very rap-idly increasing population. The road enters Sacramento after crossing theAmerican River. This it does on a composite Howetruss bridge. In getting into Sacramento extremely much thesame situation is encountered as that at Marysville.It is essential to go by way of a levee. Wing-leveesare constructed to allow of this entrance. At the lowest pointof the cut, at the center of the levee, it has been foundthat water would seep by means of from the river andcollect in the cut. Provision to obviate this has beenmade by installing a little motor-operated pumpingrig. The cut is heavily constructed with concrete piers and wing walls and supports numerous railroadtracks, laid lengthwise of the levee. Inside the city the road has a double track andpasses via a number of streets until the passen-ger terminal at Eighth and J streets is reached. Thereis a Y provided right here to enable the turning aroundof cars or trains. Quickly

Acabei de montar o Standard/RedScale PinProject, vulgo &quotNaManteiga&quot e ainda não obtive os resultados. A idéia que produzir fotos Normais, RedScale e até mesmo Dupla Exposição (simultânea ou não) com a combinação dos dois modos. Deus queira que funcione.

1 – Buraco do lado Regular. Atenção, devemos adaptar o alumínio de cerveja no quadradinho aberto na lata. O aço da lata é duro demais e não recomendo ninguém fazer o pinhole na própria lata. Faça por sua conta e risco, se quiser. Cuidado com explosões.

two – Buraco do lado RedScale. O chamado processo RedScale ocorre ao expormos o filme á partir da face contrária. Em função de problema de filtragem dos espectros da luz temos um efeito avermelhado como resultado dessas fotografias.

three – Filme vazio. Ali no six temos a seta que indica o sentido de avanço da película.

four – Filme cheio. Na cabeça do eixo central desse filme devemos fazer a marcação que servirá de guia para o avanço de cada frame. Uma volta completa é suficiente para termos a estenopéica pronta para o próximo disparo.

five – Neighborhood onde percorre o filme em direção ao &quotfilme vazio&quot

7 – Seta de indicação do lado Standard. Serve também para mirarmos o alvo.

eight – Obturador/lente do lado RedScale.

9 – Fase inicial do processo de fabricação. Todo cuidado é pouco para não se cortar, tanto na faca quanto no aço da lata. Após o corte devemos virar as bordas para neutralizar locais cortantes.

10 – Fase intermediária, após instalação do filme. Nesse momento devemos marcar a filme vazio, para evitar se confundir mais adiante. Ah, devemos pintar o interiror da lata com tinta preta fosco ou cobrir tudo com fita isolante.

11 – Vista superior da pinHole.

I just mount the Standard / RedScale PinProject , vulgar &quotNaManteiga&quot and not but received the results. The concept to generate Normais photos, and even RedScale Double Exposure (simultaneous or not) with the mixture of the two modes. God wants to work.

1 – Hole on the Standard. Consideration need to adapt the aluminum beer cans in the boxes open. The steel of the can is too challenging and do not suggest any person do the pinhole in the tin. Do at your personal threat, if you want. Beware of explosions.

2 – Hole RedScale side. The method known as RedScale occurs when exposing the film from the opposite side. Based on the problem of filtering the spectra of light have an impact as a outcome of these reddish pictures.

3 – Film empty. Here we have six in the arrow indicating the direction of advancement of the film.

four – Complete Movie. As head of the central axis of the film should do the marking will serve as a guide for the advancement of every single frame. A complete turn is enough to have the estenopéica prepared for the subsequent shot.

five – Location the film runs toward the &quotempty film&quot

7 – Arrow to indicate the normal side. It also serves to mirarmos the target.

eight – Shutter / Lens RedScale side.

9 – Early stage of the manufacturing procedure. All care is just not to cut in each the knife as the steel of tin. Following cutting the edges ought to turn to neutralize neighborhood cutting.

10 – intermediate stage, following installation of the film. At this time we should make a film empty, is to steer clear of confusion later. Ah, the interiror ought to paint the can with matte black paint or cover it with tape.

11 – Top view of pinHole.
