What happens at ISO 20000?

_DSC0878

What happens at ISO 20000? Well, pretty much a bit of grain. These photographs were taken with available light – believe me “available” is an overstatement. Two or three 40W lightbulbs, scattered along the stage, musicians moving all over the place. Even at f1.4 things were hard. So cranking up the ISO was basically the only way the get this right.

For those of us that still remember film, being able to record an event under this sort of circumstances with such detail and with this little amount of noise is a nothing short of a revolution.

If there is something the digital age has brought to us is the ability to still have your job done even under extremely difficult scenarios. Of course, speed, resolution and the lot also have improved.

All these photographs were taken at 20000 ISO. I know, you want to me let you know what camera did I use, lens and all that. Rest assured, there are a few cameras (and some of them aren’t full frame) that can do this. But, can you?

Are you brave enough to crank up the ISO and stop complaining? Try… you will be surprised.

Have a great 2018!

Escolhi esta fotografia de um peregrino, exausto depois de cumprir a sua promessa, junto à Capela das Aparições em Fátima em pleno 13 de Maio, para ilustrar sacrifício, dedicação e fé. Não necessariamente num credo em particular, em nenhum em especial. A Humanidade precisa, desesperadamente, de uma inversão de valores. Temos que deixar de endeusar os bens materiais, de ligar sucesso a dinheiro, a riqueza material. É crítico que a acumulação absurda de riqueza em meia dúzia de mãos termine e que haja mais justiça social, menos desigualdade, maior equilíbrio, através do trabalho e da responsabilização colectiva, valorizando atitudes proactivas, fazendo pleno uso da democracia. Fé, fé na humanidade, acreditar que somos capazes de travar esta espiral de ganância que coloca em perigo a sustentabilidade do planeta. Dedicação a causas comuns, espírito de corpo.

Feliz 2018!

Digital manipulation – What is and what isn’t

87Uelesmann1

Digital manipulation – what is and what isn’t?

Beyond ethics, what can we really consider as acceptable nowadays?

Before we speak about manipulation let’s not forget pure and plain lies. Many photographers have been caught lying about location, context, subject manipulation on their photographs – beforehand this is about ethics, has nothing to do with digital post processing.

In spite of the natural grey area this issue implicates I believe that to make matters simpler and easier there is a perspective we must consider, as long as we are familiar with the analogue/film process.

Plenty of times I read or engage in conversations where it is affirmed that almost everything one can do with Photoshop or with any other imaging editing software is digital manipulation. Well, it is not. For those that have no idea of what is possible within the analogue realm it is hard to realise that plenty of what we can achieve with Photoshop nowadays was also achievable using film development and/or enlarging techniques during the film era.

Just a glimpse of what was possible with film development: using different chemical solutions, altering dilution ratios, changing temperature of the diluted chemicals, increasing or decreasing development time resulted in changes in the shadow and highlight areas of the negative. Furthermore, the fine silver halide particles “changed” when exposed to different chemical combinations/brands, the output changing accordingly. But, even prior to this step we could expose a film one or two EV’s below or above its nominal sensitivity (ISO) changing dynamic range and therefore the shadow/highlight relationship and rendering. We could compensate for this in the development stage or increase the desired effect changing recommended development times.

Once the negative was ready to be enlarged a whole new frontier opened up: more or less sharpness could be achieved changing the aperture in the enlarger’s lens, cropping, recomposing, correction of converging/diverging lines, enhancing shadow or highlight areas using masks or overexposing certain parts of the image. This was a very long process, trial and error, undo was not possible. I spent hours and hours of my life locked inside the darkroom experimenting, enhancing and fine tuning my images. I have to confess that we’ve gained a lot with the digital process, our life being much easier today. Undo is probably the best command the digital era invented.

Last but not the least, print development was the last frontier. And again, different papers combined with different chemicals, temperatures and timing provided exceptionally different results. Selenium toning was just one of the final touches available, changing a print’s colour and making the image more permanent by bonding selenium particles directly to the metallic silver in the emulsion. There were a few different toners usable to finish the prints, all of them providing dissimilar results. The output of fibre-based or resin coated papers was also substantially distinctive.

Adams_The_Tetons_and_the_Snake_River

Ansel Adams book trilogy “The Camera”, “The Negative”, “The Print” is mandatory if you want to get to know (and learn) about the extraordinary potential of the analogue process. Ansel Adams was a master, second to none when it comes to exposure, development and printing techniques. “Manipulation” of the original image using analogue processes was absolutely mind blogging.

In my opinion, all that we could do to enhance and improve the original image back in those days was acceptable and therefore, my opinion again, acceptable nowadays within the digital medium. I do not consider digital manipulation everything that one can do to improve, enhance and potentiate the final result, starting from a RAW file (JPEG SOOC already have a considerable amount of manipulation/enhancement). I prefer to tag this process as “digital enhancement”, not manipulation. Jerry Uelsmann’s entire photographic carreer was based upon image manipulation using analogue techniques and his work demonstrates what was possible using analogue techniques to heavily manipulate one, or a set of photographs by creating a new reality, a completely new interpretation of a scene, clearly manipulated.

So before adding “digital” to this conversation I believe we must discern enhancement from manipulation. Putting this openly, Adams’ work is the epitome of enhancement and Uelsmann’s work is the embodiment of manipulation.

Of course, being unaware of the history, complexity and potential of the analogue process doesn’t help. Roots are always important, if not critical, for a better understanding of the present.

If you’re not adding or subtracting objects, subjects or any other items to the image or altering those that were present when the shutter was released I do not think you’ll be manipulating. If you’re using image editing software to crop, reframe, for perspective correction, to enhance shadows or recover highlights, to sharpen, to saturate or desaturate you’ll be enhancing the RAW file (the “negative”) and this is not manipulation.

O projecto que estamos a produzir para o Município de São Pedro do Sul e cuja conclusão se prevê para o Outono de 2018, inspira-se nas muito diversas mais valias do concelho – a maior estância termal da Península Ibérica e uma das maiores da Europa, a hotelaria de excelência que serve a cidade, a serra e a paisagem inimitável, a recuperação do balneário romano – que está em curso – e onde D. Afonso Henriques foi a banhos para tratar da sua perna partida.

L’Avalot – Teatro de Rua

_9010324-copiar

Há circunstâncias extraordinariamente difíceis para equipamento e fotógrafo. Quando se é amador (perdoem-me o abuso, nada tem que ver com o mérito de cada um) e “corre mal”, perdem-se imagens que tanto gostaríamos de ter registado com sucesso. Quem da fotografia faz profissão não pode falhar – o trabalho tem que ser entregue, com toda a qualidade exigível, no prazo acordado.

Uma das tarefas mais difíceis com que me deparei foi o registo da prestação da companhia de teatro L’Avalot (Barcelona), teatro de rua, itinerante, com grandes efeitos pirotécnicos… à noite. Muito pouca luz (ISO elevado), movimentos erráticos (AF), enormes diferenças entre luz e sombra (gama dinâmica), composição difícil (público a correr para acompanhar o “desfile” pelas ruas, de telemóvel em punho). O pesadelo perfeito.

São estes desafios que fazem, bastas vezes, a diferença entre o amador e/ou o fotógrafo menos treinado e (desculpem a imodéstia) o “seasoned photographer”. O conjunto de imagens produzido (publica-se pequena amostra) atesta também o “state-of-the-art” do equipamento actual.
