Some say that the books you choose to read give a clue to who you are. I suppose my choice of gear speaks a bit for myself and for who I am: an aspiring amateur photographer with a passion for nature photography. Walking on the beach with the waves running through my feet or on the Sintra woods I find joy, a refuge, the inspiration to let the right side of my brain run loose. If my photos have a mission, it is to convey a mood and present the viewed scenes and environments in an interesting way.
I don't abide by fashion, trends or artistic movements, I just follow my personal vision.



Just as a reminder for something that should be obvious, public doesn't mean free. All pictures in my stream are under full copyright. Nothing justifies its use without a contract or a written permission.

Pavel M says:
"Everybody can readily see that Luís is a first class photographer. All you have to do is to look a t a few of his photos. That is in itself a lot, but it would not be enough for me to write a testimonial.
As Reathel and others before me noted in their testimonials, Luís has this wonderful mix of kindness combined with incisive photographic judgement. You can rely on Luís to give you an informed, competent, factual, actionable feedback that many serious photographers need and seek. I certainly do. Luís helped me grow early on when some others of his caliber were not ready to offer a helping hand. I value that. For me, Luís is one of the pillars of PP that keeps the standards high and who gives the group its spirit.
Some of my comments are well meant and intended to be actionable and constructive but they are sometimes tough. I have a sense that Luís understands the constructive intent and that he takes criticism well. Luís is one of the few people on PP that I value the most and that makes me always come back.
Thank you Luís"24th December, 2010

"Honestly, I think Luis is one of the best photographer on Flickr. It's not only words, it's a statement. His landscapes are just magnificient. His black & white series hold a true sense of composition and a real storytelling... Storytelling... Something quite rare here. Only a few hold his talent.
I wish you the very best Luis."6th August, 2010

reathel says:
"I want to share what Luis means to me. I had become disillusioned with Flickr when I met Luis. He opened up a world of people who were interested in building relationships through sharing their photographic vision. His vision in particular is an inspiration. Each photograph he shares is well thought out and full of meaning.
Luis though is much more than a talented photographer, he is a genuine human being in the best sense of the term. He shows a love for his craft and a love for sharing his experiences and thoughts with other Flickr members in the most constructive way. He has been an example to me of what is best about Flickr and people in general.
I'd be proud to have a print of his on my wall and even more happy to share some early morning coffee on the way to one of his favorite beaches.
Thanks Luis."11th May, 2010

"Luis is one of the wonderful photographer in the Flickr that inspire me. His seascape and macro shots are always my source of inspiration. His marvelous work of Macro correct my perception that Macro is nothing but tons of boring, vivid close-up flooded flickr. I started to appreciate how the macro can be very beautiful and artistic.
I've learned a lot seeing his photos. I really enjoy his vision of the world; a passion for photography. Luis is generous, unpretentious and talented. I also respect the way how he treats his Flickr friends. You are such a wonderful person. Thank you so much."11th August, 2009

"Tive o prazer de o conhecer pessoalmente,em Julho de 2008, num dos primeiros encontros Flickerianos, aqui em Lisboa.
Descrevê-lo, só por imagens, mas apenas pelas suas belas imagens, lindas e suaves, com que nos brinda diáriamente!
Um forte abraço!"3rd January, 2009

gregor H says:
"Sometimes, when I watch a picture I feel inspired and find a deeper message while thinking at it. This has happened to me with your pictures, Luís. I mean, it comes close to real life! Because of that, those pictures become an inspiring example and help me developing my photographic skills. I also highly appreciate Luís comments. His words show me my own work from a different viewing angle. Thank you Luís for your friendship and for inspiring me."

"Luis is a master of photography in natural light and environments. I am always impressed by his skill in rendering natural spots and moods, and I truly enjoy the "philosophy" implied in his shots and captions.
It's a true pleasure for me to visit his stream regurarly ! Gradually, Luis style and approach to photography became a "model to pursue" in developing my own passion for photos !
After years of mutual frequent visits, I feel to have gained a good friendiship with Luis, even if we never met personally."10th November, 2008

"Retinol... what can I say? His photos are all equally stunning and each one deserves some alone time to completely discover its true beauty... every image captured is a true beauty in time and location.
Ofcourse as humble as he is, he's a great photographer. He also had some time to spare for some amateurs :-) for tips and hints.
I look forward to seeing more of your work... and thanks Retinol!"5th May, 2008

"Retinol is someone who is very methodical about his images. Only the best are on his stream and it shows.
Having met him in the Pro portfolio group here on Flickr, he is passionate not only for photography but for life itself. Even though he is in the medical profession you would never know that from the images that he, very fluid and graceful
There is no one quite like him here on Flickr and I am happy to say that he is a great friend!"9th December, 2007
