Jimmy (L) and Muse are chasing the laser pointer dot.
I'm submitting this for the "having fun" theme for the Happy Caturday group.
This was a low-light situation, but I like this grouping of laser pointer enthusiasts. Muse is waiting for the light to hit the door; that's his favorite spot to jump high & "catch" the dot.

Our daughter Ella Violet sleeping in her bassinet at night. She usually sleeps with the little glow in the dark wireless night light dude (from TykeLight) but usually he's up on the rim of the bassinet (we had to move him for better lighting). Ella has just about out grown the bassinet and we are going to change it into a larger crib today.
The bassinet is round (a Stokke Sleepi) and the effect is further exaggerated by using a fisheye lens.
I have another version of this photo during the day while she is awake.
Tech Detail: Canon 5D with a 15mm f/2.8 fisheye lens attached, mounted on a Manfrotto 3021BPRO tripod (322RC2 grip ballhead) with the center column in the horizontal position so the camera was in the middle right over the rim of the bassinet. I used a shutter release cable to reduce camera shake when firing the camera.
The focus point was set manually before the lights went out, and I choose a 4 second exposure to give me enough time to draw the heart with a laser pointer, and I was able to get f/5.6 with ISO400. Some minor color tweaking done in Lightroom but this shot looks pretty much as it did out of the camera.
NOTE: This photo made it into Flickr's 'Explore" as one of the top five hundred most interesting photos on a particular day, which makes me somewhat sad as the actual resulting photos didn't make it, ha! You can see all of my photo's that have made it into the Flickr Explore pages here.
Red laser pointer, Instax Wide format film. Odd how the laser at its brightest turns out blue. Anyway; how did I do this?
1. Put instax camera with film already in it, and laser pointer in lightproof changing bag having noticed how many shots you have left.
2. Zip up. Take off watch that glows in the dark!
3. Put arms in arm holes, locate camera and take out film pack.
4. Orient film pack correctly (sensitive area facing up).
5. Place laser pointer on film, switch on and guess-draw some sort of "interesting pattern".
6. Switch off laser pointer.
7. Replace film pack in camera.
8. Unzip and remove all articles from changing bag.
9. Switch on camera and press shutter to release/develop photo; the camera thinks the image is the darkslide that protects the film pack.
10. Marvel at the unreal colours.
11. Scan and post on Flickr for worldwide admiration.
I asked "an expert" why the red laser was turning up blue here and he said this:
"If I had to guess I'd speculate that this is what's going on. Film
emulsion contains three different sets of chemicals (possibly in
separate layers ?) which deal independently with the red, green and blue colours. The laser is monochromatic - it only emits red light - so you'd think that the blue and green processes would never get activated, and in general that's what we see. At very low intensities the red process works as we would expect and we get the nice red parts of the picture."
"At higher intensities we "burn out" the red process (the laser beam will be quite sharp-edged and the intensity where the black central line is could easily be hundreds of times higher than in the red surrounding region). Let's say ordinary low-intensity light turns chemical A into chemical B and it's chemical B which makes the red colour when it's developed. Too much red light turns B into some other chemical - say C, which doesn't develop to red. Or perhaps it produces an additional chemical (D) which somehow poisons the developing process. In any case we get burnout."
"The appearance of blue in some places will be something different again. It won't be the laser intensity which is varying (intensity is power per unit area and the laser power and beam size will be constant). The blue spots probably appeared where the artist stopped moving the laser beam for a few seconds. Holding a fixed intensity beam still will cause the local temperature of the emulsion to rise and it may be that it's the heating which is triggering the "blue" chemistry. Or, perhaps, there's some leaching of the copious amounts of chemical C (or D) from the heavily saturated red process into the blue layer ? But now I really am guessing."
"The one thing I can say is that there's unlikely to be any blue light involved. In principle it is possible to add two red photons together to make a blue one but this process (called "nonlinear optics") usually requires intensities many orders of magnitude higher than you can get from a hand-held laser."
Kevin gave me the prompt "Disconnect" because I didn't have any ideas for today's photo. I feel like we can all resonate with it. Also... annoyingly, I just learned that our outlet is crooked.
Macro Monday: #Timepieces
Always, always, always the sun. Isn't it? But what if The Sun Ain't Gonna Shine Anymore? Will time be relative then? It certainly is relative (and totally irrelevant) here. Or, as it says on the box this small stainless steel sundial (a present) came in, "When there's no sun, I'm silent." And silent (or just very patient with me and the things I did to it) it was, because the sun didn't show up all Sunday. No sunshine, no time. If it ever was that simple ;-) So I tried a few resuscitation procedures here, especially with the (in)famous star filter which also provided the bling I couldn't get last week - so I apologize for the bling overdose -, and a laser pointer. The way this small sundial, which you can either wear as a pendant around your neck, or as ring, works, is that there is a movable middle ring with which you set the month (on the outside of the sundial). There is a small hole on that middle ring, through which the sunlight, if available, should shine and then highlight the correct time / number inside of the sundial.
So it's obvious what I tried to do here. Use the laser instead of the unavailable sunbeam, shine it through the tiny hole (1 mm / 0,0393701 inches in diameter), and make it show the correct time, or rather highlight the desired number. Or, let's be honest, highlight any random number at all. It was a rather fiddly-fidgety affair to shine the laser throught the hole, and make the laser beam visible around the hole and inside of the ring, and I didn't succeed very often (while also trying to avoid looking directly at the ring and kind of risk scorching my retina because of the reflection).
This is a manual focus stack made of two images in order to get both the outside and inside of the ring sharp, in-camera didn't work that well this time. I also ran out of time again, as I could only begin to take pictures on Sunday evening. I wish I'd had more time for this (I always do; how about starting to take captures earlier during the week then, Silke?), but this'll have to do, as I'm also very busy today. Processed with the usual suspects: Luminar 3: Accent-AI filter set to a low value, something like 20 on the slider, small detail enhancement ("full force" 100), and just a little of the medium and large details, and (subtle) HDR effect in ON1 Photo RAW (which seems to be my favourite ON1 filter). Decreased highlights / whites just a little in LR and increased the saturation of the red, green and blue tones.
Size of the sundial: 19 mm / 0,74 inches in diameter
A Happy Macro Monday, Everyone!
Zeit ist relativ
Oder? Hier schon. Wie heißt es doch auf der Bedienungsanleitung für diese kleine Sonnenuhr: "Fehlt die Sonne, bin ich stumm." Und die Sonne fehlte, ließ sich den ganzen Sonntag über nicht blicken. Also musste ich mir andere Wiederbelebungsmaßnahmen für den kleinen (19 mm Durchmesser) Stahlring einfallen lassen, und so kamen der berüchtigte Sternfilter - für das Extra-Geglitzer, das ich letzte Woche nicht hinbekommen hatte; ich bitte, die leichte Überdosis "Bling" zu entschuldigen ;-) -, und ein Laserpointer zum Einsatz, mit dem ich die fehlenden Sonnenstrahlen zu simulieren versuchte. Das Prinzip der Sonnenuhr, die man als Anhänger um den Hals oder als Ring am Finger tragen kann, ist simpel: In der Mitte befindet sich ein beweglicher Ring, mit dem man den den aktuellen Monat (außen mit den Anfangsbuchstaben aufgelasert) einstellen kann, und ein kleines Loch, ca 1 mm Durchmesser, das sich dann neben dem eingestellten Monat befinden sollte. Jetzt muss nur noch ein Sonnenstrahl ins Innere des Rings (dort sind die Zahlen aufgelasert) fallen, der einem dann die korrekte Zeit anzeigt.
Es ist unschwer zu erraten, dass der Laser hier nicht die korrekte Zeit anzeigt. Es war schon ziemlich fitzelig-fummelig, den Laser überhaupt so zu halten, dass er nicht nur auf dem Loch auf der Ringoberseite, sondern auch in der Nähe irgendeiner Zahl auf der Ringinnenseite als roter Punkt sichtbar wurde. Und ich habe dabei auch lieber auf's Display geschaut, anstatt auf den Ring, weil durch den polierten Stahl die Reflektion des Laserstrahls doch recht hell war. Und meine Netzhaut verschmoren wollte ich mir nun auch nicht unbedingt.
Ich hätte gerne mehr Zeit für's Foto gehabt (früher in der Woche damit anzufangen, wäre durchaus mal erwägenswert); so muss dieses reichen. In Luminar 3 entwickelt: Accent-AI-Filter (so ca. bei 20), Details klein voll aufgedreht (100) und dezente Detailverbesserungen im mittleren und großen Bereich; außerdem wieder den HDR-Effekt (subtle) in ON1 (anscheinend mein momentaner Lieblingsfilter) angewendet. Das Bild ist außnahmsweise ein manueller Fokus-Stack aus zwei Fotos (hat in der Kamera dieses Mal nicht so funktioniert), damit sowohl Ringaußen- wie Ringinnenseite scharf sind.
Ich wünsche Euch eine schöne Woche, liebe Flickr-Freunde!
These are always fun to do. I used a keychain LED flashlight and a red laserpointer pen. Shot it using a 30 second exposure to give myself enough time to draw everything. This shot took me eight attempts before I got it the way I wanted it. My first attempt, I made the head way too big, and i ended up drawing the heart on the head. lol. Also did a few variations as well, like one with the heart in the hand, and also did an E.T. one.
Painting light with with a laser pointer on paper just in front of the camera.
Usually light painting photographs show the "painter" because someone has to hold the light, but for macro photography, that doesn't work.
I could probably paint better than squiggles with practice. The line is curvy enough, but there are some nice curves in the halo due to the angle of the pointer.

Not my idea, I just love the t-shirt design.

something new for me, flash yields laserpointer, handled as any other lightsource, off camera axis and positioned; top/left
Touch the milky way. Hard to describe the scene that night at the Lago Grey, Patagonia. One of my first milky way shots.
Now THIS one was a BLAST to do! ;-) My son is SUCH a trooper!! ;-)

Hey guys, here I want to present you a MOC of the spanish netflix series la casa de papel ( Money Heist or Haus des Geldes) The series revolves a long-prepared, multiple-day assault on the Royal Spint of Spain. The scene shows that the National Police Corps launch an attack and go into the Mint (through the warehouse). The corps use laser pointer on their weapons and 2 robbers (Tokio and Denver) hide behind some boxes.
What do you think ? I know it is no Star Wars MOC but I want to build it because I'm a big fan of this netflix series. So I would be pleased to get feedback.
Maybe I will start a series of some small Vignettes (with the main characters ) to this netflix series. Should I do it?
