Olympus Live Composite - mitä, miksi ja miten?

Live Composite on Olympus kameroiden erittäin käyttökelpoinen pitkien valotusten feature. Se on kätevä tapa kuvata pitkällä valotuksella ilman, että kuva ylivalottuu kovinkaan helposti. Live Comp ottaa peräkkäin useita valotuksia ja yhdistää kuvat yhdeksi kuvaksi kamerassa. Kuvaan tulee ainoastaan lisää, jos kuva-alalle tulee vaaleampia alueita kuin siinä siihen mennessä on ollut. Valotuksen voi lopettaa, kun kuva näyttää omasta mielestä hyvältä. Parasta juuri onkin, että kameran näytöltä voi seurata miten kuva kehittyy.

Saadaksesi Live Compin päälle laita kameran valotus M-asentoon. Valitse valotusajoista Live Comp. Valotusajan pituuden saat valittua Menusta. Kun sinulla on Live Comp. päällä, paina menu-nappia. Kamera osaa mennä suoraan oikeaan valikkoon josta saat valittua yhden valotuksen pituuden. Valotuksen pituus luonnollisesti riippuu vallitsevan valon määrästä. Ohessa olevien kuvien valotusajoista saat jonkinlaisen haarukan valotusajoista, aukoista ja ISO-herkkyyksistä.

Kuten kuvien tiedoista näkee ei kovin pitkiä valotusiakoja tarvitse. Kauanko kameran antaa ottaa LiveCompilla kuvaa on sitten jokaisen oman maun mukaan päätettävä itse.

LiveCompin käyttö vaatii käytännössä jalustan käyttöä.

Olympus vs. Hasselblad

I had a change to test the Hasselblad X1D. Its an interesting camera, a medium format mirrorless camera with a 50 megapixel sensor. It has a price of around 9000€ the body alone. The Finnish Hasselblad dealer Fimeko borrowed me the camera.

First impresssion

I made a first impression video a couple a weeks ago. My Olympus OM-D E-M1 MKII (in Finnish) has a highres mode. With the highress I can make 80 megapixel images with it. It uses the pixel sift technology. Of course there are limitation with that technology.

 

Olympus and Hasselblad head to head!

I wanted to compare my Olympus OM-D E-M1 MKII against the Hasselbald X1D. In the video below you can watch the results. There are also links to to My first impression video on the Hasselblad X1D and a tutorial video about the Highres mode in Olympus cameras.

Can AI replace photographers?

Google Clips is small camera that uses AI to determine when to take pictures and in some cases about what. It is a small camera that can placed almost anywhere and it automatically takes photos of what it considers to be worth a photograph. Of course it does not move and it has to be placed. Clips then decide when to the photo. I understand that it likes movement. So if something moves in front of it, it snaps a photo. It also snaps a photo when a face comes close enough etc. It can recognise the faces that are those ones that are mostly saved on your smartphone from Clips. So it takes more photos of your kids than strangers. I have not used or seen Clip, but that is the basic concept I found out when I read about it.

The interesting question is: Can it replace a photographer? Without seeing the Clips in action I would say no. Even though AI is getting better and better it is not capable of making all the decisions that photographer makes when making photographs, yet. As photographer Ben Long said "The act of photography is the act of expression," (quote from CNN:s article about Clips). So it would be an act of expression of the one that wrote the algorithm, not the photographers.

Even though AI is not near? of getting to be on the level of a experienced photographer, it might be good enough for a common snapper. Clips might be able to take better photos than an average snapper. If placed correctly it can record images that might be good enough from a dinner party for example. Few Clips placed around the table might catch those images that can be used as memories from that party. Most likely it still cannot catch the decisive moment, but on the other hand how many snappers can?

The problem with AI for now is that it can most likely take photos that are taken by the common "rules" of photography. But that is just the start from where a photographer begins to make the image. Very seldom photographs that follow every rule of photography are interesting. The interesting and "a good" photographs are the ones where the "rules" have been broken. There is some creative element in the photograph that the photographer has put in the photo. So far AI cannot do that. But we never know when that is going to happen. Most likely the next step is collabaration between AI and photographers to get better images.

Hämärähommia!

Onko oikein sanoa pimeäkuvaus, hämäräkuvaus vai jotain muuta, kun puhutaan vähässä valossa kuvaamisesta?


Hasselblad esitteli 400 megapikselin unelman.
Kodak esitteli kryptovaluutan.

Ketä seuraat Instassa ja millä perusteella?

Exposure to the right with Olympus OMD

Exposure to the right has always been important in digital photography. Thats the best way to record the most information camera can capture. Olympus cameras, OMDs and most Pen-cameras, can be configured so that your exposure is perfect everytime. 

I made a little tutorial video on how to set up the menus so for the best practice to get perfect exposired. This method was firsr discovered by a finnish photographer Pekka Potka. His blog post about it is no longer available so I made a new one.

The steps to set up your camera:

1. Shooting menu 1 > the triange (4th from top) > raw 

2. Shooting menu 1 > Picture Mode > contrast -2, saturation -2

3. Custom Menu D > Info settings > info >Highlight & Shadow: On (Histogram: Off) 

4. Custom Menu D > Histogram Settings > Highlight 254-245 and Shadow 1-8

5. Custom menu D > LiveBoost: Off

6. Custom Menu G > Color Space: AdobeRGB

7. Custom Menu G > AutoWB > Keep Warm Color: Off

The screen shot from Lightroom shows the histogram of the image that was shown in the video:

As you can see the histogram is almost perfect for and the exposure is correct.

Be sure to watch the video for some more info. Remember to subscibe my YouTube-channel.
