"My Steps"

The work shows the appearance of Yuguchi's monologue, and the appearance of Mr. Usui, who produces the prosthesis, is projected in a cut -back.A work depicting a positive figure that runs toward the future with the thoughts of Yuguchi's feelings.

A small and lightweight single focus lens that can shoot using mobility!

レンズの描写も統一されており、ＲＡＷ収録も組み合わせればカラーグレーディングの自由度も上がる

The shooting this time was conducted in two days: Yuguchi's practice, competition scenery, and Usui's prosthetic production scenery.The shooting is mainly equipped with LUMIX S5 in DJI RS2, and Black Magic Raw is recorded with Black Magic Design Video Assist5 "12G HDR with RAW output of HDMI. Basically 4K/60p is recorded, but in Lumix S5, LUMIX S5Since it is cropped by APC-S, it is full size in the situation that we want, and it is 1080/60p that can be photographed with 60p.

Works that were made with the performers

I've been shooting a play and a story, such as movies and commercials, so I got this story, and instead of just shooting to evaluate cameras and lenses, I made something that I could see and feel.I wanted it.The appearance of trying something is very large, and if you can express it well, you can get a lot of things.While doing research with such a theme, this work was realized by meeting wonderful people, Yuguchi and Usui.

Although this work is a non -fiction, I would like to make something to convey with the performers as a bystander as a side viewer, but to understand the other person.I wanted the performers to think that they were making them together, not the feeling of "taking a picture on their own."

Monologue is also Yuguchi's own words.In the first reply of the email I requested, I wrote my feelings in a very long sentence, and when I saw it, I thought it was connected.It was not a word that asked me to talk, but a monologue that expresses what I thought straight.

There is no need to re -balance the gimbal 4

The shooting was performed from Yuguchi's weight training scene.There are other people who are training in the gym, so I shoot with a gimbal without a tripod.APS-C was selected to record at 4K/60p using 50mm and 35mm lenses.

I used 35mm for cuts such as lifting heavy things in the middle.This angle of view was understood by the background of the space, but there was not too much information, and I felt that I was training alone.Also, when you really want to take a wide last cut, I give up 4k/60p and use 24mm.

In this way, we proceeded with the shooting while replacing the lens, but when replacing the lens, there is no need to balance the gimbal, so it is good to be able to change the lens smoothly.

4本のレンズの描写性能を統一

▲ F1.The 8 single -focus series is designed so that there is no difference in each cut by unifying the description performance throughout the series even if the lens coating is replaced with the lens coating etc. as well as the lens coating.In December last year, 35mm joined the lineup, four lenses were available, and a new 18mm wide -angle lens was added to the development roadmap.

重量・重心がほぼ統一されている

▲ The weight and center of gravity are almost uniform, and the lens replacement is smooth even when the gimbal is installed.This time, I used the wireless follow -focus to shoot in a style where the shooting assistant sends a focus, but the location of the focus gear was the same and I was able to exchange lenses without changing the position of the follow -focus.

Filter diameter that requires one step -up ring

In this shooting, I followed the full lens with follow -up and controlled it remotely.Follow -focus is attached to the lens, but when the size of the lens changes, it is necessary to adjust the position of the gear each time, so it takes time to change the lens.But F1.The 8 single focus series is almost the same size, so the gears can be attached to almost the same position.The operation feeling did not change, so it was just like changing the lens.

The filter wants to reuse one even if the lens changes, so the largest 82mm diameter is installed through a step -up.This time, I used this 82mm diameter filter, but the four lenses have the same filter diameter, so it is helpful that step -up rings are common.

As with anything, I'm worried about various things when things go well, but LUMIX S5 and F1.The 8 single -focus series lenses can be taken without any problems, so you don't have to worry about it.

フィルター径も統一

▲ All filter diameters are unified to 67mm.In this outdoor shooting, the PL filter was mainly used, but the filter change was smooth when replacing the lens.Iwakura used a step -up ring because he owns a 82mm diameter filter.

リニアでフォーカスを送れる

▲ This time, Iwakura -san took a full -length focusman to perform MF operation according to his daily shooting style.Focus operation is set for linear.The rotation angle of the focus ring can also be set according to your preference.

The biggest attraction is its lightness that blends into nature in the field

The depiction of the lens is a very organic feeling that it changes slowly and naturally, rather than falling from the focusing part to the blur.

Also, in grading, the color is often required to correct the color every time the lens changes.But F1.The four single -focus series are the impression that the colors are available.

This time, I used 4 pieces of 24mm, 35mm, 50mm, 85 mm, but if you were asked what focal length you would like as the next one, it was the wide -angle side.Assuming 4K/60p, it will be taken with APS-C, so if it is 24mm, the wide feeling will be lost.Even if you can stop by later, it is more difficult to pull.In that sense, it is good news that 18mm joined the development roadmap.

In addition, movies are often shot at Super 35, and the APS-C is easy to imagine the relationship between the size of the subject and the spread of the background.After all, it is Super 35 that people watching movies are familiar with.With LUMIX S5, you can use the difference between full size and super 35 well.

This time, LUMIX S5 and F1.The biggest attraction is the lightness of using the 8 single -focus series lens.This lightness is a weapon in a shooting that requires a sense of speed.It is a size that can be taken to location hunting, and you can search for an angle at the same angle of view as the S1H.Still, you can take RAW with HDMI output.In addition, it is easy to take a picture of a documentary naturally in the field.

ミニ三脚に取り付けて

▲ In the jumping scene of long jumps, the camera was attached to a mini tripod and buried in the sandbox (production is protected by vinyl).The high flame rate shooting of 4K/120fps was performed.It is unique to small cameras that can be used in this way.

デュアルネイティブISOを搭載し低照度撮影でも低ノイズを実現

▲ LUMIX S5 has a low illuminance environment that requires ISO4000 or more during V-Log, and the base sensitivity is automatically switched to ISO4000 (usually bass sensitivity 640), shooting using low noise and high ISO circuit.Can.In this shooting, I also shot a land truck scene at night, but I was able to shoot a video with noise.

デジタル一眼ながらシャッター開角度の設定も可能

▲ LUMIX S5 supports shooting with shutter opening as well as the S1H of the upper model.In addition to the user -friendly menu screen that is friendly to entry users, a full -fledged video camera menu is also available.It is a nice point for Iwakura who usually deals with cinema cameras.

Color grading becomes efficient

F1.8 In the single -focus series, the description performance is unified as described above, and there is no difference in colored color and aberration texture due to lens replacement, and post -processing such as matching the color when color grading can be omitted., You can concentrate on the original color.In this work, Panasonic's LUT provided by Panasonic is used for each cut.

RAW出力を外部レコーダーで収録

▲ LUMIX S5 is installed on DJI RS2, and Black Magic Design VIDEO Assist5 "12G HDR is attached to Smallrig arm. Some high -frame rate photography and wide angle of view are included, and 8 -bit and 10 -bit materials are also included.However, basically, 4K/60p RAW was recorded with HDMI output.

VARICAM LUT LIBRARY

▲ A LUT library developed by Panasonic with American film officials.35 types of LUT can be downloaded free of charge.In this work, I used "Vintage" LUT.

レンズによる色の差異もなくカラーグレーディングそのものに集中できた

▲ In this work, I wanted to give a texture like nostalgia and reminiscence, so I hit the LUT of "Vintage" to all cuts.The photo shows LUT on the material recorded by RAW, and is applied to primary color grading such as contrast adjustment.Even this alone has a good color and makes you feel the goodness of the sensor.There was no difference in color due to replacing the four lenses, so I was happy to be able to omit the correction time and concentrate on the color making.

VARICAM LUTはスキントーンがキレイに出た

▲ The left is the LUT of Vintage.The right is the condition of adjusting the contrast and increasing the saturation.The reason why Iwakura chose this LUT is that the skint tone comes out beautifully so that the skint tone indicator overlaps the vector scope.

10bit収録の素材も秀逸

▲ I wanted to shoot the last scene with a wide angle of view.In 4K/60p, it was cropped to APS-C, so it was set to 1080/60p and recorded in VideoSSIST in Prores 422 HQ.Only the LUT is adjusted and the contrast is adjusted, but this has been established.The 10 -bit color science was excellent enough to be afraid of the RAW material, which should be used based on which one.
