私はいくつかの写真をアップロードしましたが、品質の問題で却下されてしまいました。

具体的な理由および改善方法を知りたいです。

ただし、同じような1枚の写真はOKでした(私の最初の写真だったからかもしれませんが)。

 

OKだったもの

If the quality requirements are met, images should be accepted. All images need some processing.

It should be possible to accept astrophotography with image processing; it is necessary even. I wouldn't call reducing highlights, fixing the white balance, decreasing noise, etc, 'strong' image processing. It is still photography! The key factor is that the image should look natural!

It may be difficult to say judging from miniatures. They seem to be blurred.

Hello,

One reason could be because of noise in the photo - however as the other got accepted and it has the same amount of noise, another reason could be the centre of the galaxy is a white blob. So, if you reduce the highlights you can get more detail in the centre:

11-1highlights.jpg

 

Try to reduce the noise as well if you can.

こんにちは、お返事ありがとうございます。

 

当スレッドに投稿した銀河以外にも、9枚ほど投稿していますが、おそらく同じような理由(ノイズが多い)で却下されたしまったのだと理解しました。

最初の1枚だけ受け入れられたのはビギナーズラックだったのだと思うことにします。

 

私はノイズを減らすことも出来ると思います。

しかし、私は強い画像処理を行うことに抵抗があります。

そもそも強い画像処理をした天体写真を、「写真」として受け入れて頂くことは出来ますか。

親切な回答をありがとうございます。

 

私が投稿した写真は意図的にノイズリダクションを弱めています。私は主に印刷を楽しんでいたので、等倍で閲覧することはあまりありませんでした。

ここで得たアドバイスを参考に、天体写真をデジタルで楽しむための画像処理を学び直します。

 

元気が出来ました。

アドバイスありがとうございました!

You have a large black border on each side of the image which is not permitted.

Hello @Yukihiro Iyama , these are beautiful astro photos. Did you take them? These photos would require image stacking. This would result in several 100 photos. If they are not your photography work, you will need an IP release. Again, they are good examples of astro photography.

こんにちは

お返事ありがとうございます。

 

あなたのご指摘の通り、これらの写真はノイズを除去するためにスタッキングをしています。

 

・スタックに使っている写真は全て私が撮影したものです。

・私は同じ日に撮影した画像だけをスタックしています。

・おおよそ8枚から16枚くらいほどスタックに使用しています。

・撮影にはNikonの望遠鏡とNikonのDSLRと使っています。

 

IP releaseとはなんでしょうか。

私は調べて見ましたが、分かりませんでした。

教えてください。

Congratulations! I think your photos are good. Sure some problems, such as an overexposed center in the Andromeda. Still, very impressive.

I have seen several persons who have tried to offer photos taken by others. An IP release is a release of intelectual property. Because these photos were taken by you, this is not needed.

No need for a Property Release, the space is not private property and the contributor agreement says that you should only upload own pictures.

 

As for getting one picture accepted, the other not: It is enough to have 2 different moderators looking at the pictures, when there is noise, but it is not excessive.

 

As for the noise reduction, you could test external noise reduction programs like DeepPrime (from DxO), which provides excellent results. With astrophotography, however, denoising will need to be handled carefully, not to eliminate the stars.

 

I, too, think that your pictures are great! 🙂

はい、投稿した写真は意図的にノイズリダクションを弱めています。

私は主にプリントして楽しんでいるため、等倍で閲覧することはあまりないのです。

 

ご指摘の通り、天体写真ではシグナルとノイズの境界がとても曖昧で、ノイズリダクションはとても奥深い処理です。

私はここで得たアドバイスを元に、デジタルで楽しむための処理について学び直そうと思います。

もちろん、あなたにご紹介頂いたDeepPrimeについても改めて調べてみようと思います。

 

とても元気が出ました。

アドバイスありがとうございます!

Yes, but you need a property release not for your pictures, but when you're photographing private property. With your contributor agreement, you guarantee that the pictures you upload are yours. Because you upload the pictures, and you put them up for sale on Adobe Stock you allow Adobe to sell licences of your material. So, you gave permission to use them.
