pada percobaan kali ini saya menggunakan software JPEGsnoop
Langkah-langkah untuk Proses file :
file JPEG dengan File-> Open ...
Simpan output dengan File-> Simpan Log ... jika diinginkan
Sebagai alternatif, Anda dapat drag-and-drop file JPEG ke ikon JPEGsnoop atau jendela utama dan laporan secara otomatis Membuka file JPEG secara otomatis akan memulai proses decoding dan generasi dari file log.
Ada beberapa pilihan dapat mengaktifkan decoding file JPEG . Jika opsi Auto ulang di jendela Konfigurasi dinonaktifkan, maka setiap perubahan pada Pilihan di bawah ini tidak akan tercermin dalam log sampai berupa file baru dibuka, atau Anda secara manual File-> ulang.
•Hide unknown EXIF tags - Opsi ini akan menonaktifkan decoding tag EXIF yang saat ini tidak dikenal di's database JPEGsnoop
•DHT Expand - - Perluas yang JFIF Huffman tabel kode ke daftar aktual dari variabel-panjang string biner yang dicari selama proses decoding
•Scan Segment - Decode Image Pilihan ini ternyata di decoding nyata dari segmen data Scan.Dengan demikian, beberapa pemeriksaan dilakukan untuk memastikan bahwa semua kode panjang variabel adalah valid dan bahwa tidak ada korupsi data.
•Scan Segment - Histogram RGB Jika Decode Image diaktifkan, pilihan RGB Histogram akan menampilkan histogram untuk komponen RGB, selain pelaporan setiap YCC / RGB kliping.
•Scan Segment - Histogram Y - Jika Decode Gambar dan RGB Histogram pilihan diaktifkan, pilihan Y Histogram akan menampilkan histogram menggambarkan pencahayaan (Y) DC komponen gambar.
•Scan Segment - Full IDCT - Bila pilihan ini diaktifkan, proses scan decode tidak seorang IDCT penuh (Inverse Discrete Cosine Transform) untuk menghasilkan tampilan gambar resolusi tinggi.
•Scan Segment - No IDCT - Bila pilihan ini diaktifkan, proses scan decode tidak melakukan IDCT, dan dapat menghasilkan resolusi gambar tampilan-rendah
•Scan Segment - Scan Dump - Mengaktifkan opsi ini dumps keluar 640 byte pertama dari scan data (dalam mulai dari Scan (SOS) segmen) dalam heksadesimal, setelah memasukkan byte telah ditangani
•Scan Segment - Detailed Decode... - Gunakan opsi ini untuk membuang keluar info rinci tentang VLC Huffman (variabel-panjang kode) yang membentuk bitstream Scan
•Maker Notes - Decode Maker Catatan bagian (-spesifik data produsen) jika itu adalah membuat didukung oleh JPEGsnoop.
•Configuration - Membuka sebuah jendela di mana Anda dapat mengatur beberapa opsi tambahan.
demikian dulu penjelasan tentang software yang saya gunakan kali ini jika ingin lebih jelasnya bisa langsung ke situs resmi JPEGsnoop nya. ok kita mulai percobaannya
pertama-tama saya mempersiapkan 2 buah foto, foto pertama asli dan belum terkena editan dan foto yang ke 2 adalh foto yang sama tetapi telah saya edit sedikit, kemudian jalankan software JPEGsnoop kemudian buka foto percobaan satu maka akan langsung tampil hasilnya , begitu juga foto yang ke 2:

dari data-data diatas coba tebak mana yang asli dan mana yang bukan? hayo tebak masih mo coba tebak gk ? udah yuah pe sini ja biar penasaran :lol:
gk deh bercanda jangan ambil batu ah mending ambil uang ja dri kantong terus lemparin ke sini hehehehehe, okelah saya teruskan, saya akan coba menerangkan hasil dari analisa diatas coba teman-teman perhatikan hasil analisa dari ke-2 percobaan diatas ada yang beda gk ? yup benar sekali ada perbedaan tampak jelas sekali pada bagian

sangat jelas bukan perbedaannya sudah taukan perbedaannya dimana ?ko belum c ? masa? pa cuman pura-pura nih eheheehe nah betul itu dia maksud saya terrnyata kamu sudah mengerti kan, ya memang jelas sekali terlihat pada keterangan
[spoiler][Software ] = "FDi V4.5 / FRONTIER355/375-1.7-0E-105"[/spoiler] pada bagian yang pertama dan menunjukan software yang digunakan untuk mengambil foto tersebut
dan yang kedua memiliki keterangan sebagai berikut dan menunjukan foto diambil dengan menggunakan sofware ACD SYSTEM
[Software ] = "ACD Systems Digital Imaging"[/spoiler]
perbedaan yang ke-2 adalah pada bagian akhir

data diatas menerangkan tentang perngkat keras,sofware,jenis perubahan yang telah dilakukan dan juga kwalitas gambar yang dihasilkan, saya rasa cukup sekian artikel kali ini semoga teman-teman semua dapat mengerti apa yang saya tuliskan, saya hanya seorang pemula yang belum ada apa-apanya dibandingkan teman-teman semua oleh karena itu jika masih banyak kekeliruan mohon dimaafkan dan diluruskan agar saya dapat menjadi yang lebih baik lagi
