Photography authenticated globally through the blockchain using independent, immutable NFTs.
Four photography collections originated in 2022, when I discovered the immense potential of decentralized authentication through blockchain and IPFS.At first, the collections were minted using Polygon POS due to its low fees. There are over 7,000 1/1 NFTs minted over several months.Later, I migrated the collections to Polygon zkEVM as a more secure long-term solution.More recently, Ethereum’s upgrades have allowed me to deploy my smart contracts and migrate my collections directly to the Layer 1 (L1).
Freeze an instant in time, which everyone can enjoy, in a decentralised way.
Colour, contrast, composition, everything to evoke tranquillity, joy, sadness, fury.
Colors of Seville Collection. 6 photographs taken on the streets of Seville, Spain. 4 separated editions, limited to 6666 1/1 NFTs, minted using an ERC721 smart contract on the Ethereum blockchain.Collection migrated from Polygon POS (Chain ID 137), first to Polygon ZkEVM (Chain ID 1101) in March 2024 and then to Ethereum (Chain ID 1) in February 2025. In September 2025, the collection has been migrated to the second version of NFTs on Ethereum. Same photos, but improved NFTs with the correction of minting errors; The image field was added to the metadata and the properties field was changed to attributes to comply with the ERC721 metadata standard; Addition of the Chain ID and Token ID as well as the minting date to identify the NFT on the blockchain and authenticate the artwork.Regarding the structure of the metadata: The Token ID of each NFT contains information about the edition and the photograph that certifies this NFT. Example: Token ID 2260 informs us that this is copy 2 of the Ruta al Palacio (Gold Edition). Some NFTs TokenID ends on 1 or maybe 2. This means that the NFT has been reminted due to an error in the first mint.The erroneous NFT and the previous version has been sent to the burn address (0x000000000000000000000000000000000000dEaD).Important Recommendation: For the long-term survival of this NFT, you should keep multiple exact copies of the metadata file and the PNG file of the photo. This allows you to pin them yourself on the decentralized IPFS protocol or authenticate the NFT in case of deterioration of platform infrastructure or IPFS itself.Image Usage License: CC0Ethereum Collection V2: 0xb0260d8b73e7E08096dcc62C5491bb735c3BE583Ethereum Collection V1: 0xd76D53A86a8fbC1A5e76Ea9b55dcf1c1C05c8C09Polygon ZkEVM Collection: 0xA2376be1D597e2E8AE102Ca2d47360F3FfD84846Legacy Polygon POS Collection: 0xa93Dd827649712594421fca090bdDA0fDe7525d0NFTs are available through the following methods:1.
