Usisng Using the Sitecore Layout Services /sitecore/api/layout/render/[config]?item=[path]&sc_lang=[language]&sc_apikey=[key]. The json output for each of the 3 fieldserializers can be configured. The configuration can be found in the file App_Config\Include\damforsitecore\DFS.Settings.config. The default config looks like this:

...

1. I want to get the title of the asset
   <property outputName="title" propertyName="Name" />

2. I want to get the Photograph metafield from my Digizuite which has the guid baeefe6b-74df-44be-8a2b-ccfb2c57af8e
<property outputName="photograph" propertyName="baeefe6b-74df-44be-8a2b-ccfb2c57af8e" />

3. I want to get all the folders that the asset is part of. But i want the delimiter to be #.
   <property outputName="folders" propertyName="bf0ad1a6-984a-494e-a227-9d70c6a864f9" delimiter="#" />

4. I want to get the media url with the rendition the content editor selected
   <quality outputName="src" />

5. I want to get the media url with a specific rendition from my Digizuite DAM. The rendition is called Small JPG and has mediaFormatId 50036
   <quality outputName="src_small" qualityId="50036" />

6. I want to get the media url for the source of the asset
   <quality outputName="src_source" qualityId="source" /> or <quality outputName="src_source" qualityId="-1" />

7. I want to get the media url with a specific rendition from my Digizuite DAM and make it a download link. The rendition is called Small JPG and has mediaFormatId 50036
   <quality outputName="src_small_download" qualityId="50036" download="true" />

Crops

If an asset has crops, then it is posible to get a list of the crops in the json respons. You simply add a property called Crops like this.
<property outputName="crops" propertyName="Crops" />

The json output would look like this.

    "assetTypeId": 4,
    "title": "Butterfly",
    "crops": [
