LepSnap: iOS & Android Smartphone Imaging

Please visit LepSnap.org to learn more about the LepSnap smartphone project and how to pick a phone, an image app, and dos and dont’s.

How do I know if my smartphone will work?

If you have an iPhone, LepSnap works on all models and all versions of iOS. However, we highly recommend the phone is running the most current version of iOS, to benefit from the full capabilities of the app.

An Android version of LepSnap is under development and being beta-tested (Jan 10, 2018) with the aim to be as functional as the iOS version by April, 2018. If you have an Android phone, LepSnap will be compatible with the following devices:

  • Google Pixel (all)
  • Google Nexus (4 or newer)
  • Samsung Galaxy (S5 or newer)
  • Samsung Note (4 or newer)
  • OnePlus (One or newer)
  • HTC One (M8 or newer)
  • Motorola Moto X (or newer)

LepSnap will be compatible with most other Android devices equipped with Android 4.4 (Kitkat) or newer, but prefer 5.0 or newer to support in-app animations. If you are uncertain if a prospective model will be supported, please let us know and we can run the app in a test environment that simulates that modal and Android version to confirm.

In addition to compatibility, not all phones are created equal in terms of image sensor photo quality. There are several reviewers that provide objective reviews of phone cameras, finding consensus among 2-3 will provide one with good options.   The camera should have 4000 pixels on the long side. This DxOMark website provides DxOMark Mobile ratings, mobile reviews and explanations on how DxOMark is testing camera-embedded mobile devices.

Can I use an iPad to photograph specimens?

Yes.

What imaging program should I use?

There is a built-in progam in LepSnap app, but you can use any program you want and upload images to LepSnap. It is highly recommended that your subjects are brightly illuminated with daylight color temperature LEDs or flash system to minimize the need to edit images. If you must edit, the following apps are recommended:

  • Adobe Photoshop Express (free)
  • Adobe Lightroom (free)
  • Instagram (free)
  • Pixlr (free)
  • VSCO (free)
  • Manual ($3)
  • Camera+ ($3)
  • ProCamera 9 ($5)

 

White balance and ruler?

When photographing the specimen over a neutral gray background (ideally 11% gray), white balance can be corrected using the background. We do not recommend color charts unless the specimen photos are going to be used on high-end printing. Visually, a small mm or cm line to show scale is preferred over photographing with a rule in the background.  Neil Cobb is selling gray plates for cost 

 

Should I just take the image and upload or can I edit and send?

LepSnap allows you to use the in-app camera to photograph the specimen and publish it at one fell swoop. You can also use the camera app that is native to your phone if you want to edit the photo before publishing it on LepSnap. You may also publish photos taken by an external camera, since you can select photos from your phone library to publish on LepSnap.
