To figure this out, it decided to conduct a rough test of these two apps.<\/p>\n<h2>The test protocol<\/h2>\n<p>To compare the output of these apps , I took a series of photos with two smartphones stuck together, at the same time, in the same place. <em>Hipstamatic <\/em>is running on my old iPhone 3G, <em>RetroCamera <\/em>was installed on my brand new Motorola Defy.<\/p>\n<p>There are obviously several biases in this approach :<\/p>\n<ul>\n<li> The camera and CCD of both phones are technically uneven.<\/li>\n<li> The apps don&#8217;t provide the exact same filters and effects.<\/li>\n<li> The framing and aperture of the phone&#8217;s lenses are different too.<\/li>\n<\/ul>\n<p>However, as you can see below, I found the output photos to be surprisingly close, and especially close enough to compare the way each app can work. The framing is exactly the same, the color treatment is somehow similar, with a vignetting effect.<br \/>\nOf course, the Motorola Defy took a sharper photo with its 5MPixels camera, but in my opinion it is not a relevant criterion.<\/p>\n<table>\n<tbody>\n<tr>\n<td><a href=\"http:\/\/farm6.static.flickr.com\/5137\/5435223239_025da2c996_o.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" title=\"Hipstamatic (left) VS RetroCamera (right) Shot #28\" src=\"http:\/\/farm6.static.flickr.com\/5137\/5435223239_ebdc02cb7f_z.jpg\" alt=\"\" width=\"580\" height=\"292\" \/><\/a><\/p>\n<p><span style=\"color: #808080;\"><em>Left : Hipstamatic.

This happens when the light enters the camera, either through the lenses or the leaks previously mentioned.<br \/>\nThen, the purpose of the level process is to get the image burnt, under\/over exposed, which is typical on a toy camera or a Polaroid on which the exposure is static.<br \/>\nEventually, after the light came through the 2 previous filters of a rough exposure, a coarse lens and a leaky camera body, it will hit the film, and that&#8217;s what the color correction is about, because every color film has a different color response to the light.<\/p>\n<table>\n<tbody>\n<tr>\n<td><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" title=\"RGB Color Response of a fake vintage photography.\" src=\"http:\/\/farm6.static.flickr.com\/5252\/5442276950_011d149793_o.jpg\" alt=\"\" width=\"580\" height=\"191\" \/><br \/>\n<em>The diagram above shows what kind of RGB transfert curves is applied to the raw image to mimic the color response of a real film.

I my opinion, only the final result matters, even if it is not technically correct.<br \/>\nBesides, it&#8217;s important that such apps provides a lot of various settings &amp; camera modes, because each user will look for a specific result and atmosphere.

RetroCamera made something almost monochromatic, which is very strange considering the result on the other photos with the same filter (where the blue tint is actually less strong than on the iPhone app). <\/em><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Effect control<\/h3>\n<p>To emphasize the look of your vintage photo, both apps can add a wide range of different frames : a sober white frame of a polaroid, the torn sheet of Ilford paper, the side of a reel, and so on.<br \/>\nThere is one major difference I could notice between the two apps : <em>Hipstamatic<\/em> allows the user to choose independently the film effect and the frame, which <em>RetroCamera<\/em> does not.<br \/>\nHowever, I suspect this won&#8217;t be an issue for most users, except for those who will find the torn or scratched frames a bit too cheesy \ud83d\ude42<\/p>\n<h3>Processing time &amp; reactivity<\/h3>\n<p>I didn&#8217;t spent too much time to benchmark the processing time of each app. It wouldn&#8217;t have been relevant because my iPhone 3G is a bit slower than my new Motorola Defy. Processing a full resolution photo on my iPhone can take up to 20 seconds, whereas the process is almost immediate on the Motorola Defy.<br \/>\nFurthermore, it is unclear to me wether these apps have the same kind of process, or not.<\/p>\n<p>Anyway, in my case, having to wait 30 seconds between each shot is not a real issue. This quite close to my old Polaroid, and it helps me to think wisely about my next photo.<\/p>\n<h2>Conclusion<\/h2>\n<p>So, Hipstamatic VS RetroCamera, who&#8217;s the winner ? I can&#8217;t honestly tell.<br \/>\nI can&#8217;t consider RetroCamera as a real equivalent of Hipstamatic, because the outputs of these apps are really different. Moreover, the processing flaw I suspect in RetroCamera is a real issue for me. But considering that RetroCamera is absolutely free in the Android Market, it would strongly recommend to test it, anyway \ud83d\ude42<\/p>\n<table>\n<tbody>\n<tr>\n<td><a href=\"http:\/\/farm5.static.flickr.com\/4135\/5435217409_2cba147d0b_o.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" title=\"Hipstamatic (iPhone) VS RetroCamera (Android) Shot #01\" src=\"http:\/\/farm5.static.flickr.com\/4135\/5435217409_584eb60531_z.jpg\" alt=\"\" width=\"580\" height=\"292\" \/><\/a><br \/>\n<br \/>\n<a href=\"http:\/\/farm6.static.flickr.com\/5052\/5435218127_7f501841cf_o.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" title=\"Hipstamatic (iPhone) VS RetroCamera (Android) Shot #05\" src=\"http:\/\/farm6.static.flickr.com\/5052\/5435218127_4d0cbc59af_z.jpg\" alt=\"\" width=\"580\" height=\"292\" \/><\/a><br \/>\n<br \/>\n<a href=\"http:\/\/farm5.static.flickr.com\/4105\/5435831464_d21a577a6d_b.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" title=\"Hipstamatic (iPhone) VS RetroCamera (Android) Shot #18\" src=\"http:\/\/farm5.static.flickr.com\/4105\/5435831464_d21a577a6d_z.jpg\" alt=\"\" width=\"580\" height=\"292\" \/><\/a><br \/>\n<br \/>\n<a href=\"http:\/\/farm5.static.flickr.com\/4120\/5435222953_6834a266a9_o.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" title=\"Hipstamatic (iPhone) VS RetroCamera (Android) Shot #27\" src=\"http:\/\/farm5.static.flickr.com\/4120\/5435222953_85f071a7b0_z.jpg\" alt=\"\" width=\"580\" height=\"292\" \/><\/a><br \/>\n<br \/>\n<em>A selection of shoots.
